  • Patent number: 4831561
    Abstract: A work position error detecting apparatus comprises at least three one dimensional sensors for generating outputs dependent on a detected position of a work, where the one dimensional sensors are arranged so that directions in which the position of the work is detected is mutually different among the one dimensional sensors, a memory device for pre-storing outputs of each of the one dimensional sensors at a reference position of the work, and a computing unit for calculating and outputting a position error quantity of the work from the reference position based on outputs of the one dimensional sensors and the outputs of the one dimensional sensors at the reference position pre-stored in the memory device.

  • Patent number: 4716785
    Abstract: A playback industrial robot comprises at least one driving device provided with an electric motor having a motor shaft. The driving device comprises a reduction gear mechanism for reducing a rotational speed of the motor shaft of the motor, an output shaft for operating the robot, a clutch mechanism which is in a disengaged state when the output shaft rotates in a teaching mode so that the reduction gear mechanism does not act as a load, a mechanism for putting the clutch mechanism in an engaged state depending on supply and cutting off of the supply of compressed fluid when the teaching mode is started, and a case for accommodating the motor, the output shaft and the above mechanisms. The clutch mechanism comprises a movable clutch member applied with a rotary force depending on forward and backward rotations of the motor and guide members arranged in parallel to the output shaft at positions separated from a center of the output shaft toward an outer peripheral direction thereof.

  • Patent number: 4468695
    Abstract: A robot comprises a platform, a movable arm capable of moving to the platform for operation based on the information prestored in a memory, a working assembly provided movably to an end of the arm, means for detecting the deviation between a position for the working assembly and a position for a portion of a workpiece to be worked and means for displacing the working assembly to the arm so as to compensate the deviation detected by the detection means, and operates accurately.

  • Patent number: 4420812
    Abstract: A teaching-playback type robot is disclosed having a manipulator with a plurality of movable members connected to each other, a detector detecting the relative positions of the members, a switch for designating position signals from the detector upon a teaching operation, a memory for storing position signals from the detector, an interpolating arithmetic circuit for performing interpolating operation based on two position signals read out from memory upon playback operation.
