Launching my_robot_configuration launch file
Hello!
I am going through the navigation stack tutorials and I've hit somewhat of a conceptual roadblock. For the my_robot_configuration.launch tutorial section, it states to create a launch file that will launch 3 nodes for the necessary topics for navigation (Odometry, tf, sensor).
However I have been slowly building up a simulation of a rover that is already publishing to these topics ( I have a gazebo plugin skid_steer that is already publishing odometry and hokuyo laser plugin that's already publishing sensor data)
I'm struggling to understand if its necessary for me to make new nodes to publish the same information. Or if it serves extra purpose.
My ultimate goal is to implement a ROS based rover first in simulation and then in real life, if anyone has already done this and is willing to talk with me about it, I would love to talk!!
Thank you!
