Introduction
Wifi Robot: A remote control car that can be driven over the internet or with a laptop wirelessly from up to 500m away. It has a live-feed network camera so that it can be driven without line of sight and a horn so that you can honk at people.
A while ago I discovered the Linksys WRT54GL router. It's very hacker-friendly in that it runs Linux and some of the hardware has been reverse engineered. A bunch of alternative firmware versions have been written for this router. The version that this project uses is the customizable Linux firmware Open-WRT. Along with great software for this router, a bunch of hardware hacks are possible. With a cheap, hackable, embedded Linux system at my disposal -- I knew I had to do something cool with it. So the Wifi Robot idea was born.
The goal of this article is to give a high-level overview of the project and provide some implementation details of the software and electronics. It is not meant to be a step-by-step how-to guide, but there should be enough information for someone with motivation and some background knowledge in electronics and software to be able to make their own Wifi Robot. All of the source code is being released under the terms of the GNU GPL v2, so by all means, use the code, and improve it!
Hardware
Car
Adding a network camera, router, heavier batteries, extra circuits, and a whole bunch of wires adds a lot of extra weight that the car wasn't designed for. Because of all of the additions, you'll need to find a pretty large RC car. Thrift stores often sell RC vehicles (without remotes!) for $3-5. I have bought a number of cars this way for taking apart. Vehicles in the 1:10 size ratio or bigger are appropriate; you probably don't want to go any smaller. I bought this car for $5 at Value Village.
I have taken apart about 20 RC cars. Nearly every single one of them used the Realtek RX2/TX2 chips or a pin-compatible alternative. The links are for their respective datasheets. What this means is that it's really easy to interface to the car's existing electronics without having to put in a bunch of our own circuitry. It's possible to hook up a microcontroller directly to these pins (Forward, Backward, Left, Right) and directly control the car. Being able to leverage the car's original circuitry saves a lot of time and effort.
Router
I've modified my WRT54GL to have 2 serial ports and a 1GB SD Card (acts like a 1GB hard drive). The SD card is not used in this project, but one of the serial ports is. One is a console port, the other is TTS/1 which we will be using. For this project I'm using Open-WRT White Russian v0.9. There are more recent versions, but we don't need the latest-and-greatest software features for this project. The software compilation guide (details later) uses this distribution, so that is why I chose it.
Later in the article links and information are given that can help you wire up your serial ports and get them working.
Microcontroller Selection
I evaluated three different microcontrollers for this project. Below is a summary of the evaluation.
Microcontroller |
PIC16F628A |
Arduino (ATmega168) Freeduino MaxSerial |
AVR Butterfly (ATmega169) |
Pros |
price |
very easy to program (C with many built-in libraries) integrated serial pre-packaged development kit, little or no soldering involved |
easier to program than the PIC (C) integrated serial little soldering involved |
Cons |
hard to program (assembly) have to wire up the circuit by hand extra serial hardware required (MAX232A) extra programmer required |
price | bootloader error (see below) integrated peripherals cause weird output voltages price |
I choose the PIC16F628A for a few reasons:
- I had a bunch of them around
- I have quite a bit of experience working with them
- I wanted a board with a small footprint, the PIC was the smallest footprint of all 3 options
- I wanted complete control over what the code was doing and this is very possible with assembly programming
I originally used the AVR Butterfly development board. It was working fine until the batteries ran low one time. There is an error in the AVR butterfly bootloader detailed here that corrupts the code and doesn't let you reprogram it unless you load a new bootloader. To me, I just knew my car was working one day and not the next. It took quite a while to debug the problem and quite a bit of time to fix it so I scrapped that control system. I also found the output voltages to be unpredictable because the outputs are also driving the integrated peripherals like the LCD screen.
Below I have included source code for the PIC and Arduino microcontroller platforms. Both have been tested -- so use whichever you feel most comfortable with. The Arduino (Freeduino MaxSerial) would be the most painless way to get running quickly. I bought this one.
Steering Circuit
I'm actually using two control boards in my car. The reason for this is that I blew the original drive transistors on the board that came with the car. Fortunately I was able to remove them and the RX2 chip (which was also blown) and salvage the steering circuit. Most of these toy RC cars have about 6 wires that go in to the steering motor assembly. This is because inside the assembly there's a metallic wiper that moves with the motor and the extra wires are used to relay which position the motor is in. Each different RC car will have a different setup for this wiper circuit, so it's VERY useful to be able to use the one that came with the car.
I blew the drive transistors because I was trying to drive the circuit at ~16V when the battery that drives the car would nominally be 9.6V. The transistors are rated for 5A, but evidentially I was driving them too hard and they failed in a spectacular plume of smoke. I took a board from another RC car and used its drive transistors. I'm running this circuit at 12V and it hasn't caused any problems. The transistors get quite hot though. Being able to use existing RC car circuits and not having to build your own H-bridges saves a lot of time and money.
Batteries
This project sucks some major battery power. I bought some high-end RC car batteries for about $50+shipping on eBay. They're 3800mAh and came with a 1.8A smart charger. They can be found with this eBay search. Each battery takes about 1.5hrs to charge (from being completely dead). They're 7.2V, however when they're just-charged they're ~8.3V and when they're dead (no longer able to move the car) they measure ~7.1V.
I replaced all of the RC battery connectors with standard ATX power supply Molex connectors. This was so that I could connect them using cheap connectors I already had and so that it would be easy to make a splitter connector for doing power measurements. The batteries are wired in series for about 16V when fully charged.
Power Rails
5V (7805 1A regulator) |
9.2V (from 12V-7812 rail) |
12V (7812 1A regulator) |
12V (LT1083 7.5A Regulator) |
microcontroller |
camera |
wifi router | drive board with motor controller |
The 9.6V rail was powered by putting 4 diodes in series with the 7812 12V rail. A diode takes ~0.7V to turn on. By putting 4 in series, we drop ~2.8V across them and now we have 9V for the devices that need less than 12V. After burning the first bunch of transistors I wanted to run the circuit at a lower voltage. The 7812 regulator is only rated for 1A but the motors would drain considerably more than that. Digikey sells a 7.5A 12V regulator for ~$14 which I bought. I attached it to a heat sink because I thought that it may get pretty hot. After quite a bit of use, it doesn't even get warn, so the heat sink was not required.
I didn't want to risk blowing the steering control circuit, so I put it on the rail closest to the original RC car battery voltage. The camera required 9V and the horn wasn't loud enough when I tried it on the 5V rail, so all of these devices are on the 9.2V rail.
All of the power electronics are on a prototype board and are stored under a project box.

