3D modeling software such as SketchUp or Blender can be used to generate mesh designs for the 3D model, which can be exported in either *.dae or *.sdf format. We can create a URDF file and view the model on RViz. However, the detailed process for developing the mesh design for a 3D model using modeling software is beyond the scope of this book, but an advanced reader can find the resources on the web.

Nevertheless, we have the file named bot.dae in the robot_description/meshes folder at GitHub, which is a basic mesh design of the mobile robot model for demonstration purposes.

Hence, we will learn how to use the mesh design of a 3D model using the URDF file. Therefore, we will create a new file in the robot_description/urdf
