Remote control cars over the internet? Answered

I came across this site with 2 RC cars that can be controlled freely over the internet.
rajesh.homelinux.org/


I want to make one of these setups, but I don’t know exactly how to do it. I need help with getting clicks from a webpage to a full time pc to some relays or something like that. Also I need some way to embed a live webcam stream into the webpage. I can handle everything else.

I've just got finished with this project. I used an Arduino UNO along with an Ethernet Shield to the control the car over the internet. Here's the URL for anyone interested. The documentation is fairly detailed.

i found on the internet the project of a japanese company about this . here is the link : http://www.jokerracer.com/blog/2009/11/jokerworks-releases-joker-racer-rc-server-the-worlds-first-linux-server-for-rc-cars-to-enable-intern.html.
is an interesting idea that they were thought.

I still need some help with the following...
1. A webpage with buttons to control a program on the host.
2. A program on the host to control a parallel port.

I want the webpage to have 12 buttons, two sets of 6. One to control car 1 and the other for car 2. Each set will have the following keys.
forward,
back,
forward left,
forward right,
back left,
back right.
(Or possibly a set of 6 buttons with a drop down menu to select the car to acontrol.)

I can use ubuntu or Windows, doesn’t matter.

I've been looking around for something similar (to control relays over USB) but everything I find is more expensive than the Arduino.

I got everything external under control. I am going to use the 25 pin printer serial port. The only problem I have is trying to get a client pc on a webpage to communicate with my computer then to it's serial port.

I already know what I’m going to connect to the parallel port.(below)
heres the schematic

I heard you can use Yahoo! to live stream a webcam.

The main thing I want to do is to have a webpage (client) communicate to my fulltime computer (host) and then communicate to a pair of controllers.

The webcam can come last.

For that I wouldn't know, so I just threw in my 2 cents worth.

I found this relay board. with a schematic
http://www.electronickits.com/kit/complete/elec/ck1601.htm

I know that the commands for this on Windows are binary (ex. 0000 0001 opens relay 9, 0010 0000 opens relay 3). I will most likely make one myself and use their software (I dont really need to.) but I don’t know how to control them form a different program let alone from a webpage.  So, basically I am currently stumped on the programming.  I do know some basic programming (Visual Basic, some C, and a bit of basic JAVA).

 Google "computer control external" and you'll get all sorts of useful information.

How can I connect the controller boards to the computer? It has to be able to trip some relays. I was thinking the parallel port but I don’t know it has enough pins. I know some people are connecting LED's to them so it is possible. Also I would prefer to not use the Arduino .

I didn’t make a schematic yet but I know it will use a series of relays, capacitors, diodes, then the RC car controllers, and some other minor stuff.
