  • Publication number: 20250058466
    Abstract: A robot control system includes: an impedance control unit configured to, while a robot holding a container with an arm is moving at a first speed, make prediction about displacement of a liquid in the container that occurs when a speed of the robot is changed to a second speed higher than the first speed, and control a magnitude of a first impedance of the arm in a horizontal direction based on a result of the prediction; and a movement control unit configured to change the speed of the robot to the second speed in response to reduction in the first impedance.

  • Publication number: 20240286291
    Abstract: A position inspection system includes a gripping unit that grips an object, a shooting unit that shoots an inspection image of the object gripped by the gripping unit, and a processor. The processor identifies a first rotational amount of the object from the proper position within a plane of the inspection image. The processor identifies, based on control information of the gripping unit, a correction angle between a direction in which a particular portion of the object is facing and a shooting direction of the inspection image. The processor identifies, based on the first rotational amount and the correction angle, a second rotational amount of the object from the proper position about the direction in which the particular portion of the object is facing.

  • Patent number: 11639002
    Abstract: The control system is a control system that controls a connection between an autonomous mobile robot and a base station, the control system including: a radio communication unit that communicates with the base station; and a connection control unit that performs control, in a connection of communication performed by the radio communication unit, when a radio wave shielding object which the autonomous mobile robot is able to pass through is on a path along which the autonomous mobile robot is to move, so that the autonomous mobile robot is prompted to connect to a predetermined base station of which a received radio wave intensity at a position on the path in front of the shielding object is affected by the shielding object.

  • Patent number: 11230019
    Abstract: A posture angle calculation apparatus 170 includes an acquisition unit 171 configured to acquire an output of an acceleration sensor 151 installed to output acceleration of a moving apparatus that moves along a moving surface in a vertical axis direction with respect to the moving surface and to acquire an output of a gyro sensor 152 installed to output an angular velocity about the vertical axis. The posture angle calculation apparatus 170 further includes a calculation unit 172 configured to assume, when the acceleration is larger than reference acceleration Rg, and the angular velocity is smaller than a preset reference angular velocity Rw, the angular velocity ?z is zero and calculate a posture angle of the moving apparatus about the vertical axis. The posture angle calculation apparatus 170 further includes an output unit 173 configured to output data of the calculated posture angle.
