Right now, we can't launch the simulation properly because ROS needs a file (model.urdf) to specify the robot we're trying to simulate. We also need to add a couple of nodes to the launch file, such as a localization node (responsible for figuring out where the robot is) and a pose publisher node (responsible for publishing where the robot is).