The Freeduino MaxSerial serial port can be connected with any standard serial cable to the serial port on the router.
The Freeduino MaxSerial uses serial pin 4 - DTR (data terminal ready) to reset the microcontroller and allow it to download new code. Under normal PC operation this pin is either +10V or -10V depending on whether the serial port is connected or not. However, this pin is grounded on the router serial port and isn't active. When the router serial port starts sending data, the MaxSerial resets. That's no good for us. We are going to pull-up the DTR pin to +9V. With this quick hardware modification, it basically adds a program-locked mode so that new code can't be uploaded and the microcontroller can't be reset by the serial port. If you need to reprogram it, just flip the switch. +9V is a pin with easy access on the Freeduino MaxSerial.
Note: If you're using a usb version of the Arduino, you may be able to just connect the RX & TX pins to a MAX232A and then to the router serial port and may not need this modification. I only have the MaxSerial version, so I can't verify either way.
Camera
(Left Image Source: http://panasonic.co.jp/pcc/products/en/netwkcam/lineup/bl-c1/partnames.html)
One of the coolest aspects of this project is the fact that the car can be driven without line of sight. That is accomplished using a network camera. The one I chose was the Panasonic BL-C1A. It was basically the cheapest wired network camera with good reviews. The software is Windows-only and isn't great, but it's usable. The software is required to get the live streaming view. More expensive models can be had that have pan and tilt capability, but they are considerably more expensive and I didn't need that functionality.
Edit:
As a couple of the commentors have pointed out, the camera actually has a very usable web interface making it not a Windows-specific device. You can view the live feed using the following command:
http://<camera_ip>/ImageViewer?Resolution=320x240?Quality=standard
Available resolutions are 640x480, 320x120, and 160x60. Available quality (compression) settings are precision, standard, and motion.
There's a good summary of the commands and review of the camera at this blog.
(Dimensions Images Source: http://panasonic.co.jp/pcc/products/en/netwkcam/lineup/bl-c1/partnames.html)
The video quality is quite good. However, it will often freeze at a frame for about 1 second and then start streaming again. Even with good connectivity. I'm guessing its controller isn't powerful enough to auto-focus and also keep streaming at times. Overall I'm happy with it.
See the measurements and benchmarks section below for bandwidth requirement measurements.
Looking at the inside of the camera it looks like its running on an ARM processor at 250MHz. According to their parts website, it also includes 64MB of RAM. I wonder how hard it would be to get Linux running on this thing...
Horn
I wanted to add the fun feature of being able to honk at people. It was a pretty simple addition. I bought a $3 buzzer for KW Surplus and hooked it up to the microcontroller using a transistor for greater voltage and current.
Putting it All Together
Only the base of the RC car was used. All decorative and non-functional parts were stripped off. The camera was mounted to the front with only a small modification to the mounting hardware that came with the camera. The circuit boards were bolted to the sides of the front part of the car using plastic nuts and bolts to avoid conductivity issues.
The PIC controller board was also bolted securely to the side of the car. A number of holes were drilled to allow for routing the wires. All wires were intentionally made longer than required so that the pieces could be easily moved around before they were bolted in permanently. After all of the pieces were secured, all of the slack in the wires was collected and zip-tied (see pic in Power section above). There were a lot of wires. Probably around 30 that needed to be routed to/from the front and back of the car, not including the Ethernet cable.
All of the power circuits were housed in the project box on the back of the car, with the exception of the LT1083 7.5A Regulator which is on the bottom of the car. I didn't put it in the project box because it was a late addition to the project (after blowing a board earlier), so it was the easiest place to add it. An LED on the back of the box glows red while the router is booting up. When the router sends an 'alive' message to the microcontroller, the LED turns green and I know that I'll be able to connect with the VB client application. This LED was very helpful when debugging.
All of the electronics were prototyped on a breadboard before being soldered and installed in the car. The batteries were secured using hot-glue and zip-ties. The router was a bit too wide to sit on the car without some extra modifications. I added a couple pieces of plexiglass to make the RC car base wider.
Future [Possible] Additions
There are a couple things I think would be fun to add:
Headlights, just super-bright LEDs. They would be very easy to add to the microcontroller circuit.
Current Sensor that could relay back how much current the car was using and display it in the VB app. The microcontroller could read the sensor and send back the data.
Software
There are three pieces of software that make this project possible. The VB6 Wifi_Robot client application (runs on Windows), the CarServer which is written in C and runs on the router running OpenWRT WhiteRussian v0.9 (Linux), and the microcontroller firmware. I've provided tested firmware for both PIC16F628A microcontroller and the popular Arduino (Freeduino MaxSerial). All software is released under the GNU GPL v2 license.
The following instructions assume you have a Linksys WRT54GL with OpenWRT WhiteRussian v0.9 installed and connected to the internet. See this guide for OpenWRT installation instructions.
Installing CarServer
If you just want to use the software
SSH in to your router then ...
# cd /tmp
# wget http://www.jbprojects.net/projects/wifirobot/carserver_1_mipsel.ipk
# ipkg install ./carserver_1_mipsel.ipk
Compiling and Installing CarServer
If you want to see how it works or modify it yourself
You'll need to download the OpenWRT SDK (Linux Only) and follow this guide for compiling software: Eric Bishop's Writing and Compiling A Simple Program for OpenWRT (just follow Part I)
Makefile place in /OpenWrt-SDK-Linux-i686-1/package/carserver/
Makefile place in /OpenWrt-SDK-Linux-i686-1/package/carserver/src
carserver.c place in /OpenWrt-SDK-Linux-i686-1/package/carserver/src
Your compiled ipkg will show up in /OpenWrt-SDK-Linux-i686-1/bin/packages. Then
# scp carserver_1_mipsel.ipk root@<router_ip>:/tmp/.
to copy it to the router. SSH in and install it.
Great Resource
There seems to a free e-book on the WRT54G series of routers called the Linksys WRT54G Ultimate Hacking. I believe it's meant to be free. Google Books has the whole book viewable. It can also be downloaded here: (password: ____ ) This book outlines how to add a serial port, setup the software, as well as a bunch of other hacks.
Edit: (September 20, 2008)
I've been contacted by one of the authors. It isn't a free e-book. You can view the whole book on Google Books here or for a more convenient format and to support the authors, check it out at Amazon. It's a great book!
Getting the Serial Port Working
We need to use TTS/1, so if you only add one serial port -- make sure its that one. Assuming you have OpenWRT WhiteRussian v0.9 installed, SSH in to the router. The instructions in the book linked above are a bit outdated. Here is the updated version:
# ipkg update
# ipkg install setserial
# cd /usr/sbin
# wget http://www.jbprojects.net/projects/wifirobot/stty.tgz
# tar -zxvf stty.tgz
# chmod 755 stty
Add the following lines to /etc/init.d/custom-user-startup to make the serial port work on start-up and have the CarServer automatically start.
/usr/sbin/setserial /dev/tts/1 irq 3
/usr/sbin/stty -F /dev/tts/1 raw speed 9600
/bin/carserver &
Running Wifi_Robot Client App:
wifi_robot_client.zip
This file contains both the VB6 source code and compiled EXE. You can just extract the wifi_robot_client.exe and config.txt you don't want to deal with the programming stuff. The project will open and compile in VB6 if you'd like to modify it. It's Windows-only, but if anyone wants to make an alternative client app, I'll be happy to post it here and give you credit. This software is just slightly modified from the Computer Controller RC Car project posted a few years back.
Microcontroller Firmware
PIC
You'll need a PIC programmer to burn the firmware. Personally I use a P16PRO40 that I bought on eBay. There are many pic programmers that you can purchase or make yourself for a few dollars worth of parts. You can compile the HEX yourself using Microchip's MPLAB or just download and program the HEX file provided. The PIC asm is based off of this PIC16F628 UART Test guide.
car_pic.asm
car_pic.HEX
Arduino (Freeduino MaxSerial)
You can follow these tutorials to get your Arduino up and running fast. The code can be downloaded to the Freeduino MaxSerial without an extra programmer.
car_arduino.c
If you're using a Freeduino MaxSerial, make sure you complete the small hardware modification that will stop the Freeduino from resetting every time it receives data from the router serial port. See the hardware section above for more technical details of the problem.

Measurements and Benchmarks
Top Speed
To get the maximum speed I setup to tape lines 3m apart and filmed the car while I made several passes. The camera records at 30fps, so I have +/- 3.3% error from the camera and maybe +/- 1% error from the tape lines.
The car could travel 3m in 0.7 seconds (21 out of 30 frames in 1 second).
Top Speed: 4.3m/s = 15.5km/h = 9.6miles/h
Distance
I took the router in to a big field. I could connect with my laptop up to 500m away (at 1Mb). After that distance, I could no longer connect. The alternative firmware (OpenWRT) allows you to increase the output power. I tried modifying this value, but it made no difference at all to the distance I was able to connect to it. Perhaps my laptop (Dell Inspiron 6000) which has always had good wifi connectivity (better than my friend's 6400), may be the limiting factor.
Data Rates
Control Signals: 3.5KB/s
Camera: 50-190KB/s
The camera used more/less bandwidth depending on how much light was in the image. If there was lots of light, it would use more bandwidth.
If the car was to be driven from very far away, the router would continually negotiate a lower speed until it reached 1Mb (megabit). At this speed, the camera wouldn't be able to send back data, but the control signals would still be working.
Power Measurements
I noticed whenever the current changed during car bootup and noted the time. The measurements were done on the battery side before the voltage was dropped down to whatever voltage the device needed. Measurements were taken when the batteries had been used for about 10 minutes and V=15.3V. Since the current was measured here, the current going in to the device at a lower voltage would be higher. All measurements were completed with a Fluke 187 True RMS Multimeter. The last measurement noted was when the device reached a steady-state.

