Abstract
Based on the reciprocal screw theory, this paper discusses the distribution of the rotational axes in space when the reciprocal screw is a screw (h≠0), analyses in particular the kinematic characteristics of a five-DOF series robot-Motoman, and presents its 5 kinds of kinematic atlas in different conditions.
