[Balline] really wanted to play with a hexapod but found the cost to be prohibitive. Being a mechanical engineer, he was able to fairly quickly come up with a stable 3 servo design that would allow him to experiment with the platform. He chose to use wood as the construction material to help reduce costs even more. As you can see in the video after the break, his design gets around fairly well. His cost for the whole thing, including the 3 servos, the basic stamp hobby board, the recycled batteries, and the frame, was under $100.
This is a great system to start with, though he unfairly compares the cost to the dancing ones he had seen in the past. C’mon, your bot ain’t no [Lou Vega]. It is still pretty cool though.
