Detailed Description

A circular Path with 'open ends'. Path_Arc would have been a better name though.

Member Function Documentation

Twist KDL::Path_Circle::Acc	(	double	s,
		double	sd,
		double	sdd
	)		const `[virtual]`

Returns the acceleration twist at path length s and with derivative of s == sd, and 2nd derivative of s == sdd

Implements KDL::Path.

Definition at line 120 of file path_circle.cpp.

Path * KDL::Path_Circle::Clone ( ) [virtual]

Virtual constructor, constructing by copying, Returns a deep copy of this Path Object

Implements KDL::Path.

Definition at line 135 of file path_circle.cpp.

virtual IdentifierType KDL::Path_Circle::getIdentifier ( ) const [inline, virtual]

gets an identifier indicating the type of this Path object

Implements KDL::Path.

Definition at line 107 of file path_circle.hpp.

double KDL::Path_Circle::LengthToS ( double length ) [virtual]

LengthToS() converts a physical length along the trajectory to the parameter s used in Pos, Vel and Acc. This is used because in cases with large rotations the parameter s does NOT correspond to the lineair length along the trajectory. User should be sure that the lineair distance travelled by this path object is NOT zero, when using this method ! (e.g. the case of only rotational change) throws Error_MotionPlanning_Not_Applicable if used on composed path objects.

Implements KDL::Path.

Definition at line 95 of file path_circle.cpp.

double KDL::Path_Circle::PathLength ( ) [virtual]

Returns the total path length of the trajectory (has dimension LENGTH) This is not always a physical length , ie when dealing with rotations that are dominant.

Implements KDL::Path.

Definition at line 100 of file path_circle.cpp.

Frame KDL::Path_Circle::Pos ( double s ) const [virtual]

Returns the Frame at the current path length s

Implements KDL::Path.
