Navigation stack - FontysAtWork/ESA-PROJ GitHub Wiki
We used the ROS Navigation Stack as the base of our ROS application. It takes in information from odometry, sensor streams, and a goal pose and outputs safe velocity commands that are sent to the mobile base. This all revolves around the Move base part of the application.
If you need a startingpoint for understanding the workings of the ROS navigation stack we'd recommend looking at the provided tutorials on the ROS Navigation Stack page.