Note: The driving measurements aren't as accurate because it's hard to read the multiemeter while holding a laptop to drive the car and running down the street after the car. heh. Those numbers are accurate +/- 0.1A.
Steering takes very little power. Once the wiper circuit detects that the wheels have turned, it stops turning them. This happens in < 1 second.
Its been my experience that the batteries last for about 1.5hrs under normal use.
Temperature / Over Heating
From the above power measurements we can see that the transistors are driving over 7A @ 12V when accelerating. They're rated for 5A, so they get pretty warm.
The transistor temperature after 25 mins of use indoors (hence lots of accelerating from starting and stopping and not going at max speed very often) was 89°C. The motor was also getting pretty warm at 85°C. When running the car outside, it doesn't seem to get near as hot. Probably because you're driving at a constant speed more often than inside. The transistors are rated for up to 150°C, so I think we're ok. I don't have any information on the motor though.

Hi,
I have question about battery, I would to buy something like this http://www.ebay.com/itm/DC-12V-6500MA-9V-8500MA-5V-15000MA-Rechargeable-Li-ion-Battery-Pack-for-CCTV-Cam-/390493828428?pt=AU_Electronics_Batteries_Chargers&hash=item5aeb3ef54c#shId...It is good decision?...I want to power Arduino,Router and IP camera via this, but how many hours can I get it?..I guess maybe about 1,5Hours or less because IP camera need about 2A, or I can buy another battery 1 for IP camera and 2 for arduino,router. For first I have plan with raspberry pi and USB camera but stream was low and rapsberry cosumes so much too. How is your opinion?..Thanks for answer Seky

Witch version of dd-wrt is used for WRT54GL v1.1, to make carserver work?
Is for this installation the sd card necessary?
Thanks
Posted by Japy on 2013-05-16 @ 14:20
@Hriday
I would suggest you use DD-WRT firmware instead of OpenWRT which I used and then use their web gui to set carserver to start automatically. You can google your questions on DD-WRT as it is well documented.
@Others
If you want to have a conversation about your project, send me an email instead of posting comments.

Hi Jon
what do you mean by this? Run the command 'top' on the router to see if carserver is running. can you show some screen shot so we can clearify the problem thanks :)
Posted by Melvin on 2013-05-2 @ 08:05
Hi Jon,
Me and Hriday have the same problem. How can I enable the carserver? It also shows an error "Socket error 10061:conection forcefuly rejected" and tested the "top" command using SSH and I didnt see the carserver. How to enable it? I've completely followed all your instruction. BTW I'am using wrt54g v3.1 linksys router. But it is same as with the wrt54gl router
Thanks
"@Hriday
If you can ping the router from the computer you're running the VB client from, then it sounds like carserver isn't running on the router.
Run the command 'top' on the router to see if carserver is running."

Use DD-WRT instead and you can edit the startup using the web gui. apt-get commands will still work.

Hi John, I am working on this innovation of yours using C# 2010. Until yet everything is working fine but i needed to ask
Do i have to use the following lines to
"/etc/init.d/custom-user-startup
to make the serial port work on start-up and have the CarServer automatically start.
/usr/sbin/setserial /dev/tts/1 irq 3
/usr/sbin/stty -F /dev/tts/1 raw speed 9600
/bin/carserver &"
or i can manually run the Carserver program in the router by using an SSH client? will it run. I ll make it to start at boot time later

Posted by Senou Natsuru on 2012-10-14 @ 00:13
@ Michael
If you want to get rid of the router, I would suggest using a Raspberry Pi and an Arduino for the IO functionality. Then you can also use a USB webcam instead of the expensive network camera. This means Linux configuration instead of modifying a router.
If you haven't done anything with microcontrollers, I would suggest starting with another project to get up to speed.
Using an ethernet shield and a wifi shield would be turning the Arduino into a router. It would be difficult (at best) to do this. Wifi shields are also quite expensive, so I would suggest avoiding them.
All the best with your project.
Posted by Jon on 2012-10-12 @ 13:06
I was looking for a project to do when I came across your wifi robot. I was thinking about using an Arduino micro controller with mine, along with some shields. I haven't really done anything on my own with micro controllers before, and I had a question. I found another project that uses a WiShield to send / receive the wifi signal. I am not sure if you have much expire nice with Arduino, but I was wondering if I could use the Ethernet shield for the network camera and then code it to send the feed through the WiShield. I have tried looking around the net to find an answer but no luck so far. I was thinking that I could just eliminate the router. Any help would be greatly appreciated. I sent you an email earlier but I did not see the comment section here.

Carserver will not run on another router. You would need to modify the Arduino code to have that functionality.
The VB Client would work the same with no modifications required.

This project was designed around the WRT54GL as it is very hackable. Buy it online? It's still being produced.
You can do this project using any router if you use an Arduino ethernet shield and update the Arduino software.

while you reply sir, i keep my doing my research :p. I converted the hexa value on paper to find the equivalent keys when the if statement gets true and executed.
&HC OR H1C gives H1C then
Output = HC - 8 = H4 or H1C - 8 = H14
H4 and H14 are middles mouse button and H14 is Capslock key. same is the case for H3 or H13 they are CTRL key and left mouse button. Due to this i am confused but i think i am assuming this wrong When sending the output over socket i can not understand what this logical implementation is meant for
Posted by mobby on 2012-08-11 @ 13:21
yes, sorry if i was not clear in my last query.
You have used A or left, W or Up, S or Down and D or Right arrow keys for controling the robot.
I will be using Numpad keys. In the MotionExecutor method, the keycodes
&HC or 0xc = clear
&H1C or 0x1c = IME convert
&H13 or 0x13 = Pause and
&H3 or 0x3 = Control Break
i can not understand the coding. kindly if you can explain
Posted by mobby on 2012-08-11 @ 12:36
If I remember VB6 correctly, &HC is the same as 0xC.

i am writing the vb code in C#.Net4 for integrating the video and controls on the same form. In the method Motion Executor please tell me what these lines does. especially &HC, &H1C, &H13 and &H3
Rem vbOut address, output
'sock.SendData output & Chr(0)
If sock.State = sckConnected Then
If output = &HC Or output = &H1C Then output = output - 8
If output = &H3 Or output = &H13 Then output = output - 2

If you can ping the router from your computer, then it sounds like carserver may not be running on the router. Telnet or SSH in and run 'top' to make sure it's running.

Hi John,
I really need your help with VB program. I use my own robot firmware, so I modify the VB code in the following way. When I press button (ex: w), the program will send character "w" to router. However, I am not good at programming, so could you please check the code for me?
If KeyCode = vbKeyUp Or KeyCode = vbKeyW Then: cmd_up.BackColor = &HC0C0C0: Output = 119
If sock.State = sckConnected Then
sock.SendData Chr(Output)
or I should write sock.SenData "w" instead without output=119

I found a cheap 7" android tablet with usb port for $79. I wonder how difficult it would be to use this instead of a linksys Router. I can straight away see a lot of advantages.
1. Tablet is self powered (4 hrs atleast).
2. Android Tablet can either become an WiFi AP or connect to existing AP/Laptop(wkg as an AP/Connectify).
3. Much lighter than linksys router.
4. Possibility of storing video locally too
5. Has inbuilt camera and mike.(I can even call it thru skype!!!)
6. with optional 3g version of tablet at$99.. I can even operate it from anywhere in the world(taking care of lag)
7. Multiple video codecs to choose from depending on bandwidth.
8. An app can take care of a variety of issues which would be lot simpler to program than a microcontroller.
9. I have added advantage of various sensors built into the tablet. (Ambient Light Sensor, Gyro/Tilt Sensor, Camera, Compass).
Should be worth a try?

hi...I found your project very interesting... I am doing my final year project on it but little bit more enhancement.
1-I am using 3G router with static IP to connect over the internet. Router has its own wifi range too, so a user can connect using wifi or using 3g ip address to connect remotely over internet.
2- I am using PTZ IP CAMERA connect with 3G router so that there would be no need to write an extra application for controlling.
3- Ptz motor wires directly connected to CAR MICROCONTROLLER for let right up down controlling.
4- GSM/GPS/GPRS kit is include to track the real time location, on off the device using sms, call etc.
5-Live audio video streaming using 3g usb modem and also on phone call.
Is there any other thing need for enhance it??

