I've got the same problem and I've figured it out how to solve it. You are having this problem cause you don't have installed the controllers. Just run these commands in your terminal:

sudo apt-get update

sudo apt-get install ros-indigo-ros-control ros-indigo-ros-controllers`

After that when you try to run the same commands you'll be able to control the arm of rrbot.
