This paper proposes an algorithm, for calculating the inverse dynamics of link manipulators. First, we derive a method to calculate the inverse dynamics of a general type of parallel link mechanism using the method proposed by Luh and Zeng., which is developed for a simple closed link mechanism and yields the inverse dynamics of the simple closed link mechanism using the Newton-Euler method of serial link manipulators. We then derive a calculation algorithm for the inverse dynamics of a Stewart Platform. The algorithm is applied to a dynamic simulation of a Stewart Platform by a unit-vector method, and the simulation results demonstrate the validity of the method.
