is the second of its kind.
     For just a little over a year now I've indulged in this new-found hobby, taking apart useless electronics and building little bug-bots. It was several years ago that I first learned about Mark W. Tilden and his approach to the robot world.
     Eight years ago I sat in awe as I watched on the TV screen this little robotic bug-like walker climbing all over the desk and over key-boards. It was a special on robots and they where interviewing Mark Tilden. He said that anyone could make these out of simple parts from a walkman.
I could not believe my eyes, this guy is telling me I can make these killer looking/moving robots from all that junk in my garage. And sure enough, here I am today doing just that.
     Thanks to the internet and this age of information I was able to dive into the world of BEAM. BEAM is an acronym meaning...

Biology Electronics Aesthetics Mechanics
Building Evolution Anarchy Modularity
Biotechnology Ethnology Analogy Morphology

You can find out lots about it at my favorite site solarbotics.

This is actually the very first walker I made. I took most of the design from the book "Junkbots, Bugbots, & Bots on Wheels" (written by Dave Hrynkiw & Mark W. Tilden). One of the last projects is making a walker. I pulled the steering servos out of two Zip-Zap cars, a battery from a Zip-Zap truck, and the rest was history.

     There is a difference here between BEAM bots and the digital-type like the BOE programable robot. BEAM bots are designed to use the environment as its variables rather than a program. This is how very simple circuitry can create a very life-like creature. All of its movements are based on lighting, ground surface, objects, and the like. BEAM bots even respond to the interaction of pets and people.
     BEAM technology does use programming in the more sophisticated robots. It is to control other aspects of the robot like what to do when a command is given and ignore how to physically do it. The BEAM technology almost proves you can have a bot without a brain, but not a brain without a bot... Ha ha ha, oh, sorry about that.
