I remember,

When I was partners with my good friend Shia-ma(guy in picture) in robotics and he made a tiny tank bot(the thing on his head). It couldn't take much damage though. Heh, the slightest bump would make a piece come lose. Anyway, we both loved that robot. It was fast and could climb over just about any thing that wasn't a foot tall. This robot was so fun to play with. We had to dismantle it though, once we got an order to build another one. *Sniff* I miss that little guy :(
