I am working on a project which involves ROS. The student who worked on the project before me made a program which consists of +20 packages. Unfortunatley he did not document the program well. Now I'm stuck with just folders and files and no idea what he did.
Is there any tool available to visualize the structure and composition of the packages in ROS?
I would like to be able to see what nodes are inside a package, what they publish and subscribe to, and which launch files are connected to which packages and nodes.
