◆ calculateJointVelocities()

int8_t ConstraintSolverFactory::calculateJointVelocities	(	Matrix6Xd_t &	jacobian_data,
		const Vector6d_t &	in_cart_velocities,
		const JointStates &	joint_states,
		Eigen::MatrixXd &	out_jnt_velocities
	)

Calculation of new joint velocities according to current joint positions and cartesian velocities.

Parameters

params	References the inv. diff. kin. solver parameters.
jacobian_data	References the current Jacobian (matrix data only).
in_cart_velocities	The input velocities vector (in cartesian space).
joint_states	The joint states and history.
out_jnt_velocities	The calculated joint velocities as output reference.

Returns: The calculated new joint velocities in (m x 1)-Matrix.

Out of the parameters generates a damping method (e.g. constant or manipulability) and calculates the damping factor. Dependent on JLA active flag a JointLimitAvoidanceSolver or a UnconstraintSolver is generated to solve the IK problem. The objects are generated for each solve-request. After calculation the objects are deleted.
