  • Publication number: 20240077339
    Abstract: There is a method for measuring a deviation amount of a measuring device, comprising: transferring, by using a transfer device, the measuring device to a position in an area specified by transfer position data; acquiring measurement values using four or more sensor electrodes of the measuring device; identifying two or more sensor electrodes among the four or more sensor electrodes, the two or more sensor electrodes outputting, as the measurement values, capacitances that satisfy a reliability standard; and calculating the deviation amount based on the measurement values of the identified two or more sensor electrodes.

  • Publication number: 20230375371
    Abstract: A measuring system according to an exemplary embodiment acquires a measurement value indicating electrostatic capacitance between a measuring device and a transport fork for transporting the measuring device. The transport fork includes a target electrode. The measuring device includes a first sensor provided on a base board. The first sensor includes a central electrode and peripheral electrodes. The central electrode acquires electrostatic capacitance for reflecting a distance with the target electrode. The peripheral electrodes are disposed around the central electrode to acquire electrostatic capacitance for reflecting an amount of deviation in a horizontal direction with respect to the target electrode of the transport fork.

  • Publication number: 20220404222
    Abstract: A detector is a detector that detects fastening axial force applied by a fastening unit in an axial direction. The detector includes a strain element that has a through hole through which a bolt portion that the fastening unit has is inserted, and a strain sensing sensor that senses strain of the strain element. The strain element has a block-like form and has a planar portion following the axial direction on a side face thereof. The strain sensing sensor is provided on the planar portion.
