  1. Emo Todorov replied to the thread Inverse dynamics through mujoco-py.

    If you have gear ratios different from 1, or control/force limits on your actuators, the results will be different. They will also be...

  2. Emo Todorov replied to the thread Loading a png file as texture.

    I scaled it in Windows Paint, but it doesn't look good because of the stretching. You should crop it instead of scaling it -- just find...

  3. Emo Todorov attached a file to the thread Loading a png file as texture.

    Your image is 600 x 400. You have to edit the PNG so that it is square. Then, you can load it in the model with: <texture...

  6. Emo Todorov replied to the thread nested body and joint type for tensegrity.

    Oh, I was confused. Indeed, you should model each rod as a single body, with a capsule geom and <freejoint/> that makes it a...

  7. Emo Todorov replied to the thread Loading a png file as texture.

    The gridsize defaults to "1 1" but you could set it explicitly to be sure. You can load 6 different files with the attributes fileleft,...

  8. Emo Todorov replied to the thread Modelling 3D Goal for reacher.

    MuJoCo has a special type of body called mocap body. It is fixed for the purposes of physics simulation, but its position and...

  9. Emo Todorov replied to the thread Fake Grasping.

    There is no way to edit the model structure at runtime, because MuJoCo models are compiled. You could however achieve a similar effect...

  10. Emo Todorov replied to the thread Modelling underactuated gripper.

    yes, these are the gear reduction ratios.

  11. Emo Todorov replied to the thread Inverse dynamics through mujoco-py.

    ctrl is a vector of control signals that are sent to the actuators. Do you have actuators in your model, and if so, are they motor that...

  12. Emo Todorov replied to the thread Mujoco VR and roadmap.

    The public version of the VR project is hopelessly behind. There is a new version that works with MuJoCo 1.50 and the Luke Hand model...

  13. Emo Todorov replied to the thread import a mesh as a geom.

    You can map textures on meshes but the texture coordinates are generated automatically, and you have some high-level control over this...

  14. Emo Todorov replied to the thread Loading a png file as texture.

    Cube maps and skyboxes require square images. You can have the same image repeated 6 times, or provide 6 different images. The...

  15. Emo Todorov replied to the thread mj_step for Haptix.

    The HAPTIX API exposes the mj_step function. You can run the MPL model in Pro. It will be faster, because HAPTIX is limited to...
