  2. Kyokushin liked Emo Todorov's post in the thread 3D Inverse dynamics on experimental data.

    qvel for rotational joint is in radians/sec (and similarly for qacc). The compiled model always uses radians, even if the XML was...

  3. Kyokushin liked Emo Todorov's post in the thread 3D Inverse dynamics on experimental data.

    MuJoCo does not attempt to compute derivatives via finite differences. This is up to the user. It couldn't do that anyway because each...

  4. Kyokushin liked Emo Todorov's post in the thread Control input of actuator/motor (direct drive type).

    For a motor attached to a slide joint, the meaning of ctrl is force (in Newtons, assuming all the other model parameters you entered are...

  5. atabak liked Emo Todorov's post in the thread LQR control of Acrobot.

    The passive simulation is stable, so your controller must be unstable. Maybe you entered the wrong numbers somewhere, or the book you...

  6. atabak liked Emo Todorov's post in the thread LQR control of Acrobot.

    I meant the (implied) units of mass are kilograms. So you are setting the mass to 1000 kg instead of 1 kg. The approximation of pi is...

    Muscle rigged versions of ant / hopper etc?

    Is anyone aware of existing muscle / tendon rigged versions of these models? I'd hate to duplicate work. Thanks in advance!

    That is correct. As mentioned in the first post, I am trying to replicate Spong's LQR controller in MuJoCo. According to his paper, for...

    You have two soft constraints fighting each other: contact vs. equality between the mocap body and object. Which one wins depends on...