You will use the JP2 connection, the one with 10 holes for the serial ports.
John
Posted by John on 2012-05-13 @ 18:45
On the router connectivity it refers to JP2 in the beginning, but the schematic shows JP2.
Can you please assist?
Thank you,

Posted by Marc on 2012-05-13 @ 15:35
Very interesting. I wonder if there is potential for this to work using a Raspberry Pi (B version) instead of the linksys, and using one USB port to connect a wifi dongle and the other USB port to connect a USB web camera.

It may be possible to do software PWM on a GPIO pin. However, the code would need to change a lot. It's much easier to use a microcontroller that has these features built into the hardware. Arduino has a bunch of libraries for PWM control.
Posted by Jon on 2012-03-21 @ 21:14
Okay, last question from me (hopefully), regarding the hardware:
Is there any way I could skip the need for a microcontroller, perhaps interfacing directly from the router to the steer and throttle servo PWMs? If so, would I need to change anything in the code?

The wifi robot GUI client was based on the pc controlled rc car software. I guess I didn't go through and remove all the references to parallel port in the source code comments. No parallel port is used in this project.
Posted by Jon on 2012-03-8 @ 10:04
Sir,
I appreciate your reply very much on my last query post. I have been through the Visual Basic code that you provided (thank you again for such open-minded view in sharing your knowledge) for the GUI of this system just out of curiosity. However I seem to have a confusion there.
I have seen you mention about the 'parallel port' frequently as a code comment. I am not sure about any use of parallel port in this wifi robot system. I have had delightful success in building the PC controlled RC project where you had used the parallel port but in this case we are using a router, no? Could you please take a while to clear my confusion..? Maybe I have confusion about interfacing the Wrt54Gl (how that is connected to the PC, i understand the hardware modifications, just a little blurry on the connection to PC side).
I would really appreciate your help :)

1. The network camera is the easiest part of this project. Any network camera will do.
2. That will depend on your network setup. If you have the router acting like an access point, just connect the camera directly in your browser.
Good luck with your project!
Posted by Jon on 2012-02-26 @ 09:48
I've successfully set up most of it and it works, except for the network camera part. I am not sure as to how I am going to install this.
1. Would ANY network camera work (adjusting voltage rail as required)? I don't seem to find this particular Panasonic model.
2. To view the video feed in my computer (browser), why am I using my camera's IP directly, when it is connected via the router?
Posted by TZR on 2012-02-26 @ 08:59

Posted by bradhawk on 2012-02-26 @ 03:21
Wonderful project idea and nice, detailed analysis of everything of which I was thinking. Interesting to see that a radio power increase didn't change the open space range though I imagine it would assist with RF penetration when behind objects.

For you who like to add extra sensors like current, voltage, temperature try having a look at OWFS and 1-wire sensors from former Dallas. Precompiled packages for openwrt are available and works out of the box over IP.
Posted by Mikael on 2012-02-9 @ 17:32
@ceazar
The source code for all components are available, so you can implement that feature. However, you'll have to figure out how to implement it yourself.
The electrotech-online.com forum is a good resource you can use.

Good day Sir Jon,
I just want to ask if how i can transmit a data back to the VB app or to PC?", we just like to add a battery sensor that could read how much voltage was remaining at the battery and display it in the VB app.

Backfire will probably work. However, I would recommend a recent version of dd-wrt since it now has ipkg support and the serial port is already configured.

Got it working after a month. Turned out to be a short between RX and TX lines. Nothing could be seen with eyes, but multimeter found it (although I had tested it before).
It's always the unlikely and simplest problems.
Posted by Kristian on 2012-02-3 @ 13:30
@HUNG
Can you ping the router from the PC you are running wifi_robot_client on?
If you can ping the router AND carserver is running on the router, you should be able to connect.
You may need to update config.txt with a different IP if your router IP is different than mine.
Either carserver isn't running, you're connecting to the wrong IP, or you have a weird network configuration that is blocking port 1500 (unlikely).
Good luck with your project.
Jon

Hi,
I'm an engineering student. I have built the schematics, shouldn't have any problems there, but getting the serial port working is causing me a headache (the console port works).
I'm using DD-WRT newest standard version, all OPEN-WRT versions caused numerous problems, at one point my router was almost bricked. I tried using carserver and ser2net, but nothing (jffs is enabled of course). The wifi_robot connects, but the red light stays on, and green light never comes on. What I'm trying to say is that, if someone has got this working and is using DD-WRT send me an e-mail (kristiannuut@hotmail.com).
If anyone is having problems with the schematics then you could e-mail me, I'm sure I could help somehow.
I have, linksys WRT54GS v1.0, DD-WRT v24 standard, PIC16F628A.

Piggybacking off of Andrews comments below, I am working with the new Arduino boards and will probably work on ver 2.0 after I get the initial prototype working. One ? tho Jon, have you heard of anyone having ported your vb6.0 code to objective C/C++ for the Mac? I'm already moving that way but also trying to avoid duplicate efforts. Thanks for the great work and projects BTW!
Posted by Bruno on 2011-12-28 @ 20:43
This is a fantastic read, I have intentions on doing something very similar in the next couple of days. But I can't help notice that using a serial cable to modify the router isn't necessary at all. With the new Arduino Uno boards you can add an ethernet shield and plug the Arduino into an existing ethernet port. Then set up a simple server that will relay commands between the Arduino and your computer. It would be awesome if you could do a v2.0 edition using the ethernet interfaces instead of serial.

good day sir! just wanna say good job for all this cool stuffs here, can't wait to make our own wifi robot, a quadcopter.
but we got problems with our linksys WRT54GL router,(we're all clueless in router configuration)
after installing a OpenWRT white russian v 0.9, we tried to install ur already compiled car_server code (we need transmissions from GUI to arduino, so i thought it's much better to use your own code temporarily), but after the wget command, it says that
unknown host jbvprojects.net
can you explain what's happening here? btw we use Putty program to access the router thru SSH, im using an Windows XP laptop, thanks and god bless! :)
Posted by ajie lara on 2011-12-14 @ 07:25
@Vale
The router is in bridge or client mode to connect to another network. Most of the time I don't want to drive it from over the internet, so it is just an AP (access point) that I connect to with my laptop. You do not need an internet connection to drive it locally.
@Daniel
Newer versions of DD-WRT can install the carserver ipkg file I posted without any special hacks as long as JFS (file system) is enabled.
You'll have to see if you can add a serial port to your v5. I'm not familiar with the hardware differences.
Posted by Jon on 2011-12-13 @ 18:03
Excellent work! I'm from Ecuador, and chose to work with your project to improve it and need some advice. First, I have a WRT54G v5 router flashed with dd-wrt micro. The OpenWRT is not an option due to memory size. How can I install your server on this system and make the same DB9 modification to the router? I'm a begginer with router hacking so no experience whatsoever with micro linux versions. Can you also post some detailed explanations of the VB Client?

Hey man you did a really great job! I'm new to WiFi controlled robots, and i have a couple of questions:
How do you go to connect the router to a network? Is it a bridge connection? or Using Ad-Hoc?
This the part i don't understand quite yet. Do you need to have an internet connectivity? Thanks in advance! really looking forward for your reply.

i have 2 question
1-how to connect arduino to car microcontroller?
2-i want a cheap network camera where can i find it>
Posted by zhiran on 2011-11-15 @ 10:34
I'm very curious about making this. I haven't really built things like this in the past but I've wanted to make a robot that can be controlled over the internet (no matter how far I am from it).
Is there a way to modify this to be controlled from a browser?

