Why will my URDF model not load into Gazebo?
I have developed a simple robot model using a urdf file and several meshes and I am able to load it up in RViz without issue. However, whenever I try to load it into Gazebo it will not appear. I have tried using several methods such as roslaunch and inserting the model into Gazebo itself.
Here is the urdf file:
