Abstract

A robot hand has a plurality of fingers including a contact sensing finger that senses contact with an object. A base provided with the fingers detects a resultant reaction force that is the combination of reaction forces from the fingers. When no resultant reaction force is detected, the plurality of fingers are moved toward the object, and when the contact sensing finger comes into contact with the object, a force that drives the fingers is switched to a force corresponding to a grasp force. When the contact sensing finger has not come into contact with the object but a resultant reaction force is detected, the driving of the fingers is terminated and the position of the base is corrected by moving the base in a direction in which the resultant reaction force having acted thereon is not detected any more.
