Written by Ricardo Tellez

Sometimes, your ROS project contains a huge list of launch files that you can barely understand. One launch file launches 3 others, and those launch 4 more, each one with many parameters, arguments and remaps.

In this video, we show you how to quickly understand complex launch files by using RQT (rqt_gui) with a special plugin. We show how to install the plugin and how to use it to analyze the quite strange launch configuration of the Turtlebot simulation.
