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!

The night before WCRG, and all through the office, not a creature was stirring...except two dozen mini-sumo robots - AAAHH! Thanks to Alberta Printed Circuits, we were able to sponsor a mini-sumo workshop to build 24 robots to compete in the next day's Western Canadian Robot Games.
Inspired by the Ice Bulb published on Instructables, we decided to create our own version. Ice bulb suggests that we use a balloon to shape the ice and before it freezes, add an LED so that it can glow. Since we decided to use a whole bunch of LEDs (on a string), we opted to […]
Got a new kit for you - the K SMD L293D Motor Driver. No, no, the SMD isn't "surface mount" - it's the Secret Motor Driver! This L293D-based motor driver fits secretly inside most standard servo cases like the Futaba S3003/S148, and our own GM4 gear motors. It replaces the low-voltage original electronics with LED-indicated, […]
