TRAC-IK is a faster, significantly more reliable drop-in replacement for KDL's pseudoinverse Jacobian solver. The TRAC-IK library has a very similar API to KDL's IK solver calls, except that the user passes a maximum time instead of a maximum number of search iterations. Additionally, TRAC-IK allows for error tolerances to be set independently for each Cartesian dimension (x,y,z,roll,pitch.yaw).
