  • Patent number: 7957838
    Abstract: A control system for a plurality of mechanical units, namely robots and/or external axes. A manually-operated control, such as a joy-stick or key panel, is adapted to move at least one of the mechanical units or part thereof. The control system includes an indicator adapted to indicate whether the at least one mechanical unit or part thereof that is to be moved is associated with any other mechanical unit(s) or part(s) thereof and consequently indicate that movement of the at least one mechanical unit or part thereof will also result in the movement of the indicated associated mechanical unit(s) or part(s) thereof.
    Type: Grant

  • Patent number: 6467178
    Abstract: A method and system for determining a tool center point (TCP) for a beam tool involves the use of a specially design aperture and light sensing device. The method and system oscillates the beam tool across an aperture assembly such that light from the tool periodically passes through the aperture assembly. Center point coordinate information is then determined based on passage of light through the aperture assembly. The method and system further provides for calculating the TCP based on the center point coordinate information.
