[ROS Q&A] 129 - Which ROS controllers required for PR2 ?

In this video we are going to see why a ROS developer can't launch a PR2 Gazebo simulation, mainly because the ROS controllers are not found.

We will see which are the ROS packages which provide all the required controllers for the PR2. We will also see how you can apply this check to your own robot simulation, in case it complains about the controllers not being loaded.

This is a video trying to answer the following question posted at the ROS answers forum: https://answers.ros.org/question/294245/roslaunch-pr2_gazebo-pr2_empty_worldlaunch/
