Do you have a ground plane? Do the legs make contacts with the ground 
plane? Does the contact exert enough force?

You should add a line to the screen for each contact that you're 
creating (easy, because each contact gives you position and normal). You 
might want to scale it by force, if you're using joint feedback mode.

Also, the "mu" field of the contact is a force limiter, unless you use 
the extended contact method (look at the documentation for the flags field).