@ Zhiran
Yes you can. Read the datasheet for information like this.

hey.. i was reading the data here, n i have a few doubts that have come up....
firstly... i dont see any reference to a network ic, such as enc28j60 or the like.... im not sure how the system is assigned an ip in your case.
Secondly, why a network camera? is it possible to do the same with a mcam?
il ask a few more as and when i encounter them :)

i nearly done it...my serial ports on router are working fine.Source code for pic is also working fine as i checked in simulator,but still i am having problem in getting o/p.
my red led flashes immediately but green led never flash even after i am able to connect with vb client.
Is there any error in carserver in sending string "jbpro" to microcontroller .i use this string for invoking pic in simulator..after that only RB7 pin (green led) glows.
Any help or suggestions please???
you can contact me at "anoop_sheokand@yahoo.co.in"

@Austin: Yeah, I understand that, I was just pointing out that in JB's paragraph, he said "The 9.6V rail," rather than the 9.2V rail. Sorry for the confusion.
Posted by Will Floyd-Jones on 2011-04-16 @ 07:35
@Will... :-)
It's no typo...
12v - 4*(0.7v)= 9.2V
[0.7v = drop across a diode]
Posted by Austin on 2011-04-15 @ 21:36
I just wanted to point out a type-o in the first sentence of the Power Rails Section. "The 9.6V rail was powered by putting 4 diodes in series with the 7812 12V rail." - Shouldn't that be "The 9.2V rail" instead? Great project anyway; I thought it was very innovative!

Posted by sudeep on 2011-04-7 @ 04:35
Really nice work, i've been wanting to do something like this for a while now. I do have a question though,is a router the only way of connecting to the wifi robot both over the internet and with wireless or are there any alternative kits/small computers that can be used (and could support a network camera). Ideally I want to do something a lot smaller and that router would be a bit too big. I know you can get small cards like Xbee Pro that send/recieve wireless data but i'm not sure how the vb app works exactly
Any information on a possibly smaller solution (even if very expensive) would be greatly apreciated. Thankyou.

Posted by nathan chadwick on 2011-03-29 @ 08:20
this is a really cool project. im a little foggy on the microcontroller stuff (my education has not reached that level yet, but im learning). i was wondering if you would be able to think about doing a rc plane like this. i know the hardware you used would be overwhelmingly heavy to a normal rc plane, but ive been designing airsoft equipment and modifications for existing equipment and i was wondering about a compressed air proppelled missile with guiding fins so it doesnt roll out of controll. as fast as this thing would go it would be out of conventional radio controll range in seconds, but if you would be able to think about creating and posting a system that would work with this type of a aircraft (and maybe prototype the aircraft to test it on) i would be very excited to see that work.
Posted by nathan chadwick on 2011-03-29 @ 08:16
Do you can implement this project by router model Linkys 120N
because i can't found the Linksys WRT54GL in the market

Dear Jon,
I found very useful information here. First I thought to buy a Spykee bot but then I saw your website. My plan is to build a robot with a coordinate measuring system so that the bot can dock into a power unit automatically. - Do you have some good hints about such devices that can measure where the robot position is ?
Sure in the beginning I can make a visual docking system where the user can dock its robot to a power supply manually. - But later I will need coordinates.
Sincerely : Pavle Dukanovic
P.S. That is a lot of work.

Do you think is it hard to use standard camera with Eye-Fi wireless SD Card to transmit video. Eye-Fi has range 90 feet, so it should be conected to the router and transmit the video through router. New c code for carserver should be written, right? I.m good at c, c++, Visual studio programming, do you have any hints for me :) Thank you very much

From the comments, I see that many people are having trouble editing the custom-user-startup. I also did not find such a file, but created one using 'vi' command. But that too did not get my carserver start at boot(though my baud rate is always 9600 as set in the file). What i do is, i login using putty everytime and then type 'carserver' at the console. The 'carserver' starts and you can see on the console the hex value sent to the router .
Posted by Aju Krishnan on 2011-02-8 @ 07:11
Dear Jon,
I am doing the Wifi-Robot as my final year project. I have completed the OpenWRT burning and installing carserver. I can communicate to the router successfully. I have only PIC16F877 and have written the serial interfacing program using the mikroC compiler and its inbuilt UART library. But its not working. I tried to see the waveform on the serial port in CRO. It swings from 0 to 3.3V instead of -3.3V to +3.3V . And my MAX232 output waveform is in the inverted form from the actual expected serial waveform(5V in the idle case and 0V when that particular bit arrives). Is there any problem with the serial port on my router?

It was fun making this project... I my own car based on this and it's working perfectly now...
I used a 89c51 for the microcontroller and a Zavio ip camera instead of Panasonic's since it's not available here in India...
It was a pain to get the VB program working in Windows7 but I did manage it eventually... and I have tried upgrading the VB client to .NET VB 2008, it didn't come out too well as I had to do all the programming again... trying to get the carserver in the router to accept data from .NET VB was terrible finally datatype int16 worked...
Later I moved on to connecting the camera feed to MATLAB and do some image processing to control the robot autonomously.. It now almost follows a red object on it's own..
Thanks a lot... and to the people trying to do this... you will learn a lot on the way to making this work.. good luck..

@pedrodv
No. A single I/O pin doesn't have enough power to power a fan. You'll have to use a transistor circuit. There are many arduino projects that do similar things. Google around.

Hi Jon. I've purchased all parts required to do this project, however I've ordered this: http://www.nuelectronics.com/estore/index.php?main_page=product_info&cPath=1&products_id=14
As the micro controller. Can you please tell me if this is correct and I don't need anything else to make the microcontroller work?
The only thing I've not ordered is diodes for the step down in voltage so boards don't fry.
If possible is it possible for you to provide me a simple wiring diagram for the complete project, where the diodes are etc as this would be great help for a beginner ;)
Reference the USB arduirno I've seen on eBay arduiron USB to serial adaptors for sale so one of them I'll be trying after I've tried one I've already ordered.
Cheers

I have already built this car using the micro-controller and max232 and all works great. I am now trying to build another but using a usb Arduino. I see in this comment section that several people have stated that comments made about the voltage divider are wrong. I am wondering if anyone has got it to work with the usb Arduino and how they wired the divider.
I will keep looking here to see your comments.
Thanks ... John

>> "was curious...what sort of delay off of real time"
The delay (I'm estimating) is about 250ms for the video feed, but effectively instant for the control signals to be sent across.
It's quite usable, but not perfect. I bought the cheapest network camera I could find. If I were to do it again I'd get one with pan/tilt capability and also try to find one with lower latency.

Hi. Great project.
If it will be limited only to management of car instead of a router it is possible to use IP camera with PZL. And instead of PZL to establish the car.
Then it will be simple to provide the WEB-interface.

Posted by jonuel on 2010-12-19 @ 16:50
If I might help here.
This is what I did and all works good.
First look above at the diagram, "Pin Assignment Reciever", this is the pinout for the RX2 Chip that is inside your car.
You will see pins that are labeled ...
Forward-Backward-Right-Left.
Solder a wire to each one of these pins, be very careful and do it as fast as you can and try not to get the chip too hot.
These wires will then go to the "Microcontroller Circuit" (in the diagram above) and contect to the corresponding pins, forward-backward-right-left (2-1-17-18). I used a 4 pin plug here, male and female.
Make sure you give yourself enough wire length for construction later on.
Thats it!
Hope I helped you some.

Correction to post below ... sry.
I am having a problem with the Robot.
I drive the Robot for about 1-2 minutes and then it shuts down.
The circuit seems to lose power.
I look at the router and camera and the lights are no longer on.
I then recieve a error from the "WiFi Robot Controller software".
Error:
Socket Error 10053
Connection is aborted due to timeout or other failure.
I unplug and replug the power to the circuit and all works well again for another 1-2 minutes at which time it happens again.
More info: This happens with or without the camera connected.
Any suggestions?

I unplug and replug the power to the router and all works well again for another 1-2 minutes at which time it happens again.
More info: This also shuts the Camera down and this happens with or without the camera connected.
Any suggestions?

The one I used had an atmega168 in it.
Try posting your question on an arduino forum. I don't know what has changed between the two microcontrollers and how they're programmed.

