                      QUESTION

                      URDF loading incorrectly in RVIZ but correctly on Gazebo, what is the issue?

                      Asked 2022-Mar-22 at 13:41

                      I have imported a urdf model from Solidworks using SW2URDF plugin. The model loads correctly on Gazebo but looks weird on RVIZ, even while trying to teleoperate the robot, the revolute joint of the manipulator moves instead of the wheels. Is there anyone who has faced this issue before or has a solution to it? Here is how it looks on Gazebo  Model on Gazebo

                      Here is how it looks on RVIZ Model on RVIZ

                      Here is the URDF file of the Model:

                      So, I realized two problems:

                      First, you have to change the fixed frame in the global options of RViz to world or provide a transformation between map and world.

                      Second, your URDF seems broken. There is something wrong with your revolute-typed joints. Changing their type to fixed fixed the problem. I think, it's best if you ask a separate question with a minimal example regarding this second problem.
