(...) 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)

Here's my opinion: Your CG is too low or your feet are tooo heavy. Your bot is not able able to put enaugh weight over to one side (or the other) to balance on one leg. Try either making lighter feet or raise your CG by raising the motor assembly up (...) (20 years ago, 22-Aug-04, to lugnet.technic)

(...) A useful first step would be to clean up the construction of the motor/gear housing to make it symmetrical. With how jumbled some of those parts look, I'd be very surprised if your center-of-gravity isn't off-center. If it is, that would mean (...) (20 years ago, 22-Aug-04, to lugnet.technic)

A newbie needs some help here... I tried to make a biped COG-shifting walker, based on the many excellent examples found in the archives here. But it doesn't walk -- it just tips up onto the edges of its feet. Here's the starting position (both feet (...) (20 years ago, 22-Aug-04, to lugnet.technic)

(...) Wow, Chris, you have done some really amazing things! I love your home-built air muscle, very clever (and much cheaper than the name-brand kind). I also really like your pneumatic board, with the compressor for recharging the air cylinders. I (...) (20 years ago, 17-Aug-04, to lugnet.technic, FTX)

(...) With Lego pneumatic parts it would be different from the real thing, since Lego cylinders are to coarse in operation, with to much friction to be able to stop accurately at a given position with a given air pressure. However, the way to do it (...) (20 years ago, 17-Aug-04, to lugnet.technic)
