I'd normally open an issue against osrf/gear; but there doesn't seem to be an issues tab on the Bitbucket repository.

I'm having some issues launching the GEAR examples. Namely, when I do roslaunch osrf_gear sample.launch, gazebo opens with the simulation but the arm seems to appear on the ground and only moves very slowly.

Arm on the ground

I also get these error messages when launching:

[ERROR] [1472745023.718771045, 0.001000000]: Could not load controller 'ariac/arm' because controller type 'effort_controllers/JointTrajectoryController' does not exist.

[ERROR] [1472745023.718824000, 0.001000000]: Use 'rosservice call controller_manager/list_controller_types' to get the available types

Error when loading ariac/arm

[ERROR] [1472745023.728961885, 0.009000000]: Could not start controller with name ariac/arm because no controller with this name exists

I thought it may be as simple as me missing effort_controllers but I seem to have them installed already. It seems as if the controller plugin is not existent?

For reference, I wrote this script to do my environment setup so this is what I am using:

Thanks in advance for any help anyone may be able to give.

Turns out I didn't have ros-indigo-joint-trajectory-controller installed. Oopz.

Do a sudo apt-get install ros-indigo-joint-trajectory-controller and have a nice day.
