		double	a,
		double	theta,

Member Function Documentation

robKinematics* robModifiedDH::Clone ( ) const

virtual

Clone.

Implements robKinematics.

vctFrame4x4<double> robModifiedDH::ForwardKinematics ( double q ) const

virtual

Get the position and orientation of the coordinate frame.

Returns the position and orientation of the coordinate frame.

Parameters

joint The joint value

Returns: The position and orientation of the coordinate frame

Implements robKinematics.

double robModifiedDH::GetRotationX ( ) const

inline

double robModifiedDH::GetRotationZ ( ) const

inline

double robModifiedDH::GetTranslationX ( ) const

inline

double robModifiedDH::GetTranslationZ ( ) const

inline

vctMatrixRotation3<double> robModifiedDH::Orientation ( double q ) const

virtual

Get the orientation of the link.

Returns the orientation of the link with respect to the proximal link for a given joint vale.

Parameters

joint The joint associated with the link

Returns: The orientation associated with the DH parameters

Implements robKinematics.

vctFixedSizeVector<double,3> robModifiedDH::PStar ( ) const

virtual

Return the position of the next (distal) link coordinate frame.

This method returns the $XYZ$ coordinates of the origin of the distal link in the coordinate frame of the proximal link. "PStar" is not a good name for this but the literature uses $ {p}^* $ to denote this value.
