[ROS Q&A] 126 - How to configure the differential drive ROS controller

In this video we are going to see how to configure the differential drive ROS controller for a wheeled robot (two wheels robot) using a Gazebo simulation.

This is a video trying to answer the question of Jaime posted at the ROS answers forum about how he cannot make the ROS controller work for his mobile robot, and receiving the error:

Controller Spawner couldn't find the expected controller_manager ROS interface
