Member Function Documentation

bool katana::JointTrajectoryActionController::allJointsStopped ( ) [private]

Checks that all joint velocities are zero.

Definition at line 610 of file joint_trajectory_action_controller.cpp.

boost::shared_ptr< SpecifiedTrajectory > katana::JointTrajectoryActionController::calculateTrajectory ( const trajectory_msgs::JointTrajectory & msg ) [private]

Definition at line 207 of file joint_trajectory_action_controller.cpp.

void katana::JointTrajectoryActionController::commandCB ( const trajectory_msgs::JointTrajectory::ConstPtr & msg ) [private]

Callback for the "command" topic. There are two ways of sending a trajectory: 1. by publishing a message to the "command" topic (this is what happens here) 2. by using the action server (see executeCB)

Definition at line 191 of file joint_trajectory_action_controller.cpp.

void katana::JointTrajectoryActionController::executeCB ( const JTAS::GoalConstPtr & goal ) [private]

Definition at line 422 of file joint_trajectory_action_controller.cpp.

void katana::JointTrajectoryActionController::executeCBFollow ( const FJTAS::GoalConstPtr & goal ) [private]

int katana::JointTrajectoryActionController::executeCommon	(	const trajectory_msgs::JointTrajectory &	trajectory,
		boost::function< bool()>	isPreemptRequested
	)		`[private]`

Returns:: either one of control_msgs::FollowJointTrajectoryResult, or PREEMPT_REQUESTED

Definition at line 471 of file joint_trajectory_action_controller.cpp.

bool katana::JointTrajectoryActionController::goalReached ( ) [private]

Checks that we have ended inside the goal constraints.
