This is my first head bot.  I used Junkbots, Bugbots, and Bots on Wheels as a guide to its completion.  For the bicore configuration I used a Solarbotics BC2 PCB.  The stand is made from ten gauge copper wire and soldered to a Solarbotics LMP1 PCB (Very handy for mounting legs to servos).  It runs off of four Ni-Cd AA batteries, making it extremely active.
