Constructor & Destructor Documentation

DUNE::Maneuvers::FollowTrajectory::FollowTrajectory	(	const std::string &	name,
		Tasks::Context &	ctx
	)

Constructor.

Parameters

name	name.
ctx	context.

DUNE::Maneuvers::FollowTrajectory::~FollowTrajectory ( void  )

virtual

Destructor.

Member Function Documentation

virtual bool DUNE::Maneuvers::FollowTrajectory::canInit ( const IMC::FollowTrajectory *  msg )

pure virtual

Method invoked on maneuver startup.

By default the base class implementation does nothing.

Parameters

msg	maneuver message

Returns

true if we can proceed with the maneuver, false otherwise

void DUNE::Maneuvers::FollowTrajectory::consume

(

const IMC::FollowTrajectory *

msg

)

Consumer for IMC::FollowTrajectory message.

Parameters

msg	maneuver message

References DUNE::IMC::CL_PATH, DUNE::IMC::FollowTrajectory::lat, DUNE::IMC::FollowTrajectory::lon, DUNE::IMC::FollowTrajectory::speed, DUNE::IMC::FollowTrajectory::speed_units, DUNE::IMC::FollowTrajectory::z, and DUNE::IMC::FollowTrajectory::z_units.

void DUNE::Maneuvers::FollowTrajectory::consume

(

const IMC::EstimatedState *

msg

)

Consumer for IMC::EstimatedState message.

Parameters

msg

message

References DUNE::IMC::Message::getTimeStamp().

void DUNE::Maneuvers::FollowTrajectory::consume

(

const IMC::PathControlState *

msg

)

Consumer for IMC::PathControlState message.

Parameters

msg	path control state message

References DUNE::IMC::PathControlState::FL_NEAR, and DUNE::IMC::PathControlState::flags.

double DUNE::Maneuvers::FollowTrajectory::controlPeriod ( void  ) const

inline

Get control step period.

Returns

control step period.

void DUNE::Maneuvers::FollowTrajectory::desiredPath	(	const TPoint &	start,
		const TPoint &	end
	)

Set the desired path.

References DUNE::Coordinates::WGS84::displace(), DUNE::IMC::DesiredPath::FL_START, DUNE::Maneuvers::FollowTrajectory::TPoint::x, DUNE::Maneuvers::FollowTrajectory::TPoint::y, DUNE::Maneuvers::FollowTrajectory::TPoint::z, and DUNE::Maneuvers::FollowTrajectory::TPoint::z_units.

void DUNE::Maneuvers::FollowTrajectory::desiredSpeed	(	double	value,
		uint8_t	units
	)

Set the desired speed.

References DUNE::IMC::FollowTrajectory::speed, DUNE::IMC::DesiredSpeed::speed_units, and DUNE::IMC::DesiredSpeed::value.

bool DUNE::Maneuvers::FollowTrajectory::isApproaching ( void  ) const

inline

Check if maneuver is still in approach stage (i.e.

moving to the initial point).

Returns

control step period.

void DUNE::Maneuvers::FollowTrajectory::onManeuverDeactivation

(

void

)

Method called upon maneuver deactivation.

virtual void DUNE::Maneuvers::FollowTrajectory::onPathCompletion ( void  )

pure virtual

Abstract method called upon path completion.

This will not be called in approach stage (see isApproaching()).

virtual void DUNE::Maneuvers::FollowTrajectory::onReset ( void  )

inlinevirtual

Method invoked on maneuver reset.

By default the base class implementation does nothing.

void DUNE::Maneuvers::FollowTrajectory::onUpdateParameters ( void  )

virtual

const TPoint& DUNE::Maneuvers::FollowTrajectory::point ( int  t_index ) const

inline

Get a point in the trajectory.

Parameters

t_index

index of point

Returns

corresponding traj. point

virtual void DUNE::Maneuvers::FollowTrajectory::step ( const IMC::EstimatedState &  state )

pure virtual

Abstract method invoked for trajectory control.

This will be invoked periodically according to the control step period (see controlPeriod()) after the initial approach stage has concluded (see isApproaching()).

size_t DUNE::Maneuvers::FollowTrajectory::trajectory_points ( void  ) const

inline

Get number of points in the trajetory.