Hi. I wan't to make a similar robot and need a little help. My project is a wifi controlled gun mount with camera and lot of image processing. I know how to do image processing but don't know anything about linux and network programming. For image processing I'll probably be using OpenCV(a C++ library) or else MATLAB
Can someone please explain to me the purpose of each part of program?
first of all why do we need to replace linux with Open-WRT ?
What is the purpose of CarServer ?
How does the router send its packets to serial port ?
My other option is to use 2 laptops. Data sent from one latptop to other through wifi which manipulates the data and issues control signals through serial port. But I want to avoid using 2 computers.
Please help anyone

The wifi robot control software is written for Windows. The router runs linux. You won't find a router running windows.

Press 't' to connect.
As long as the carserver software is running on the router and you can ping it, the vb client will connect.
Posted by Jon on 2010-08-10 @ 22:28
When I start the WiFi Client software in the box next to the arrows it states "NOT sending data".
I have a cable to the router, not wireless. I can ping the router and go online. Wondering why it's not sending the data. At this point I'm not sure were to look for the problem. Any help I would be grateful for.
Thanks
Posted by John on 2010-08-10 @ 22:15
You can just download the compiled version if you just want to use it. You don't need to compile it yourself.
However, to compile it yourself...
From the article:
You'll need to download the OpenWRT SDK (Linux Only) and follow this guide for compiling software: Eric Bishop's Writing and Compiling A Simple Program for OpenWRT (just follow Part I) <http://gargoyle-router.com/old-openwrt-coding.html>
Please read the article carefully. There is a lot of information there.
Posted by Jon on 2010-07-28 @ 23:12
Thanks. I'll go give it a try.
another thing. i tried compiling the carserver but it keeps looking for the carserver.o. why is that?
Posted by Benedicere on 2010-07-28 @ 21:02
Use X-WRT v0.9 instead on the router instead. I haven't tried it with any other versions.

Hi Jon,
I am new to Linux system. I am using ubuntu 9.10. My router's firmware is Openwrt backfire 10.03. How will i compile the carserver? Here is the output when i tried to install your carserver.c:

I used 0.1uF capacitors. That was recommended in the datasheet for the MAX232A. Different variations of the chip will recommend different values of capacitors, so check the datasheet for your particular chip.

@Huub
The wifi robot client is trying to connect to the carserver program on the router. The carserver program must be running on the router (see instructions for getting it to start automatically) and you must be able to connect to the router (i.e., be able to ping it). For testing, I would recommend you connect to the router using an Ethernet cable.
If the carserver program is running on the router and you can connect to it, the wifi robot client (VB App) will be able to talk to it and you won't get that error.

Hi jon,
thanks for the great project and the great documents.
i have reached the last step now , but when ever i try to connect to the router using the vb6 program i get socket error 10061:connection is forcefully rejected.
i checked my antivirus and firewall , and even disabled them.
nothing seems to change.
what could be the problem?
is there a way to figure if the car-server is working probably ?

Hi there,
I'm trying to build a "3grobot" with a portable 3g router, so the car can be operated from a 3g connection. At the present I have a wifi webcam connected to a portable 3g router. After connecting to the Internet the 3g router updates it's ip (dyndns) and I can operate the ptz camera by accessing it's web interface.
Do you think you could make a v2 of this tutorial with a 3g router instead of the dlink router?
This is probably way out of this topic but I've found a portable linux box at http://www.korenix.com/jetbox-industrial-communication-computer-8152-overview.html, they're quite expensive at the present, MSRP: $975.00 at http://www.industrialdirect.com/JETBOX8152_p/jetbox8152.htm, but I imagine that's probably very easy to connect the 3g modem/3g router or any serial/usb device to this box and operate the car, camera or any other devices from a web interface.
Korenix.com also has cheaper models for lower prices and they're probably enough for this type of project. It would also be nice to have some sort of gps tracking device installed, with 3g we can control the car from long distances and we don't want to loose it.
A playstation gamepad to control the car would be 5 starts, (I'm probably asking too much!).
I'm not sure if you have the time, will or resources to build a project with the characteristics above, if you have, it would be a huge upgrade to this project.
regards,
Lobito

I'm having a problem understanding how the linksys hooks up to the steering and drive portion of the car. Where do they hook up to each other? Is the max or PIC needed if you don't plan on hooking the serial port to the linksys? Is there a simpler way to interface between the linksys and controls of the car?
Thanks

Would it be easier to replace "carserver.c" with "ser2net" so that you don't have to hardcode /dev/tts/1 and it would be more compatible with any OpenWrt supported router? ser2net could be found in the OpenWrt packages.
Edit /etc/init.d/setserial
Code:
#!/bin/sh /etc/rc.common
# Copyright (C) 2006 OpenWrt.org
START=15
boot() {
/usr/sbin/setserial /dev/tts/1 irq 3
/bin/stty -F /dev/tts/1 speed 9600 raw
/usr/sbin/ser2net -u &
}
Edit /etc/ser2net.conf
Code:
# <TCP port>:<state>:<timeout>:<device>:<options>
1500:raw:3600:/dev/tts/1:9600 NONE 1STOPBIT 8DATABITS -XONXOFF LOCAL -RTSCTS
Anybody can easily replace /dev/tts/1 with /dev/ttyS0 for Atheros-based routers.
"stty" could be found in the OpenWrt "coreutils" package. Just run 7-Zip to extract it and upload to your router. But I think "ser2net" already took care of the serial port.
BTW, this is a great project.

@Jon, Jim: I'm a bit confused by the voltage divider to hook up an Arduino to the serial port. Shouldn't it be the other way round:
GND - 10k - WRT RX
Arduino TX - 10k - 10k - WRT RX
The way you drew it, only 1/3 of the Arduino's voltage will reach the WRT (i.e. 5V/3 = 1,7V). The other way round (as above), 2/3 of the voltage reaches the WRT (3,3V).
Or am I being totally stupid here?
Posted by Björn Giesler on 2010-02-4 @ 03:59
Hi Jon,
this is great. I want to do the same, but i don't know where to get such a car with a Realtek RX2/TX2 chips or a pin-compatible alternative. In germany we don't have thrift stores where i could find that cheap cars. they must not be that cheap but should have appropriate chips. could you provide more data about the cars, so i could google for them. maybe i can find them here.

We also are going to pull-up the DTR pin to +9V. With this quick hardware modification, it basically adds a program-locked mode so that new code can't be uploaded and the microcontroller can't be reset by the serial port. If you need to reprogram it, just flip the switch. +9V is a pin with easy access on the Freeduino MaxSerial.

Jon, i am thinking to build this project.
Can you please attach the circuit diagram and the code used to develop this using the ATmega168.

Your project is very interesting! I am a undergraduate. At present, I have applied your project to my study by taking PIC16f628a and a file (files ถ้ามีหลายตัวน่ะ) which you suggested on website in order to test PIC16f628a. Then I put the program into it and tested in hypertiminal that was showed PIC16f628 alive; however the hypertiminal showed unreadable language.
Therefore, I would
would like you to suggest me to how to set the hypertiminal.

