    Abstract: A robot hand having a suction holding unit on one face side holds a plate-shaped work by suction. An outer circumferential edge of the plate-shaped work is held, without contact with a surface of the plate-shaped work, by an outer circumference holding unit provided on the other face side. The robot hand can be used to hold the plate-shaped work yet to be worked by the suction holding unit, and to hold the plate-shaped work having been worked by the outer circumference holding unit. This prevents working debris from being deposited on the plate-shaped work yet to be worked and prevents defective working from occurring. In addition, since the plate-shaped work having been worked is held by the outer circumference holding unit, the robot hand does not make contact with surfaces of the worked plate-shaped work, and, accordingly, no contact marks are formed on the surfaces of the work.

    Abstract: The positions and orientations of one or more target objects are obtained from the result of measuring a set of target objects by using a first sensor. A robot including a grip unit is controlled to grip one target object as a gripping target object among the target objects by the grip unit. Whether the grip unit has succeeded in gripping the gripping target object is determined from the result of measurement performed by a second sensor for measuring the target object gripped by the grip unit. When the grip unit has been determined to fail in gripping the gripping target object, one target object interacting with the gripping target object is selected among the target objects. The robot is controlled to grip the selected target object by the grip unit.

The tanks have submerged metal fixtures which temporarily support the parts, and each fixture in the electroplating tank is individually connected to a direct current power source through a corresponding timer switch controlled by the computer so that each part is plated for a precise time period independently of the time the part remains in the plating solution. Each fixture is coated with an insulation material and has a base with metal contact with a removable fixture member having limited metal line contact with the supporting part. A plurality of electroplating lines each include the above components, and common tanks in the lines receive an electroplating solution recirculated through a common filter and service tank where the solution is heated and controlled.

  • Patent number: 8287017
    Abstract: When dishes are held by means of a robot hand (10), its fixed side engaging plate (13) and movable side engaging finger (14) are moved under horizontal state toward a dish (20) to be handled, and the outer circumferential edge side portion of the dish (20) is inserted between them. The distal end portion (14b) of the movable side engaging finger (14) is then bent by a predetermined amount to the side of the dish (20) and the robot hand (10) is raised. Consequently, the dish (20) is brought into a state where it is held by its own weight between the fixed side engaging plate (13) and the movable side engaging finger (14). Thereafter, the right and left first finger units (15, 16) are bent to the side of the dish (20) and the dish (20) is pushed by their dish pushing faces (15g, 16g), thus bringing about such a state as the dish (20) is held surely between the fixed side engaging plate (13) and the movable side engaging finger (14).

  • Patent number: 8280551
    Abstract: A manipulator includes at least one camera capable of observing an end effector from a direction suitable for work. A rotating portion rotatable coaxially with the end effector is provided to a link adjacent to a link located at a manipulator tip end. At least one camera for recognizing a work piece as an object is arranged on the rotating portion through a camera platform. An actuator for controlling a rotation angle of the rotating portion is driven according to a rotation angle of the link located at the manipulator tip end, and thus the camera is arranged in a direction perpendicular to a plane where the end effector can move when the end effector performs a grip work. In an assembly work, the rotating portion is rotated such that the camera is arranged in a direction parallel to the plane where the end effector can move.

  • Publication number: 20120143084
    Abstract: A hand held robotic system that remains stiff so long as it is operating within allowed limits, but which become actively controlled once the operator exceeds those limits. The system thus corrects deviations by more than a predetermined amount of the operator's hand motions, so that the tool remains in the allowed region even when the operator's hand deviates from the planned trajectory. The pose and path of the robotic operating head is ascertained by means of a navigation or tracking system, or by means of a proximity device to measure the closeness of the operating head to a damage sensitive feature. As the tool deviates from its predetermined path or pose, or comes too close to the hazardous area, the robot control acts to move the tool back to its predetermined pose or path, or away from the hazardous region, independently of user's hand movement.
