If you have motors controlling the legs, you can set the dParamFMax =
parameter to a low value, meaning that you can push against the motor =
easily. I think a similar thing happens with other hinges, I'm not sure =
tho :)

Subject: [ODE] passive legs
hi folks.
i am working on a six legged robot. now i have the prob that with all =
legs on the ground and one leg moving (stancing the body) i do not get =
the desired effect as of course the other legs hold tight. to fix that =
problem (any smarter thoughts on this?) i thought about making the =
hinges that move my legst front and back passive unless they are unter =
control (means swinging or stancing). so how can i do this ?
would setting fMax of the the hinges to 0 let the hinges be moved =
freely ?
maybe someone could comment/help me on this...
thanx...
cya&bfn, mike
