I am trying to control a dynamixel ax-12 servo by using kinect.. I just use one servo
I followed the tutorials in pi_robot package http://www.ros.org/wiki/openni/Contests/ROS%203D/Skeleton%20Tracker%20Teleoperation%20Package%20for%20Mobile%20Robot
When I start robotis.launch, it works fine..
But when i start dynamixels.launch to control my servo.. it has problems..

I'm not sure why the controller_manager None to start up..
dynamixel.launch ( for a while, I just one servo )
