Scorpio is a two-motor, 4-legged walking bot. He is my second analog bot made under the philosophy of BEAM robotics, introduced by Mark Tilden. see http://www3.telus.net/rfws/bwi/index.html for more info about BEAM. Scorpio was supposed to hit a wall and then reverse for about 5 seconds and then (hopefully) head off forward in a slightly different direction. Interestingly enough, due to his unique mechanical configuration, when he hits an obstical, he simply "turns" about 15 degrees and then heads off in another direction. (for those of you that don't know, getting a legged robot to turn can be a challenge!) He is powered by a 9V battery, has two 6 transitor H-Bridges, and to be honest, I built him to get rid of some motors I had in my junk box. Ok, thats probably enough for here... if you want to find out more, including frame and motor information, check out Scorpio's website at: http://www.angelfire.com/electronic/botvideo/scorpio.htm There is even a Video!!! -Sparky Email: sparkyg@seark.net
