[ROS Q&A] 112 - How to manually tune a PID with ROS Control

We show you a manual method to tune a PID for a robot that uses ROS Control to control its joints with a position controller. This method is very artisanal but it is enough for most of the cases.

The method presented comes from a description of it at the official Gazebo tutorials about ROS Control. You can read the text here: http://gazebosim.org/tutorials/?tut=ros_control

We do not teach how ROS Control works in this video. We assume you already know how to configure a joint to work with the ROS controllers. If you need to understand better ROS Control, please take the following course for fast understanding:
