Topic Description

Configuration for Joint Position Controller cannot be saved

Detailed Description

I am still learning about isaacsim. I created a franka arm and created a Tools/Robotics/OmniGraph Controller/Joint Position for the franka arm. Everything works when I start simulation. When I save it and reopen it, the controller no longer works. I started the simulation, drag the JointCommandArray position in properties, and nothing moves.

Steps to Reproduce

1. Create a Franka Arm

2. Create Joint Position Controller for Franka Arm

3. Save and reopen the USD.

4. Control the Franka Arm with Joint Position Controller

Additional Information

What I’ve Tried
