How to fix some joints and only allow other joints to move

Discussion in 'Modeling' started by Adarsh Sehgal, Apr 11, 2018.

  1. Hi,

    I have a model of aubo i5 robot as attached. I am trying to fix the position of some joints and direction of movement of other joints. Basically, instead of robotic arm to move in 360 degrees. I am trying to move in kinda 2D planar axis. Is there a way I can restrict its movement to match my requirement?

    Not quite sure what you mean (and I cannot load your model because STL files are missing), but in general you can restrict the motion in two ways:

    -- create joints only as needed, and set their axes appropriately (as well as joint ranges). If there is no joint, there is no motion.
    -- if joints are not enough, use equality constraints.
