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)

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.

Checks that we have ended inside the goal constraints.

std::vector< int > katana::JointTrajectoryActionController::makeJointsLookup ( const trajectory_msgs::JointTrajectory &  msg) [private]

provides the "query_state" service

Definition at line 363 of file joint_trajectory_action_controller.cpp.

Sets the current trajectory to a simple "hold position" trajectory

bool katana::JointTrajectoryActionController::validJoints ( std::vector< std::string >  new_joint_names) [private]
bool katana::JointTrajectoryActionController::validTrajectory ( const SpecifiedTrajectory &  traj) [private]

Checks if the given KNI trajectory fulfills all constraints.

Parameters:
trajthe KNI trajectory to sample
Returns:
