Hello,
I think I understand what the problem is. Formerly in the rosbot_ros package, it contained the absolute path to the mesh file. What was fixed some time ago.
To fix this, it is necessary to build the package in the ros2_ws folder or faster copy all meshes from rosbot_ros to: ~/ros2_ws/install/rosbot_description/share/rosbot_description/meshes/wheel_a.dae directory.
It is run with docker compose -f compose.new.yaml up command. Remember to disable previously running robot and sensor containers if docker compose down is enabled.
Let me know if you managed to solve the problem
