  • Patent number: 10668620
    Abstract: In an industrial robot, correction is made for change in position and attitude of an arm distal end due to mechanical deflection of the robot. In the robot, a moment applied to the first axis in its non-rotation direction opposite to its rotation direction is calculated from a load torque applied to the second axis in its rotation direction, a moment due to a second-axis-side self-weight, and a ratio of a distance between the rotation centers of the first and second axes, to a distance between the rotation centers of the second axis and a tool. A deflection amount indicating an angle of the first axis tilting in the non-rotation direction is calculated from the moment applied to the first axis and the rigidity of the first axis in the non-rotation direction. A control value is corrected based on the deflection amount to control the robot.

  • Publication number: 20200167536
    Abstract: An optical information reader includes a reflective member that reflects illumination light emitted from an illuminant toward a reading surface, and an image former ensured to present an imaging target held over the reading surface within an imaging region of an imager. The imaging region includes a first imaging region defined between the image former and the reading surface, and a second imaging region defined between the reading surface and the reflective member so as to be continuous to the first imaging region when light is internally reflected on the reading surface inside the housing. The reflective member is arranged outside the first imaging region, while the illuminant, the imager and the image former are arranged outside the second imaging region. The illuminant emits illumination light toward a reflecting surface of the reflective member in the second imaging region.

  • Patent number: 10649084
    Abstract: An object detection apparatus measures a distance to a detected object at each irradiation angle, based on reflected waves of electromagnetic waves irradiated from a laser light irradiating unit at each irradiation angle. The apparatus determines whether the measured distance remains unchanged for prescribed period of time, for each irradiation angle, and stores the determined distance in a storage unit as a stationary object distance in association with the irradiation angle. The apparatus compares the current measured distance and the stored distances, and determines whether a stationary object distance matching the current distance is present among the stored distances.

  • Patent number: 10621395
    Abstract: In a configuration for detection of a movement state of a radio tag using a phase difference of a response wave from the radio tag, a phase ?[i] and a measurement time t[i] of a response wave from a radio tag measured are sequentially stored in a memory. A difference from a previous phase and a difference from a previous measurement time with respect to each phase ?[i] stored in the memory are calculated as a phase difference ??[i] and a time difference ?t[i]. A phase addition value ?sum[i] obtained by cumulatively adding a plurality of the phase differences ??[i] is calculated so as to correct a phase difference in which the corresponding time difference ?t[i] among the calculated plurality of the phase differences ??[i] exceeds a time threshold tsa [i], whereby the movement state of the radio tag is detected based upon the calculated phase addition value ?sum[i].

  • Publication number: 20200086488
    Abstract: There is provided a method and an apparatus for controlling a robot arm. In this control scheme, a position error indicating a deviation between a command position, which is a control target position, and a current position, which is a position where the arm of the robot is currently located, is acquired. When the acquired position error exceeds a threshold, a new corrected command position between the current position and the command position is set. After the arm of the robot is moved to the corrected command position, a new corrected command position reset between the corrected command position serving as a new current position and the command position. Reconfiguration of a corrected command position is iterated until a current position of the robot arm becomes equal to the command position so that movement of the robot arm is achieved from the current position to the command position.

  • Patent number: 10495617
    Abstract: A controller as a CO2 sensor reference value calibration apparatus calibrates a reference value of the CO2 sensor in the following manner. Introduction of outside air is started after a person is not detected. A CO2 concentration, which is acquired when a preset first waiting time elapses, is set as a provisional reference value. The carbon dioxide concentration, which is acquired when a preset second waiting time elapses, is compared with the provisional reference value. In a case where a change rate of the carbon dioxide concentration is out of a preset allowable range, the carbon dioxide concentration is acquired when the second waiting time elapses after newly setting the acquired carbon dioxide concentration as the provisional reference value. In a case where the change rate of the carbon dioxide concentration is in the allowable range, the currently set provisional reference value is set as the reference value.

  • Patent number: 10473347
    Abstract: On the screen of a display unit, period border lines are displayed. The period border lines divide hours (for example 24 hours) for a user's desired one day into a plurality of periods and present line segments movable on the screen in a predetermined direction. Each of the line segments acts as a border lien between mutually adjacent periods. On the screen, target temperatures which are set for the respective periods are also displayed. Dragging the period border liens (K1 to K4) so as to move on the screen makes it possible to move a start time and a stop time of mutually adjacent periods are changed simultaneously. In addition to this change, target temperatures which were set before the change are reset for changed periods.
