  • Patent number: 8757691
    Abstract: A hand includes: a pair of supporters; first and second gripping claws which are supported inside of the pair of supporters, respectively, so as to grip a bolt; an oscillating mechanism which oscillates the first and second gripping claws on an oscillatory axis crossing a longitudinal direction of each of the supporters, so as to change the orientation of a tip of each of the first and second gripping claws; and a bolt rotating mechanism for rotating, on the axis of the bolt, the bolt gripped by the first and second gripping claws.

  • Publication number: 20140125080
    Abstract: An end effector includes a holding unit that holds a screw member to be rotatable around the axis line of the screw member, and a rotary unit that is provided on the axis line, moves linearly along the axis line in a condition of being in contact with the head portion of the screw member held by the holding unit, and rotates the screw member around the axis line by rotation accompanying the linear motion.

  • Patent number: 8616599
    Abstract: A hand according to an embodiment includes a pair of supporting units, a pair of capturing claws, an opening-and-closing mechanism, and a reciprocating mechanism. The pair of capturing claws are supported on the inner surfaces of the pair of respective supporting units and capture a part. The opening-and-closing mechanism opens and closes the pair of supporting units along a reciprocating axis intersecting with longitudinal directions of the supporting units. The reciprocating mechanism causes the pair of capturing claws to rotate about the reciprocating axis to change the direction of each tip of the capturing claws.
