BEAM Solar Symets (a contraction from "Symmetrical Robots") were first built by Mark Tilden many years ago as a way to provide mobile plant-life to the other creatures in his Robot Jurassic Park. Being quite simple by only using one solar-engine circuit, they're quick and easy to build.

These versions use high-power Miller Solar Engine circuits, that make them spin much more madly than their pokey ancestors! If you are new to BEAM, it's a design philosophy that incorporates minimalist electronics, and often, solar power. Want more info? Check out Solarbotics.com and Solarbotics.net!

The Battle Symet borrows heavily from the original family of Symets, but these are designed to spin in a circle at much higher speeds.

We've made a convenient parts bundle of almost everything you'll need to build this project (not including the tools). You'll have all the mechanical and electrical components needed to start making this fun lil' robot!
