Hi, I'm trying to use effort_controllers/GripperActionController controller. In my control.yaml file I wrote:

komodogrippercontroller:

type: effort_controllers/GripperActionController

joints:

• komodo1rightfingerjoint

when I'm running the launch file I getting these error part:

[INFO] [WallTime: 1446978235.329658] [1.490000] Loading controller: komodo_gripper_controller

[ERROR] [1446978235.405154944, 1.560000000]: Could not find joint name on param server

[ERROR] [1446978235.405265648, 1.560000000]: Failed to initialize the controller

[ERROR] [1446978235.405311165, 1.560000000]: Initializing controller 'komodo_gripper_controller' failed

[ERROR] [WallTime: 1446978236.405846] [2.560000] Failed to load komodo_gripper_controller

I can't find the problem. There are any ideas?

Thank!
