Detailed Description

template<class Distance>
class frc2::TrapezoidProfileSubsystem< Distance >

A subsystem that generates and runs trapezoidal motion profiles automatically.

The user specifies how to use the current state of the motion profile by overriding the UseState method.

This class is provided by the NewCommands VendorDep

Constructor & Destructor Documentation

◆ TrapezoidProfileSubsystem()

template<class Distance >

frc2::TrapezoidProfileSubsystem< Distance >::TrapezoidProfileSubsystem	(	Constraints	constraints,
		Distance_t	initialPosition = `Distance_t{0}`,
		units::second_t	period = `20_ms`
	)

inlineexplicit

Creates a new TrapezoidProfileSubsystem.

Parameters

constraints	The constraints (maximum velocity and acceleration) for the profiles.
initialPosition	The initial position of the controller mechanism when the subsystem is constructed.
period	The period of the main robot loop, in seconds.

Member Function Documentation

◆ Disable()

template<class Distance >

void frc2::TrapezoidProfileSubsystem< Distance >::Disable ( )

inlineprotected

Disable the TrapezoidProfileSubsystem's output.

◆ Enable()

template<class Distance >

void frc2::TrapezoidProfileSubsystem< Distance >::Enable ( )

inlineprotected

Enable the TrapezoidProfileSubsystem's output.

◆ Periodic()

template<class Distance >

void frc2::TrapezoidProfileSubsystem< Distance >::Periodic ( )

inlineoverridevirtual

This method is called periodically by the CommandScheduler.

Useful for updating subsystem-specific state that you don't want to offload to a Command. Teams should try to be consistent within their own codebases about which responsibilities will be handled by Commands, and which will be handled here.

Reimplemented from frc2::Subsystem.

◆ SetGoal() [1/2]

template<class Distance >

void frc2::TrapezoidProfileSubsystem< Distance >::SetGoal ( Distance_t goal )

inline

Sets the goal state for the subsystem.

Goal velocity assumed to be zero.

Parameters

goal	The goal position for the subsystem's motion profile.

◆ SetGoal() [2/2]

template<class Distance >

void frc2::TrapezoidProfileSubsystem< Distance >::SetGoal ( State goal )

inline

Sets the goal state for the subsystem.

Parameters

goal	The goal state for the subsystem's motion profile.

◆ UseState()

template<class Distance >

virtual void frc2::TrapezoidProfileSubsystem< Distance >::UseState ( State state )

protectedpure virtual

Users should override this to consume the current state of the motion profile.

Parameters

state The current state of the motion profile.
