Detailed Description

Implementation of a inverse velocity kinematics algorithm based on the generalize pseudo inverse to calculate the velocity transformation from Cartesian to joint space of a general KDL::Chain.

It uses a svd-calculation based on householders rotations.

Constructor & Destructor Documentation

KDL::ChainIkSolverVel_pinv::ChainIkSolverVel_pinv ( const Chain chain,
double  eps = 0.00001,
int  maxiter = 150 
)

Constructor of the solver.

Parameters:
chain the chain to calculate the inverse velocity kinematics for
eps if a singular value is below this value, its inverse is set to zero, default: 0.00001
maxiter maximum iterations for the svd calculation, default: 150
