We intend to install on Foxy (the latest LTS ROS release), which drives the version requirements for the rest of the installation: Ubuntu 20.04 Focal, Gazebo 11, and the ROS 2 installation of TurtleBot3. Lets create now the launch file to easily launch the simulation and the ROS controller with a single command. It first gets the robot instance from the simulation (which can be used to access the Webots robot API). Result: In your case, you need to run a single instance of this node, because you have a single robot in the simulation. This is actually a fairly simple text file you can visualize in a text editor. Introduce the ROS2 bridge and ROS2 OmniGraph (OG) nodes.
