We explain how to write the xacro, gazebo, and Python launch files that model and simulate the model. Also, we explain how to control the robot by using the keyboard keys. In our previous tutorial, we explained how to do the same modeling task in ROS1. However, it is far from trivial to generalize the ROS1 implementation to the ROS2 implementation. Namely, to model the robot in ROS2, we had to write a completely new launch file, and significantly modify the Xacro model files, such that the model could be properly displayed and simulated in Gazebo. Furthermore, the process of building the workspace and packages in ROS2 is completely different from ROS1.
