| | | (...) Good explanations so far. Here are some additions. The problem is that you are not truly getting the center of gravity inside the footprint of the down foot. The critical part is to get the center of gravity past the inside edge of each foot. (...) (20 years ago, 22-Aug-04, to lugnet.technic)

At the start of a walk cycle (when we go from both feet flat to one foot lifting), you have one foot lifting (...) (20 years ago, 22-Aug-04, to lugnet.technic)

It now walks quite reliably! Very cool. This bot is cute in a sort of (...) (20 years ago, 23-Aug-04, to lugnet.technic)
