Isaac Sim ROS 2 Bridge
Purpose
Publish and subscribe to ROS 2 topics from Isaac Sim using OmniGraph bridge nodes, including Nav2 integration and multi-robot namespacing.
Limitations
- Targets Isaac Sim 6 / Kit 110 unless a section states otherwise.
- Does not replace official NVIDIA documentation for unsupported edge cases.
Troubleshooting
| Error / symptom | Cause | Solution |
|---|---|---|
| No ROS topics | Bridge graph not playing or wrong domain | Press Play; set ROS_DOMAIN_ID consistently |
| Missing humble libs | LD_LIBRARY_PATH not set before process start |
Fix the parent shell (source ROS env or use default launcher), then relaunch — do not hot-patch a running process |
| Namespaced topic mismatch | Frame or namespace drift | Align OmniGraph namespace with Nav2 config |
