where is the node for follow_joint_trajectory action server (control_msgs/FollowJointTrajectory)
I just noticed that move_arm is looking for arm_controller/follow_joint_trajectory with action type: control_msgs/FollowJointTrajectory.
Earlier I was running arm_controller/joint_trajectory_action with action type: pr2_controllers_msgs/JointTrajectoryAction which make an interface between arm_controller and move_arm. which is documented here.
Now I need to run action node of type control_msgs/FollowJointTrajectory so that it can interface with move_arm.
Can I get the information about where is the ros node for implementing action server for controllers of the type control_msgs/FollowJointTrajectory?? OR it is a part of something else.
