how to use diff_drive_controller
I have installed ros_control, ros_controllers, and diff_drive_controller under ROS indigo. however, I am having issues getting the diff_drive_controller node to rosrun.
normally i can tab complete the node executable (e.g rosrun joy joy_node). however, diff drive does not allow autocomplete, and doesn't seem to have an executable. perhaps I have missed something that needs to be set up, but i've read the wiki page a few times and haven't found anything outstanding that would seem to break the install.
