Private Attributes
JointTractoryActionServer	action_server_
	Internal action server.
JointTractoryActionServer::GoalHandle	active_goal_
	Cache of the current active goal.
bool	controller_alive_
	Controller was alive during the last watchdog interval.
trajectory_msgs::JointTrajectory	current_traj_
	Cache of the current active trajectory.
double	goal_threshold_
	The goal joint threshold used for determining if a robot is near it final destination. A single value is used for all joints.
bool	has_active_goal_
	Indicates action has an active goal.
bool	has_moved_once_
	Indicates that the robot has been in a moving state at least once since starting the current active trajectory.
std::vector< std::string >	joint_names_
	The joint names associated with the robot the action is interfacing with. The joint names must be the same as expected by the robot driver.
industrial_msgs::RobotStatusConstPtr	last_robot_status_
	Cache of the last subscribed status message.
control_msgs::FollowJointTrajectoryFeedbackConstPtr	last_trajectory_state_
	Cache of the last subscribed feedback message.
ros::NodeHandle	node_
	Internal ROS node handle.
ros::Publisher	pub_trajectory_command_
	Publishes desired trajectory (typically to the robot driver)
ros::Subscriber	sub_robot_status_
	Subscribes to the robot status (typically published by the robot driver).
ros::Subscriber	sub_trajectory_state_
	Subscribes to trajectory feedback (typically published by the robot driver).
ros::Time	time_to_check_
	Time at which to start checking for completion of current goal, if one is active.
ros::Timer	watchdog_timer_
	Watchdog time used to fail the action request if the robot driver is not responding.
Static Private Attributes
static const double	DEFAULT_GOAL_THRESHOLD_ = 0.01
	The default goal joint threshold see(goal_threshold). Unit are joint specific (i.e. radians or meters).
static const double	WATCHDOG_PERIOD_ = 1.0
	The watchdog period (seconds)
