Andy, I think the curved foot concept is the wrong direction for a two-legged mechanism. The few simple two-legged mechanisms I have seen rely on two feet, each with a VERY large footprint. Each footprint is large enough to support the weight of the (...) (24 years ago, 23-Mar-01, to lugnet.robotics)
