    commanding to a joint angle configuration

    Thanks for a quick response. I check mjData.efc_type. It shows a bunch of constraint of type 6 i.e. mjCNSTR_CONTACT_PYRAMIDAL and 1 of type...

    commanding to a joint angle configuration

    I printed everything out for 1 target joint configuration. I got following results ('commanded jt config', array([[-0.65597575, -0.77090292,...

    commanding to a joint angle configuration

    I tried with damping with very small damping value like 2, 0.001 and 0.00001. The oscillates settles to a value which is close to the above posted...

    Making a gym environment

    I think I understand your problem a little bit better now. Have you looked at the body_interaction.py example in mujoco_py-1.50.1 . This is an...

    commanding to a joint angle configuration

    In my current system, I have no gravity. After setting ctrl I ran the simulation for 10k steps. It still doesn't reach to the commanded joint...

    Making a gym environment

    You can look at openai-gym mujoco environments like hopper-v0 etc to get an idea on how to get an image from the simulation. Generally you have...

    inverse kinematics

    I tried out for 2d reacher. The method works and the reacher is able to reach goal position within some error. Here is a video of the simulation....

    inverse kinematics

    The behavior in pydart is that the end-effector reaches the commanded position with the same problem formulation. Here is a video showing...

    inverse kinematics

    I tried to use the mj_jacBody and used the translation jacobian for my model. I implemented the minimization problem in the task space. However...
