Animating a robot in dops

Hi,
I'm trying to simulate a robot in dops. The goal is to use external inputs to drive the joints and have it walk. But for now I haven't found a working setup. This is my first real project with dops so I might have missed something obvious.

My first attempt was to just animate the limbs in sops and bring the whole robot into dops as deforming geometry. Unfortunately friction only seems to work for the object as a whole and not for individual parts like the feet. So the robot just slides on the spot and can't move forward.

The next thing I tried was to link all the body-parts with constraints in dops and use angular constraints with animated goal rotations. This works but is very very unstable even for basic setups.

Does anyone have a solution to the instability or another approach for this kind of simulation?


thank you
