Configuration of a JointRotation.

Constructor & Destructor Documentation

hpp::model::RotationJointConfig::RotationJointConfig ( size_type configSize )

Constructor.

Parameters:

configSize dimension of the joint configuration size: used to resize the vector of bounds.

virtual hpp::model::RotationJointConfig::~RotationJointConfig ( ) [virtual]

Member Function Documentation

virtual void hpp::model::RotationJointConfig::difference	(	ConfigurationIn_t	q1,
		ConfigurationIn_t	q2,
		const size_type &	indexConfig,
		const size_type &	indexVelocity,
		vectorOut_t	result
	)		const `[pure virtual]`

Difference between two configurations.

Parameters:

q1	configuration,
q2	configuration,
indexConfig	index of first component of q corresponding to the joint.
indexVelocity	index of first component of v corresponding to the joint

Return values:

result[indexVelocity] component of vector representing the difference between q1 and q2.

If joint is bounded:

$\texttt{result}[\texttt{index}] = \textbf{q}_1[\texttt{index}] - \textbf{q}_2[\texttt{index}]$

If joint is not bounded:

$\texttt{result}[\texttt{index}] = \textbf{q}_1[\texttt{index}] - \textbf{q}_2[\texttt{index}] + 2k\pi$

where $k$ is such that $\texttt{result}[\texttt{index}]$ lies between $-\pi$ and $\pi$ .

Implements hpp::model::JointConfiguration.

virtual value_type hpp::model::RotationJointConfig::distance	(	ConfigurationIn_t	q1,
		ConfigurationIn_t	q2,
		const size_type &	index
	)		const `[pure virtual]`

Distance between two configurations of the joint.

Parameters:

q1,q2	two configurations of the robot
index	index of first component of q1 and q2 corresponding to the joint.

Returns:: the angle between the joint orientations

Implements hpp::model::JointConfiguration.

virtual void hpp::model::RotationJointConfig::integrate	(	ConfigurationIn_t	q,
		vectorIn_t	v,
		const size_type &	indexConfig,
		const size_type &	indexVelocity,
		ConfigurationOut_t	result
	)		const `[pure virtual]`

Integrate constant derivative during unit time.

Parameters:

q	initial configuration
v	joint velocity
indexConfig	index of first component of q corresponding to the joint.
indexVelocity	index of first component of v corresponding to the joint

Return values:

result write joint configuration in result [indexConfig:indexConfig + joint config size]

Note:: if result is beying bounds, return active bound.

Implements hpp::model::JointConfiguration.

virtual void hpp::model::RotationJointConfig::interpolate	(	ConfigurationIn_t	q1,
		ConfigurationIn_t	q2,
		const value_type &	u,
		const size_type &	index,
		ConfigurationOut_t	result
	)		`[pure virtual]`

Interpolate two configurations of the joint.

Parameters:

q1,q2,two	configurations to interpolate
u	in [0,1] position along the interpolation: q1 for u=0, q2 for u=1
index	index of first component of q1 and q2 corresponding to the joint.

Return values:

result write joint configuration in result [index:index+nb dofs]

q1 and q2 are configurations of the robot where coordinates between index and index + number of dofs - 1 correspond to the configuration of the joint:

a real value for translation joint and bounded rotation joints,
an angle for unbounded rotation joints,
x, y, z, roll, pitch, yaw for freeflyer joints.

Implements hpp::model::JointConfiguration.

virtual void hpp::model::RotationJointConfig::uniformlySample	(	const size_type &	index,
		ConfigurationOut_t	result
	)		const `[pure virtual]`

Uniformly sample the configuration space of the joint.

Parameters:

index index of first component of q corresponding to the joint.

Return values:

result write joint configuration in result [index:index+nb dofs]

Implements hpp::model::JointConfiguration.
