  1. Emo Todorov replied to the thread Parameter for quat attribute XML.

    MuJoCo allows you to specify frame orientations in several different ways. Using quaternions is a low-level feature. See here:...

  2. Emo Todorov replied to the thread Parameter for quat attribute XML.

    the order is q = (w,x,y,z) if you want to rotate by angle theta (in radians) around axis v where v is a unit vector, set: w =...

  3. Emo Todorov replied to the thread Constraint violations in fixed length tendons?.

    If it looks over-damped already then it may not be the answer... if you send me your model I can take a look.

  5. Emo Todorov replied to the thread Strange dynamics with composite object.

    This should not be happening. It may help to turn on the visualization of contact points and contact forces and see what contacts are...

  6. Emo Todorov replied to the thread Constraint violations in fixed length tendons?.

    It sounds like you need some damping in the system. Try adding damping to the joints. You could also add damping to the equality...

  7. Emo Todorov replied to the thread limited freejoint.

    No, but in this case you should be using a hinge joint anyway.

  9. Emo Todorov replied to the thread Computational burden of inactive joint limits.

    It barely has any influence. All constraints are checked at each time step, but the check is very simple, and if they are inactive no...
