  • Patent number: 8954182
    Abstract: A robot system includes a manipulator; a work table arranged within a movement extent of the manipulator; an imaging unit for taking a two-dimensional image of the workpieces loaded on the work table; a workpiece supply unit for supplying workpieces onto the work table; and a control system for controlling operations of the manipulator and the imaging unit. The control system includes an imaging control unit for controlling the imaging unit to take the two-dimensional image of the workpieces loaded on the work table, a workpiece detecting unit for detecting a position and a posture of each of the workpieces loaded on the work table by comparing the two-dimensional image taken by the imaging unit with templates stored in advance, and a manipulator control unit for operating the manipulator to perform a work with respect to the workpieces detected by the workpiece detecting unit.

  • 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.
