Detailed Description

represents both translational and rotational acceleration.

This class represents an acceleration twist. A acceleration twist is the combination of translational acceleration and rotational acceleration applied at one point. represents the combination of a force and a torque.

This class represents a Wrench. A Wrench is the force and torque applied at a point

Wrench KDL::Wrench::RefPoint

(

const Vector &

v_base_AB

[inline, static]

Returns:

a zero Wrench

bool Equal	(	const Wrench &	a,
		const Wrench &	b,
		double	eps
	)		[friend]

do not use operator == because the definition of Equal(.,.) is slightly different. It compares whether the 2 arguments are equal in an eps-interval

friend class Frame [friend]

Definition at line 952 of file frames.hpp.

bool operator!=	(	const Wrench &	a,
		const Wrench &	b
	)		[friend]

The literal inequality operator!=().

Wrench operator*	(	const Wrench &	lhs,
		double	rhs
	)		[friend]

Scalar multiplication.

Wrench operator*	(	double	lhs,
		const Wrench &	rhs
	)		[friend]

Scalar multiplication.

Wrench operator+	(	const Wrench &	lhs,

Wrench operator-

)

[friend]

An unary - operator.

Wrench operator/	(	const Wrench &	lhs,
		double	rhs
	)		[friend]

Scalar division.

bool operator==	(	const Wrench &	a,

void SetToZero

(

)

[friend]

Sets the Wrench to Zero, to have a uniform function that sets an object or double to zero.
