Let's Make Robots!

Rom-Bot

I dismantled a cd drive from my old laptop yesterday, and found out that the plastic frame and insides were a pretty good chassis for a robot. It will have an LCD screen, use an IR sensor for not running into walls, and possibly some odds and ends here and there. Does anyone have any suggestions for some of the features that would be integrated into this robot? I am using a Picaxe 28x1.
