gazebo simulation of robotiq gripper, can't control it

[ancorasir]

trying to follow the tutorial and control the grizzly, but it seems there's no controller connected to the gripper, the joints in the gripper are much more than those in the robotiq_gripper_controller.yaml file.

Any suggestions? Not sure which part went wrong but kept getting the following message.

[WARN] [WallTime: 1484834699.637533] [20.158000] Controller Spawner couldn't find the expected controller_manager ROS interface.

Just a note that I'm running Indigo and the package is in Hydro. Would this be the critical problem here? Thanks in advance.
