| (...) I think I've seen four-legged walkers that turn the same way that a tank tread vehicle turns -- walk the two legs on one side forward and the other side backwards. Not the most efficient way to do this, but possibly the easiest to construct. (...) (25 years ago, 1-Nov-99, to lugnet.robotics)

| (...) There are probably many ways for a walker to turn. A simple one is the "triple gait cycle hexapod", which can walk both forwards and backwards, in addition to turning either way. I have made a triple gait cycle hexapod based on the Cybermaster (...) (25 years ago, 1-Nov-99, to lugnet.robotics)
