When it is desired to drive a musculo-skeletal model from measured marker trajectories from a motion capture experiment, it is very often the case that the resulting set of kinematic equations is over-determinate and the solution set is empty. To accommodate this problem, some compromise has to be made, i.e. either by excluding some of the measured markers from consideration or allowing some of the equations to be violated. In this webcast, we will demonstrate a general method for handling over-determinate mechanical systems. The presented formalism includes forward- and inverse- kinematics as special cases and also allows for analysis of both open and closed kinematic chains.
