I have yet to see a remote controlled Arduino Robot! I really would like to make one for this science scholarship.
I would like to make a simple Robot that has four wheels and can turn left, right, forwards, and backwards, using a RC Transmitter.
Would i have to use the Xbee shield? or can i just plug in a receiver and be good? Then i'll really need help with the programming.
Thanks!
One thing you could do is get an RC car and strip it for parts. It's usually possible to tap into the output of the receiver with a bit of fine soldering/trace cutting.
Any tutorials? I would have no clue where to solder what with a reciever.
I know you're able to use the receivers with the Arduinos, it's just a matter of decoding!
But, there's also a very cheap solution to this, you can buy some of the cheap 433 MHZ or 315MHZ RF pairs, which have a range of about 500 feet with just an antenna! (more if you buy the encoder/decoders)

The ones with the encoder/decoder supposedly have a range of about 2km with an antenna, haven't used them but that's crazy distance!
(can't transmit crazy fast, so it's not useful for fast data transfer, but just using it for what you're doing would work)
But anyways, if you're interested in building robots, you have got to check out http://letsmakerobots.com all kinds of uberness! I know there was a robot that uses IR code to do some movements, I just can't find it right now. 
Best of luck!
I am working on a remotely controlled robot! It is remotely controlled by PC, and you give it time, direction, and speed commands.
Looking over what you want to do, you could put an XBee at both ends, and have it setup for analog or digital inputs depending on how the transmitter works (switches or potentiometers).
On the recieving end, have the Xbee output the signals to the Arduino, and then the rest is up to you! You could either build a custom motor controller (like the motor shield, etc) or try to patch into the existing motor controllers.
What would the robot be doing exactly? Anything super cool?
