Remote controlled Car?

Hi there,

I'm doing a project for my study and I am currently searching up and down the web to find a project where somebody tried to contoll a remote-controlled car with the arduino board. I haven't found something like this yet, so if anybody has seen something like this or has an idea how to do this, I would be very glad if you could help me.

thx a lot

Here's one example http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1197797322

Another approach: Arduino-powered bluetooth car

(You could do it more neatly, I'm sure. :smiley: )

It probably would be pretty easy to do. You could use a radio transmitter receiver pair from sparkfun.
For the controller two pots 1 controlling a servo for the steering on the car the other controlling the speed of the motor.

I just bought a fully working RC car at a flea market, and I'm planning on hacking the emitter to control the car wirelessly. I think I'll go with programmable resistors to replace the potentiometers on the command. I'll control the resitors via the arduino, with a sketch in processing to send the values (steering and acceleration).
I think I'll use these chips : AD5206 Datasheet and Product Info | Analog Devices

I'll keep you posted.

If you want the arduino to NOT be on the car and send its commands over the radio link, I would suggest this method: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1193927390

It works by feeding a pulse train to the radio which then mixes it with its own commands before putting it on the airwaves, so you can mix Arduino commands and manual input by a driver/pilot. The downside is that it requires a radio with a trainer port, which doesn't have to be expensive, but won't be the case of most all-in-one packages from the toy store... altho in some cases where the transmitter is not monolithic, you might be able to highjack the radio stage and feed it your own pulsetrain with the same code.

If you want the arduino on the car, it might also be possible to do some hijacking, depending on how the receiver on the car is set up. There is an intermediate step in the receiver which reconstitutes the pulse train before demultiplexing out to the various channels (servos/speed controllers/etc...). If that step is available on the car, you could tap into there with the same code.
