Although not a true BEAM robot, this simple schematic by Randy Sargent is small, simple, slick, and effective. My own version uses a pair of pager motors and three cells from a 9V rechargeable battery. Hard to get any simpler than this device!

Sumobot Circuits
We've been having fun playing with the L293D driver chip. It's one of those things to see how much you can make it do by itself (like with any BEAM application!).
