    Abstract

    This work adds some new insight into the singularity-consistent parameterization of the inverse kinematics of a nonredundant robot, tracking a reference path. We show that in the general case (e.g. motion with constant end-effector velocity on the path) there is an non-integrable motion component. When the end-effector moves with a velocity proportional to the determinant of the Jacobian, the non-integrable motion component is removed. In the same time, the order of the equation of motion is reduced. We call this type of motion `natural.' Further on, from the simplified equation of natural motion, we derive the mechanical power measure. This is an instantaneous-motion performance measure defined over the phase space of the system, and thus, can be useful to evaluate the dynamic performance for the specified instantaneous motion direction.
