This section features some of my solar powered BEAM robots based on hardwired behavior and novel mechanical designs.

If you want to make robots like these, you can! I recommend you buy one or both of these books:

JunkBots, Bugbots, and Bots on Wheels: Building Simple Robots With BEAM Technology

and / or

Make, Volume 6: Technology on Your Time (Make: Technology on Your Time)
