Our latest Weekend Project will have you exploring the field of BEAM robotics, which… wait, did that Symet just move on its own accord? Yes, these BEAM Solar Chariots have a mind of their own! Well not really a mind, more like a nervous system that stores up solar power and then discharges it, producing movement. Inspired by nature, BEAM stands for Biology, Electronics, Aesthetics, and Mechanics, which both informs and inspires BEAM design and function. The Solar Roller and Symet both use the same circuit design, dubbed “solar engine,” named so for deriving its energy from solar light. With various technoscrap parts — we salvaged ours from an old micro-cassette player – and common components (transistors, resistors, LED, and capacitors) hooked up to a solar cell, you can build one of these little critters!

The Solar Roller move forward with bursts of energy, while the Symet spins around on its DC motor’s axle. Watch the video below to see both these vehicle being built and in action, then head over to the project page to start making your own BEAM critters!
