I went to the pawn shop today and picked up an old RC car and a robot vacuum for $10 - total. Not a bad deal. I also go an old mouse and a book in that price.
The vacuum uses a bump sensor of some sort, I'm gonna take it apart and figure it all out. The RC car will probably have a brain installed one day. I just need to learn how to do all that first :)
