  • Patent number: 9327405
    Abstract: A robot apparatus that performs the work of attaching a cable includes a gripper that grips the cable having first and second ends, the first end being fixed; an arm main body that guides the second end of the cable being gripped by the gripper to the interior of a guide area; a force sensor that is provided on the arm main body and detects that the gripper has come into contact with the second end of the cable; a camera that captures an image of the guide area when the force sensor detects that the gripper has come into contact with the second end of the cable; and an image processor that detects the posture of the second end of the cable based on the captured image. The robot apparatus performs the work of attaching the cable in accordance with the detected posture of the connector.

  • Publication number: 20140350707
    Abstract: A robot system according to one aspect of an embodiment includes a robot and a control unit. The robot performs multi-axis operations based on instructions on the operations from the control unit. The control unit causes a power source to supply power to a partially fabricated item that includes a movable member that is able to be controlled by receiving power, and instructs the robot to perform an operation of attaching a predetermined member to the partially fabricated item while controlling the movable member.

  • Publication number: 20140283357
    Abstract: A workpiece assembly system includes a first manual station in which a person performs an operation of providing a first component set onto a pallet; a first robot station in which a robot performs an operation of assembling the first component set into a workpiece on a surface plate; and a conveyor that conveys the pallet and the surface plate from the first robot station to a subsequent manual station. After the robot has removed the first component set from the pallet and before the robot finishes the operation in the first robot station, the pallet is conveyed to the subsequent manual station prior to the surface plate.
