  • Patent number: 11931895
    Abstract: A robot control system includes circuitry configured to: determine a necessity of assisting a robot to complete an automated work, based on environment information of the robot; select a remote operator from candidate remote operators based on stored operator data in response to determining that it is necessary to assist the robot to complete the automated work; transmit the environment information to the selected remote operator via a communication network; receive an operation instruction based on the environment information from the selected remote operator via the communication network; and control the robot to complete the automated work based on the operation instruction.

  • Patent number: 7029224
    Abstract: A method for transferring a thin plate is provided, in which three or more grasping claws of a transfer arm grasp the periphery of the thin plate in order to transfer it to a predetermined transfer position, and three or more holding claws hold the periphery of the thin plate in the transfer position. The transfer arm rotates about a shaft which is in a direction of a vector sum of a first vector perpendicular to a surface of the thin plate before transfer, and a second vector perpendicular to the surface of the thin plate after the transfer, to transfer the thin plate with changing the posture thereof.

  • Patent number: 6763319
    Abstract: A stylus having a curvature radius of 1 mm or less is attached to the extremity of a probe. When the profile of an object is measured with high precision by causing the stylus to follow a measurement surface of the object, a reference ball for calibration is first measured, thereby surface profiling the object. From the measurement data, a contact position where the stylus contacts with the object is determined. A positional error caused by a curvature radius of the stylus is corrected by using an angle of inclination of the measurement surface in that contact position. The amount of profile error in the contact position is extracted by using the profile error data pertaining to the stylus determined by measurement of the reference ball. The amount of profile error is added to the measurement data, thereby correcting the profile error caused by the curvature radius of the stylus.

  • Patent number: 6480286
    Abstract: Optical displacement gauges 20 are respectively arranged on both sides of a thin sheet material w, and displacement of surface position of the thin sheet material w is measured by irradiating measurement light L1 to the surface of the thin sheet material w. Thickness variation of the thin sheet material w is obtained from the measurement results of displacement of the surface position of the thin sheet material w.

  • Patent number: 6026583
    Abstract: A shape measuring apparatus includes an object measuring device, a holding base, a reference plane measuring device, and a length measuring unit. The holding base holds an object-to-be-measured on its surface and has a reference plane provided on its back side so that a measured surface of the object and the reference plane can be simultaneously scanned by the object measuring device and the reference plane measuring device, respectively. Therefore, the object and the reference plane can sway integrally with each other, and the accuracy of measurement of the measured surface is not influenced by any moving straightness deviation of the holding base unless any change occurs in relative positions of the reference plane and the measured surface. Therefore, the shape of the measured surface can be measured with the flatness accuracy of the reference plane.

  • Patent number: 5616916
    Abstract: Substantially collimated displacement detection light is led to a first lens and condensed by the first lens to proximities to a reflecting surface of a probe. The reflected light is displaced by an atomic force acting against a surface of a sample, where the reflected light varies in reflection angle according to the displacement. The displaced light is lead to the first lens, changed in direction by a mirror, and detected by magnifying the displacement of the probe.
