Summary:This paper describes a novel approach of robust motion control of
a redundant manipulator by projection planes. In the proposed approach,
a robust controller based on a workspace observer is employed in the
selectable projection plane. Then, an adequate selection of the
projection planes makes it possible to simplify the controller without
deteriorating the tip motion response and to obtain the desired motion
in the null space of the manipulator. This is one of the remarkable
features of the proposed approach. The validity of the proposed
controller is confirmed by several numerical simulations
