BEAM is field of robotics pioneered by Mark Tilden. BEAM robots often use deceptively simple designs with a minimalist aesthetic can often result in complex analog behavior. Keep an eye open for a post about Huey, one of Mark’s latest robots, later today.

You can try your own hand at building a very simple BEAM robot pet with this Solar Trimet Project.

A Trimet is a simple BEAM spinner with three symmetrically-balanced components. It incorporates a common BEAM solar power management circuit called a voltage-triggered solar engine. It is basically comprised of the solar engine, a DC motor scavenged from a cassette player, a solar cell, and three capacitors that store the energy from the cell (and also act as the main structure of the “bot”).
