Turtlebot4 URDF imoport issue #232
-
|
I saw a tutorial for turtlebot3 and want to try it for the turtlebot4. The .xacro to urdf and the import has no problem at all. After importing to simulation and play it, the turtlebot4 front wheel sank to the ground due to some issue. Does anyone knows what should I fix or configure. |

Thank you for providing details and the screenshot. I noticed you’re using Isaac Sim 4.5.0. There have been significant improvements and bug fixes in subsequent releases, especially related to URDF import stability and physics simulation for mobile robots. If possible, could you try upgrading to the latest Isaac Sim version (5.1.0) and re-importing your Turtlebot4 URDF? This often resolves issues with robot physics, joint configuration, and ground contact that appeared in earlier builds. If the issue persists even in the newest version, please share the updated results. Including all previous troubleshooting details would help further isolate the problem. |

The problem is with the whole chassis and the front wheel is not separated in the original urdf file provided. Sorry for the late reply because I just noticed it :(. |
