Mami YOMODA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Robot control device, robot control method, and robot control program
    Patent number: 11813755
    Abstract: A robot control device according to the present invention is configured to: detect a collision of a robot with an object at a predetermined collision detection sensitivity; perform control of operating the robot, and stopping the robot when a detection part detects the collision; and decrease, when a predetermined circumstance causing the robot to have a low temperature is satisfied, the collision detection sensitivity compared to when the predetermined circumstance is unsatisfied.
    Type: Grant

  • Vibration suppression device, method and computer-readable medium using estimated vibration torque
    Patent number: 11669055
    Abstract: A vibration suppression device that suppresses vibration of an operation unit in a mechanical system having a natural vibration mode including the operation unit, an actuator unit that operates the operation unit, and an elastic body that couples the operation unit and the actuator unit, the vibration suppression device including a generation means for generating a drive signal for driving the actuator unit, an estimation means for estimating a measurement amount related to the mechanical system, a correction means for correcting the drive signal generated by the generation means on the basis of the measurement amount estimated by the estimation means, and a change means for changing a gain used by the estimation means so that an influence of an increase in a modeling error becomes small in a period in which the modeling error of the mechanical system increases.
