Abstract
A manipulator device has an arm portion and a hand portion The hand portion includes one or more finger portions that manipulate a target object. Each finger portion includes a slip sensor and multiple contact sensors, with at least one contact sensor at a position proximate to the slip sensor and at least another contact sensor at a position remote from the slip sensor. When the contact sensors at the positions remote from the slip sensor detect contact of the target object and the contact sensors arranged at the positions proximate to the slip sensors do not detect contact, a position of the finger portion is moved by a distance corresponding to the distance between the contact sensors detecting contact of the target object and the contact sensors arranged at the positions proximate to the slip such that a detecting position of the slip sensor is coincident with a position of the target object.