Hello Jon,
I'd like to use this project as a sort of reference for one me and my team are building, mostly since at the start many of our ideas came from this page, which we are very thankful for. If you have a problem with this, please e-mail me and notify me of any concerns.
Once again, thank you for the ideas.

im very impressed with ur project...
i would like to know is it to costly for me to build dis kind of robot...
how much is the cost...
can i use the infrared red cctv for the camera..
please reply...
Posted by azrol on 2009-11-27 @ 07:28
ok, makes sense for the most part, but i dont get how you can just connect to the router. Does the router just Emit the wireless signal, or does it get it from somewhere else? Im confused.
Posted by Michael on 2009-11-23 @ 15:10
Hi jon,
thanks for the great project and the great documents.
i have reached the last step now , but when ever i try to connect to the router using the vb6 program i get socket error 10061:connection is forcefully rejected.
i checked my antivirus and firewall , and even disabled them.
nothing seems to change.
what could be the problem?
is there a way to figure if the car-server is working probably ?
yours
Posted by david on 2009-11-15 @ 15:40
Great job. I noticed a lot of people in the comments had requested more detailed information (or documentation) on building the project, and I was wondering, if such information exisited, if you could send it to me as well. That would be very much appreciated, as I'm very much looking forward to doing this project.
Kind regards,

Hi Jon,
Thanks for putting this page together and explaining everything in such methodical, logical detail. I'm considering doing a similar project, though I am constrained by lack of money. I do have a lot of hardware around though: most of it getting old now. I think I might use an old PDA (Sharp Zaurus SL-5500?) instead of WRT54GL, though I have one of those as well. The current drain of a PDA is fairly large, compared to a WRT, and I'd need a camera as well. I have a camera CF card and could use that. Also, I might use a Bluetooth Arduino, if I can only get the hang of uploading programs to it (it is really picky about when it will accept code). I found this site after typing 'wifi robot', having seen the Rovio Wi-Fi robot in a catalogue. I was totally shocked at how expensive the Rovio is, and I am determined to do this myself and save money/re-use my junk. Thanks! Lex

Maybe in version '2.0' of this wifi robot, you can use a Fonera 2.0 router (www.fon.com). Fon has a smaller form factor, low in power consumption, USB webcam support, apps, but also USB GPRS/UMTS/EDGE/HSDPA stick support. Only a solar panel is missing to recharge the batteries :-)

I am really new too all this, but I did find a build of OpenWRT 0.9 on http://x-wrt.org/ that has the custom-user-startup.
Note that it will not show up in the ssh directories until you actually add something in the web GUI to the startup file.
Hope that helps!

Jon, if you;
ddwrt a new router. Set it to repeater bridge mode and connect to the car through that router.
Add the netgear 7dbi antennas (2set, $15ea ebay) to both routers.
You'll get a MUCH larger driving distance.
With the new router you could connect a directional antenna for theoretically miles of coverage.

Note: If you're using a usb version of the Arduino, you may be able to just connect the RX & TX pins to a MAX232A and then to the router serial port and may not need this modification. I only have the MaxSerial version, so I can't verify either way.
I have made a usb arduino decimila into max 232
but it is not work,when i test the tx port ,it was work,only rx no work,and show me
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
i think is it arduino bootloader don't give port to my max232,can u help?give me some advices?

Jon and Jim:
Thanks for all the helpful information you have posted. My partner and I are embarking on attempting to build this cool little car. We'll be using the USB Arduino, and from what I can garner here, there are two methods:
1) Arduino RX/TX to Serial Male on Linksys Router VIA MAX232A -> Serial Female
2) Arduino RX/TX to Serial Male on Linksys Router VIA 3 10k resistors (as Jim suggests)
Is this correct? Any other hints from anyone who has done it with the USB Arduino board?
Thanks very much! Really enjoyed your video example...
Posted by Sue on 2008-12-21 @ 19:02
This looks awesome, but could you go more in depth on how you are able to control the car with the micro controller, like what pins go to what? And, I looked up and have read a great deal about the router, but was unable to find out how to get the TTS/1 COM port, or whatever port needed, wired to the router.
Another idea, I have a couple old laptops that don't have screens, and their keyboards are well not in great shape, lol but in 8th grade I used one to make a "robot car" it had a webcam and everything. I used the parallel port, and attempted to use your Computer controlled RC car design and modify it so it would turn relays on and off which in return would turn 12vdc drills on and off... That was unsucessful, but I had head lights, a siren, and webcam that all worked. I am still not totally sure what I was trying to do was actually possible...
But, lol I am going to attempt this but instead of the network cam and router, I am going to use one of those laptops, and run everything into the computer there. I'd just connect a usb webcam, wire everything through i guess that micro-controller and use vnc or remote desktop connection to "wirelessly" connect to the laptop on the car.
Thought that might bring some ideas for other projects.
Also, if you can possibly help with the interfacing between the computer and the RC car's board or say a series of relays, please help lol.
Thanks.

hi, i was reading the proyect and it is very amazing what you have done, i was wondering if you can send me more info or help me to built one as yours. may be some electronics diagrams and a little more explanation connecting the router to the pic and the RX2. i have already a linksys WRT54GS V7 and a netgear WGR614V2. i dont undesrtand how you send the data to the router and how the router send it to the pic and then to the rx2. so i will waiting your mail with some help to start building my own wireless car
have a great day and again congratulations

@Jessica
Thanks for your comment. In answer to your questions:
1) Yes, the PIC output pins output VCC which is 5V.
2) Yes, the other I/O pins can be used. Note that RB1&RB2 are used for serial communication. Nigel's Pic Tutorials are a good place to learn PIC programming with practical examples (http://www.winpicprog.co.uk/pic_tutorial.htm). There are many other sites on the net that cover basic PIC programming in ASM.
Good luck! E-mail is a better way to reach me if you have more questions.

Jon.
I stumbled upon this project while searching for a way to overclock my WRT54GL. Needless to say it will no longer be serving its intended purpose :)
I have a few question regarding your project
1) Does the PIC output the same voltage as VCC (5V) on the pins that are controlling the movement? I am trying to make a custom H-bridge for it since I have a car with a dead control board. I will be using some transistors to switch to a higher current/voltage.
2) Can I use RA4 - RA7 for additional outputs. How about the other outputs starting with RB*? Do you perhaps know of a guide showing an example of how this can be done(if it IS possible)?
Thanks and AWESOME project!

Good work. You know my favourite part? The inbuilt protection mechanism where if you try to go back and forth or left and right at the same time, you can't. That's so exiting!
This is so great. I guess if you've got a hackable linux router, you gotta do something cool with it. Eh?

@Indu
The camera is a network camera, so it is attached to the router with a normal Ethernet cable.
Posted by Jon on 2008-10-12 @ 23:12
Really nice project!
I think, instead of add ultrabright leds, you most install "near infrared spectrum LEDs" and remove the IR filter from the camera lenses so you could drive the unit even at 0 lux!
Cheers!

Posted by sulaim on 2008-10-7 @ 11:02
Make sure your router is connected to the 'net.
Then (as listed in the article) :
SSH in to your router then ...
# cd /tmp
# wget http://www.jbprojects.net/projects/wifirobot/carserver_1_mipsel.ipk
# ipkg install ./carserver_1_mipsel.ipk
Posted by Jon on 2008-10-3 @ 14:53
I have installed in my WRT54GL dd-WRT software and I need how can I install the "carserver_1_mipsel.ipk"
in this operative system. If I execute the "ipkg install ./carserver_1_mipsel.ipk" sentence it show this message:
ERROR: File not found: /jffs/usr/lib/ipkg/lists/whiterussian
You probably want to run `ipkg update'
Thanks and sorry for my english.

Posted by Evan on 2008-09-24 @ 11:37
Hi, you you post how to wire it all up? and how did you connect the camera to the router I may but the camera and use my router to make it wireless. I have the same one.
Posted by Evan on 2008-09-24 @ 11:29
Hey, nice project!!
For distance you could plug in along the way another router running dd-wrt (of openwrt too) in universal repeater mode. Your signal will be repeated and you will get better coverage. You can also get an external wifi card for your laptop and attach an external router (google pringle can antenna).
Increasing the antenna strength on the router made no difference because your laptop still had its normal low strength and couldn't "talk back" to the router.
If you want to take this to another level you can also hook up a 3G connection (via another openwrt compatible router with a USB port) or via serial, and control your RC car (or RC plane!) via the internet, at that point you can add GPS and what not, hopefully not get arrested.
Cheers!

Hey Jon,
Awesome job, I saw this today over at www.dailywireless.org and now I want to build one! Can you please give some more detailed instructions and schematics on how to put everything together, for anyone into electronics and stuff like this it is pretty straight forward and looks fairly easy but you did not go into much detail or show how the power regulators and the battery wiring is all connected. Could we get a schematic for all of that?
Basically I just don't understand the power connection and the voltages regulators and how t wire all that up, a simple schematic of that and an overall connection diagram would be great.

Only one beef. How about a link to Amazon for the Linksys WRT54G Ultimate Hacking book, instead of a link to a pirated copy to support the authors?

