    摘要: A gripping device which simulates the action of a human finger comprises three pivotted sections 3, 5, 7 having the middle section 5 linked to the top section 7 by a bar 9 so that its rotation causes rotation of the tip section. Rotation of the lower section 3 is preferentially effected by a motor 11 via a sliding cross-head 15, an equaliser bar 18 and a rod 19. If this rotation is stopped by an object 25 to be gripped, the drive transfers via rod 20, crank 21 and rod 23 to the middle section 5, causing the middle and tip sections to rotate and grip the object against the lower portion as shown at 26. A robotic hand comprising four such fingers and a thumb is usable as a substitute for a human hand in a glove-box glove.

    摘要: An accurate high speed gripper assembly (12) for use in handling articles in an automated manu­facturing process. The gripper assembly (12) includes a pair of movable fingers (14, 15) which depend from movable carriages (18, 19) mounted in a housing (13) rotatably mounted on the end of a robot arm (11). A pair of stepper motors (31, 33) are mounted in the housing (13) and are connected to rotary actuators (26, 27) which displace the fingers (14, 15) in discrete incremental steps toward or away from one another when rotated. Compliant elements (51) provided on each finger cooperate with force/torque sensors (52, 53) for determining the proximity of the fingers to an article to be gripped and the gripping force applied by the fingers (14, 15). The sensors (52, 53) generate signals which are processed in a controller (35) that regulates operation of the stepper motors (31, 33) so as to achieve desired finger move­ments and gripper forces.

    摘要: A control apparatus includes a hand controller that controls a hand capable of grasping an object to be grasped and including a plurality of sensors. The hand controller is configured to be able to obtain information regarding grasping force acting on the object to be grasped from the hand or information regarding a moment acting on the object to be grasped in the hand, the information regarding the grasping force and the information regarding the moment being based on outputs of the plurality of sensors. The hand controller estimates, on a basis of the information regarding the grasping force or the information regarding the moment, a grasping state in which the hand is grasping the object to be grasped.
