Examples of Basic Iterative Algorithms for Inverse Kinematics.

A couple of examples showing the pseudo-inverse and Jacobian transpose inverting the kinematics.

Two simple models are provided showing the characteristics of basic iterative algorithms for the inversion of kinematics, namely the Jacobian transpose, its pseudo-inverse and the damped least-squares (DLS). The pro's and con's can be compared interactively for a serial two-links and a three-links chains. For the latter the gradient-projection method is also given to couple a secondary task exploiting the redundancy of the manipulator.
