Before creating the URDF file for the robot, let's create a ROS package in the catkin workspace so that the robot model keeps using the following command:
$ catkin_create_pkg mastering_ros_robot_description_pkg roscpp tf geometry_msgs urdf rviz xacro
The package mainly depends on the urdf and xacro packages, and we can create the urdf file of the robot inside this package and create launch files to display the created urdf in RViz. The full package is available on the following Git repository, you can clone the repository for a reference to implement this package or you can get the package from the book's source code:
$ git clone https://github.com/qboticslabs/mastering_ros_robot_description_pkg.git
Before creating the urdf file for this robot, let's create three folders called urdf, meshes, and launch inside the package folder. The urdf folder can be used to keep the urdf/xacro files that we are going to create. The meshes folder keeps...
