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)

Perhaps you should let John Barnes answer for himself. Different people have different approaches here. Dave Baum, for example, has spent huge amounts of effort on NQC and has been quite happy for people to use his invention. (...)
