Detailed Description

A 'Half' Trapezoidal VelocityProfile. A contructor flag indicates if the calculated profile should be starting or ending.

Definition at line 63 of file velocityprofile_traphalf.hpp.

Constructor & Destructor Documentation

KDL::VelocityProfile_TrapHalf::VelocityProfile_TrapHalf	(	double	_maxvel = `0`,
		double	_maxacc = `0`,
		bool	_starting = `true`
	)

Parameters:

maxvel	maximal velocity of the motion profile (positive)
maxacc	maximal acceleration of the motion profile (positive)
starting	this value is true when initial velocity is zero and ending velocity is maxvel, is false for the reverse

void KDL::VelocityProfile_TrapHalf::SetProfileDuration	(	double	pos1,
		double	pos2,
		double	newduration
	)		`[virtual]`

Can be used to prolong the profile, there are two possible outcomes: in a first phase the acceleration is lowered as such that the end position and maximum velocity are reached at the given duration (newduration). In this case there is an acceleration part and a constant velocity part, when this reaches a minimum acceleration value at which the constant part disappears, the motion is stalled, in this case their is a non-motion part and an acceleration part.

Parameters:

pos1	starting position
pos2	ending position
newduration	the desired duration, if it is lower than the minimum duration, the minimum duration will be used instead of the given duration.
