Detailed Description

Implementation of a general inverse position kinematics algorithm based on Newton-Raphson iterations to calculate the position transformation from Cartesian to joint space of a general KDL::Tree. Takes joint limits into account.

◆ TreeIkSolverPos_NR_JL()

KDL::TreeIkSolverPos_NR_JL::TreeIkSolverPos_NR_JL ( const Tree tree,
const std::vector< std::string > &  endpoints,
const JntArray q_min,
const JntArray q_max,
TreeFkSolverPos fksolver,
TreeIkSolverVel iksolver,
unsigned int  maxiter = 100,
double  eps = 1e-6 
)

Constructor of the solver, it needs the tree, a forward position kinematics solver and an inverse velocity kinematics solver for that tree, and a list of the segments you are interested in.

Parameters
treethe tree to calculate the inverse position for
endpointsthe list of endpoints you are interested in.
q_maxthe maximum joint positions
q_minthe minimum joint positions
fksolvera forward position kinematics solver
iksolveran inverse velocity kinematics solver
maxiterthe maximum Newton-Raphson iterations, default: 100
epsthe precision for the position, used to end the iterations, default: epsilon (defined in kdl.hpp)
Returns
