Hello,

I'm busy with a custom made robotic arm with dynamixels. I tried to make the Clam arm package work: http://correll.cs.colorado.edu/clam/?page_id=277 But I get this error:

[ERROR] [1432652016.571410483]: Action client not connected: clam_trajectory_controller/follow_joint_trajectory
[ERROR] [1432652016.583555964]: No controller handle for controller 'clam_trajectory_controller'. Aborting.

I can't find the error myself. Anybody who succeeded with the clam arm? And maybe have some recomendations?
