### robot_mechanism_controllers are not seen?

I've been trying to get a crustcrawler smart-arm to work in ROS. In this last attempt I stripped down the example started with

roslaunch pr2_gazebo pr2_empty_world.launch


But the controllers from robot_mechanism_controllers are NOT seen, in fact there is NO output at all from my launch file after the start of gazebo with my robot.

Please see my (simple) launch file : http://fwn06.housing.rug.nl/ros/testcontrollers.launch, the urdf: http://fwn06.housing.rug.nl/ros/smart_arm_gazebo.urdf, and the controller configuration: http://fwn06.housing.rug.nl/ros/smart_arm_control.yaml

"rosservice call /smart_arm/controller_manager/list_controller_types" lists a fair amount of controllers, but none from robot_mechanism_controllers.

I also tried this configuration: http://fwn06.housing.rug.nl/ros/smart_arm_control-1.yaml, which uses controllers mentioned in the list, but nothing different happens.

Am I missing something? Thanks in advance, Sietse
