Hi everyone:
I used a Revolute Joint and Primastict Joint to simluate a robot arm move and rotate.
It can be work in version 2021.2.1, but in 2022.1.0 version it does not work.
The following video shows the error message, I don’t know how to fixed it. Anyone can
give some advices? Best Regard with you!!

Hi @rthaker ,
I found my issue should be a bug at version 2021.2.1 so that I can make the robot arm do rotate and move in the same time.
After the later version, I found that if you want to make the same object with rotate and move by added joint, it
will be impossibility.
My solution is separate the robot into two parts, one by doing move and the other doing the robot, so now it
can do what I want to do at Isaac Sim version 2022.1.0.
Thanks for your reply . Have a nice day!
