Moveit: generating a motion plan fixing the state of a joint

asked 2020-06-12 14:10:02 -0600

I would need to keep one joint fixed in a moveit arm motion plan. I know that is possible creating different moveGroups that excludes some joints but the idea in this case is using the actiive movegroup that also contains the target fixed joint.

I tried to do that using JointContraints but it did not work, something like this:

    jc.joint_name = "torso_lift_joint";  
    jc.position = getCurrentTorsoValue;
    jc.tolerance_above = 0.05;
    jc.tolerance_below = 0.05;
    jc.weight = 1.0; 



How could I generate a moveit arm motion plan with some joints keeping a fixed value?
