  • Publication number: 20190160664
    Abstract: A vibration suppression device acquires a teaching position, computes a speed plan based on the acquired teaching position and a first acceleration/deceleration parameter, computes data related to deflection occurring during an acceleration/deceleration operation of a robot based on the teaching position and the speed plan, and acquires data indicating a posture at the teaching position. Further, a machine learning unit of the vibration suppression device estimates an acceleration/deceleration parameter with respect to the data related to the deflection and the data related to the posture using the data related to the deflection and the data related to the posture as input data.

  • Publication number: 20190113106
    Abstract: A rotary actuator has: one motor, two strain wave reduction gears disposed symmetrically on both sides of the motor, and one output shaft. The output rotation of the motor is reduced in speed at the same reduction ratio by the two strain wave reduction gears and is outputted from the output shaft to a load side. The first and second externally toothed gears of the first and second strain wave reduction gears are flexed into ellipsoidal shapes with 90 degrees shifted in phase, and are meshed with first and second internally toothed gears. The angle transmission errors of the first and second strain wave reduction gears transmitted to the output shaft are reduced by cancelling each other out in the output shaft. Reduced-speed output rotation that has the reduced angle transmission errors is outputted to the load side from the output shaft.

  • Patent number: 10140577
    Abstract: A non-transitory computer-readable recording medium contains an event processing control program for event processing that processes received event data in accordance with processing rules and outputs output data. The program causes a computer to execute a process that includes obtaining first assessment values pertaining to output data by the event processing for a first type of events, periodically by a first period. A correlation coefficient value of first and second received event data is periodically calculated by a second period longer than the first period. The first and second received event data are received event data of the first type and of a second type different from the first type, respectively. A second filtering condition pertaining to the second received event data is set based on the correlation coefficient value and a first filtering condition that pertains to the first received data and is specified from the assessment values.

  • Patent number: 9684722
    Abstract: According to one embodiment, an output unit performs filtering on input data for each filtering condition for performing data filtering and outputs a result of the filtering to an output destination. A receiving unit receives information indicating whether the output result of the filtering is appropriate or inappropriate from the output destination. A cumulative counting unit cumulatively counts the numbers of times determined to be appropriate and appropriate for each filtering condition based on the received information. A switching unit switches the filtering at the output unit between being valid and invalid for each filtering condition based on cumulative values of the numbers of times the output result of the filtering for each filtering condition has been determined to be appropriate and inappropriate and a switching condition that switches the filtering condition between being valid and invalid.
