    Abstract

    The dynamic equations of a parallel manipulator have a parallel structure. This paper shows that this parallelism gives rise to a recursive formula for the inverse of the inertia matrix of the manipulator. The formula generally requires no numerical methods, which are often used for calculating the inverse of the matrix; therefore, the formula is expected to yield high numerical accuracy. It is also shown that in some special cases, the formula does not involve any matrix inversion at all.
