(...) Yes, there was a lot of work on this at the MIT robotics lab back in the 70s/80s, with bipedal, quadrupedal, and even unipedal hoppers. To get it to work, you need good orientation and/or acceleration sensors (I believe that the MIT folks used (...) (22 years ago, 18-Dec-03, to lugnet.robotics)

Yes, I did a prototype using pneumatics as muscles. It worked semi-well - the thing walked somewhat, although in a very stiff gate. The main problem came from using pneumatics. I couldn't keep the pressure high enough to swing the legs back out (...) (22 years ago, 18-Dec-03, to lugnet.robotics)

Consider the way we walk... we start by effectively starting to lean slightly forward, and we swing a leg some distance in front of ourselves to stop from falling. We then start to bring the other leg forward as we reupright ourselves and repeat the (...) (22 years ago, 18-Dec-03, to lugnet.technic, lugnet.robotics)
