Abstract :
The control of kinematically redundant manipulators using only pseudoinverse control is known to produce drift in joint space when a cyclic task is performed in rectilinear space. The properties of this drift are examined by performing numerical experiments. This drift has predictable properties including a numerically stable limit in some situations. At this limit the arc length of the path in joint space appears to be near a minimum
