This paper describes a new formulation of the equations of motion for a system of connected rigid bodies. The bodies may either be hinge or slide connected. The connection topology is assumed to be that of a tree. Starting with the Newton-Euler equations of motion, the equations are transformed into a new system of equations using generalized velocity coordinates (both translational and rotational). The selection of these generalized coordinates is what sets this development apart from others. Constraint forces and/or torques that do not work are isolated and eliminated from the equations of motion. The generalized velocities are reduced to a minimum set. The vector operator equations of motion give a set of nonlinear differential equations that are amenable to standard numerical integration techniques.
