          dataglove as master devices. The operator mimics one of the predetermined
          grasp shapes with the dataglove, and the task selector detects it. The operator
          can present a desired relative rotational and translational motion for manip-
          ulation during the precision grasp with the Phantom Omni. As shown in
          Fig. 8.11, we executed grasping and manipulation of two objects with
          the supervisory controller. First, an operator put the dataglove on his hand
          and made a precision grasp shape to grasp a spray can with the hand, and
          grasp and rotate the tip of the Phantom Omini around the yaw axis to rotate
          the spray can. Then, the hand stably rotated it, as shown in Fig. 8.11A. Next,
          the operator made a precision grasp shape to grasp a box, and grasped and
