Chapter 3. Visualization and Debugging Tools
ROS has a good number of tools which allow the user and the developer to visualize and debug their code in order to detect and solve issues with both hardware and software. This comprises a message logging system similar to log4cxx, diagnostic messages, and also visualization and inspection tools, which provide a comprehensive list of the running nodes as well as how are they interconnected.
