ros_control: I cant move my robot in gazebo

[AashithC]

I am using ROS kinetic on Ubuntu 16.04.
I created a 2R URDF model using Solidworks. I added Transmission tags, Gazebo plugin.
A controller.yaml file in config folder and a launch file in launch folder.
while launching
**

roslaunch rr controller_gazebo.launch
I can see controllers using rostopic echo

But the model in gazebo dosent move
why so??

I have installed ros_controller package too