Jim:
Thanks for looking in to it. I had forgotten that they're using different voltage levels.
Your voltage divider circuit looks good.
Posted by Jon on 2008-09-7 @ 21:08
Jon,
Checked out the TX/RX pin connections for the arduino.
This should be the perfect solution for all arduino boards (USB/SERIAL). The voltage for the arduino RX/TX pins D0 and D1 are 5v. The WRT TTL TX/RX pins are 3.3v. 3.3v is sufficient to trip the arduino inputs but the 5v maybe too high for the WRT!
So we need to drop the 5v to ~3.3v for the RX of the WRT. This can be done with a simple voltage divider circuit.
So the connection goes something something like this:
ARDUINO RX - WRT TX Directly wired.
ARD GND - 10k Resistor - 10k Resistor - WRT RX
ARD TX - 10k Resistor - WRT RX
This drops the voltage enough so as to not damage the WRT. (ATTENTION: the RX/TX lines should be disconnected from the ARDUINO before connecting it to a PC via USB or it could fry a few since the ARDUINO uses the same lines for USB connection through the FTDI CHIP!!!!!)
This solution may sound more complicated but actually requires fewer parts (I am all about fewer parts!) only three resistors.
Thanks Jon for all your hard work on this project. Around the first of the year hopefully I will have my Project completed and I will return here with a post to the write-up as well as any changes I make to your source code.
Posted by Jim on 2008-09-5 @ 10:44
Jim:
Yes, connecting the RX and TX pins of the Arduino right to the router RX and TX pins should work. I thought about it, but didn't try it. Since I decided against using the Arduino, I added the tested code I posted to the project afterwards because the microcontroller is so popular.
If you connect them directly, you won't be able to easily connect the router to a PC serial port. It was important for me to have this feature while developing to assist in debugging. By all means, try it out and if it works fine let me know and I'll add the info to this article. I don't see any reason why it shouldn't work.
Pete:
It won't cost much to send them there. I'll get an exact figure early next week and e-mail it to you. I would estimate $5 CAD (about 2 pounds). And yes, I do have Paypal.

Posted by Jon on 2008-09-4 @ 22:36
I have a question. This project is very similiar to one I have been planning for a while. I really like the use of a router for the wireless capabilities of this project (I have now changed the layout of my project based on your work!) Thank you for that.
On to my question. Could you not just directly connect the ttl RX/TX Pins of the router to the Digital Pin 1 and 2 of the Freeduino (which I believe accepts ttl input). I realize you probably used the serial connection because you already had the router hacked for it. For those of us with USB xxxduino boards may find this option easier. That is if the xxxduino board will handle the signals properly.
Sorry for the ramble but you seem to have done quite a few experimentations with openwrt xxxduino control. Just wondered your thoughts.
Posted by Jim on 2008-09-4 @ 19:13
Hey Jon,
Ah many thanks :), btw i'm lovin the project, and hopefully i can build one too haha, i have a little bit of electronics knowledge so hopefully all will go well.
Thumbs up to you tho
How much do you recon it'll cost for the chip and sending it to uk ?
Also do you have paypal ?
Pete
Posted by Peter James on 2008-09-4 @ 09:34
Hi Pete,
I'd be happy to send you a pre-programmed chip. I'll just charge the cost of the chip + cost of shipping.
The MAX232 isn't a programmable chip and can be bought from many major online retailers or as a free sample from http://www.maxim-ic.com/samples/ .
If anyone else wants a pre-programmed chip and the demand isn't too great, I'll be happy to send them for whatever the actual cost is.
Jon
Posted by Jon on 2008-09-4 @ 00:25
Hey there Jon,
I was just wondering if u could sell the chips, PIC16F628A and MAX232A programmed ?
It'll save me time and money buying the programmer for the MAX232A chip ?
Of course i would pay for your labour costs :)
Let me know by email :)

Posted by m4l3_Bug5 on 2008-08-31 @ 09:14
Hi, perhaps you could use a Fonera with freewlan extensions... it's smaller than a Linksys and there are tons of guides to explain how to use the "non used" gpio's on the board to go left/forward/ etc without needing an extra micro controller...
some people allready wrote drivers to controll these gpio's...
an example can be found here :
http://www.youtube.com/watch?v=KACkqpPyNNk
he used the onboard webserver of the fonera
it would be great if one could use a Sony PSP or Nokia Wifi mobile or Nintendo DS to move the car... and have the cam show what's on the road :-)
the webcam can be connected to the "wan" interface of the fonera...
and La fonera could even use an existing wifi station to "uplink" to so it becomes also a wireless mobile accesspoint while you drive it on it's "myplace" interface!

Too bad Tesla's dream of wireless power was squashed by the powers that be years ago. If we had wireless power now we wouldn't have to worry about battery packs, solar panels, etc... Wireless power is making a comeback though, maybe it'll be the norm within 20 years.
Great job, Jon. I have one of these routers so it may be a project I would like to work on and possibly help extend. Thanks for all the great resources!!!

Thank you Roger and Greg for pointing me in the direction of figuring out the web streaming options.
There is a way to get the streaming view in a standard browser, so the Windows software is not required.
I've updated the Camera section of the article with the appropriate commands.
Posted by Jon on 2008-08-28 @ 17:30
wow dude u really inspire me to do this project i was thinking into do the same but im thinking into use a bigger car,add joystick control, a gps system to the project, some solar panels and a wifi card from att. wow congrats its awesome
Posted by mokopato on 2008-08-28 @ 16:16
Jon,
I can't help but wonder if there isn't a configuration issue then...I run several of those cams (exact model) for my business and for a few clients...all have good refresh rates, and no problems with motion. The cam I'm looking at right now is getting about 12fps @ the highest res. and quality. Granted all are over a wired network, but I don't think bandwidth is the issue here. Maybe try the latest vs. of Firefox? (much better scripting speeds)
Posted by greg on 2008-08-28 @ 14:43
The Windows-only software is required to get the streaming view. Yes it runs a webserver, but the refresh rate is VERY slow compared to that of using the software.
I'll investigate whether using 'http://192.168.1.253/SnapshotJPEG?Resolution=640X480' as one poster mentioned produces images at an acceptable refresh rate.
With the software I was able to get around 15FPS.
Posted by Jon on 2008-08-28 @ 14:31
Actually, that particular network cam works just fine in Linux...I'm confused by the writer / posters who say it doesn't. Yes, the cam comes w/ a Windows app that lets you view but of course you don't need that. The cam runs a webserver (as most network cams do) and you can connect and view w/ Firefox on both Windows and Linux systems with no problems.
Just resize your browser window so only the image shows..it can be adjusted for size and res. in the settings.
Posted by greg on 2008-08-28 @ 14:24
Very Nice, I am impressed. Bringing wifi+linux to a project for 70$ is amazing.
if only the IP camera worked in linux... then I would have some interesting ideas.
Posted by Colin on 2008-08-28 @ 12:45
Just wanted to say, Great job Jonathan!
I started in on a similar project using a fon and a PSoC MCU last year, currently waiting on a servo to replace the one that came with the truck, as well as getting the motor driver finalized.
PS: My site detailing my version of the project is at http://zarnochwf1.com/?q=node/13
Posted by Walter on 2008-08-28 @ 11:05
Nice! i may try the same thing with a fon, since its much smaller, and runs the same software, i could pack it all into a tiny box :D
Posted by Derek Vance on 2008-08-28 @ 10:33
Great project! There's a better way to use the camera though. That camera will serve up the current frame as a jpeg with the URL >> http://192.168.1.253/SnapshotJPEG?Resolution=640X480 <<. (use your IP obviously.) It's case sensitive and must match exactly. I shell out HTTPGET to read this URL to a JPEG, and when the JPEG arrives stick it in an image control. It's slower than a stream but better on a slow connection because you can control the frame rate. And you can get the actual image data to do processing.
Posted by Roger Williams on 2008-08-28 @ 10:05
wow! thanks for that great write up. this is exactly the project I have been thinking about and am so glad someone did all the hard work. We are looking at using a boat though to do some water quality sampling so should have similar needs. thanks again.
