Let's Make Robots!

Using PS3 Contollers over Bluetooth

I'm trying to program a robot to drive and perform various functions using a bluetooth device....i can make my own controller with simple buttons to control the robot wirelessly but that doesn't seem nearly as cool. Did a bit of research but couldnt find anything on how to use ps3 or maybe even an xbox controller over bluetooth. Does anyone have any good websites on how to do anything along this line?
