Joint Trajectory Action server doesn't publish JointTrajectoryControllerState message #76
Description
PR2 have topics to get joint trajectory controller state such as /l_arm_controller/state... The message type is pr2_controllers_msgs/JointTrajectoryControllerState.
joint_trajectory_controller in ros_controllers package also publishes joint trajectory controller state as <controller_name>/state The message type is control_msgs/JointTrajectoryControllerState.
These two messages are the same.
But on Baxter, /baxter_joint_trajectory doesn't publish joint trajectory controller state, I think.
/robot/limb/right/state and /robot/limb/left/state exist, but these topics are totally different from topics above.
$ rostopic info /robot/limb/right/state
Type: baxter_core_msgs/AssemblyState
We should add JointTrajectoryControllerState message topic, shouldn't we?
