Hi,

I'm trying to use the /gazebo/set_model_configuration service to set a
starting pause for my arm (as suggested here:
http://answers.ros.org/question/857/set-revolute-joint-start-angle).

I'm getting the following error:
 gazebo_model canonical body[world] is not the root link[shadowarm_base]!

When I spawn my model, I'm specifying world as the reference_frame though.
(rosrun gazebo spawn_model -urdf -param robot_description -model
arm_and_hand -reference_frame world)

Any help greatly appreciated.

Cheers,

Ugo
