how to use cumotion with multi plan group #349

Hello，I have build up a robot urdf with two arms. I launch moveit setup assistant to define two plan group for each arm. i.e. left_arm and right_arm(each arm have 7 joints). But when I try to use cumotion to plan for left_arm, the cumotion planner node announced that right_shoulder_pitch(one joint of right_arm), is not in the list.

After I read the curobo python file, and print the param, I found that in the follow code new_index_l = [self.joint_names.index(j) for j in joint_names] joint_names have all the 14 joints, while self.joint_names have the left_arm 7 joints. That's why the errror raised.

Now, I want to find out a solution to this problem, any information will be highly appreciated! Thanks a lot!

This feature is currently not supported.

@balakumar-s Thanks for reply. Right now I have another question, I have tried to manager the two arms into one group. And the curobo would work for that. But when I set the joint target for the whole group, I found that the plan result will not reach the certain target I set. I wonder if there is a solution to figure the planner, which will finally make the planner plan to the exact joint target. Thanks!!
