Not able to set limit for Slide type joint

Discussion in 'Support requests' started by Deepak, Aug 2, 2019.

  1. I am using a slide type joint in my robot for connecting the main body with a part. This part should contract when it collides with some object. I am able to achieve the same using a slide type joint. But the joint is expended(before the collision) more than what I set in the limits. How I can effectively set the joint limit/range?

    <joint name="joint_x" type="slide" axis="1 0 0" pos=".05 .05 .05" limited="true" range=".01 .02"/>

    Joint limits are soft, like all other constraint in mujoco. You can adjust the softness of each constraint with the corresponding solref and solimp parameters.
     
  3. solimplimit worked for me. Thanks for the suggestion.
     
  4. What did you set solimp limit to?
     
  5. For my case solreflimit="0.09 0.10" solimplimit="0.90 1.00 0.000001" worked.
