50$ robot programming

[Trumpkin]

I have almost completed the 50$ robot microcontroller but I am planning on using it for a different type of robot, something like a room exploring bot that avoids walls using the sharp ir range finder. I know a little bit of C but I dont how to program robots. Does anybody know of any good websites or books that would be good for learning how to program?
