Nested articulation roots are not allowed

“Please check Figure 3 and the attached file. I used o3dyn based on WSL in Isaac Sim 2023-1.1. However, after upgrading to Isaac Sim 4.1, it no longer works. The error message I received is: 2024-08-01 12:15:02 [Error] [omni.physicsschema.plugin] UsdPhysics: Nested articulation roots are not allowed. How should I modify the articulation_controller to resolve this?”

“I’m a beginner with Isaac Sim. Thank you for the help.”

“I couldn’t upload the file, so I’ve attached a link instead. I used the o3dyn_ros2 version and did not use the RTX version.”

Have you made any modifications? I’m in the same situation

yes
Nice to meet you kqu0585

It was an easy problem.
There was a difference between isaac sim 2023 and 4.1. It can be resolved by correcting the error.
