| | | Hey, why are you making quadrupeds that can't actually walk. That's too easy! It's time you made a motorized four legged walker. Quadrupeds are inherently stable and don't require dynamic control other than gearing, but with an RCX it could do (...) (21 years ago, 24-Mar-04, to lugnet.build.mecha, FTX)

| | | | (...) ahhhhem. Quadrapeds are only inherently stable if the feet are big enough. If you break the four legs into two leg groups, worst case scenario is two feet on the ground. You'd better makes sure the center of gravity is within the diagonal (...) (21 years ago, 24-Mar-04, to lugnet.build.mecha, FTX)

In a mathematical world of pinpoint feet, the two feet on the ground might not be stable, but a Lego four legged walker probably wouldn't keel over while following a gait matrix. In the worst (...)

Could you please educate me about "gait matrix"? I've not heard of (...) (21 years ago, 25-Mar-04, to lugnet.build.mecha, FTX)

It gives the legs their coherent propulsive movement. Any autonomous walker needs to have (...) (21 years ago, 25-Mar-04, to lugnet.build.mecha, FTX)
