  • Publication number: 20090018700
    Abstract: A robot arm is provided with an end effecter for grasping an object and a force sensor for detecting a force acted upon the end effecter. In the state in which end effecter grasps an object, when there is a change in the force acting on the end effecter detected by the force sensor, outputted is a signal for releasing the force of the end effecter grasping the object. The object grasped by the end effecter can be taken out as if the object were handed from person over to person.
