BEAM is an acronym for Biology Electronics Aesthetics and Mechanics.
These robots are ingeniously simple and instead of having complex <a a="" brain")="" class="wiki" for="" href="/wiki/microcontroller.html" robot"="" title="A programmable digital controller (or ">Microcontrollers</a> and programs, you can use wave generators which are very close to having their stability pulled out by sensors.
Some of these are also simple circuits with a capacitor, which after reaching a trigger voltage, causes a Transistor to flip. This will drive a motor for a breif burst of motion, then stop after the capacitor is fully discharged. A great use of Solar Panels and pretty easy to build.
Legged robots can be built in interesting ways using sine(or relatively curved waveforms) offset by 90/180 degrees. If used with Muscle Wire - it means you can get a set of flowing contractions just from the wave generators.
Some people like the idea of taking the BEAM principles, and creating a Horse And Rider Robot - a very interesting proposition indeed.

|Junkbots, Bugbots and Bots on Wheels: Building Simple Robots with BEAM Technology||Dave Hrynkiw, Mark W. Tilden||This book is an excellent starters guide, and anybody intending to build these robots should have it on their shelf. I have built many robots based upon these ideas. It covers tools, techniques, actual robot designs and more.|
