  • Publication number: 20250076890
    Abstract: The present application relates to a threshold-type obstacle recognition method, an orientation recognition method of a threshold-type obstacle, and a robot control method. With the robot control method of the present application, using the recognition results of the threshold-type obstacle and the recognition results of the orientation of the threshold-type obstacle, a corresponding operation of passing through the threshold obstacle is matched according to the relative relationship between a direction of travel of the robot and the orientation of the threshold-type obstacle, and the orientation of the threshold-type obstacle is used as a guide to provide the robot with a matching operation of passing through the threshold-type obstacle, so as to improve the success rate of the robot passing through the threshold-type obstacle.

  • Publication number: 20190296667
    Abstract: A reference determiner of a control device for a motor determines, at a predetermined period, a reference rotation angle of the motor as a command value to rotate the motor. When an actual rotation angle of the motor is delayed behind an immediately preceding reference rotation angle determined by the reference determiner and a delay amount is smaller than a predetermined threshold, the reference determiner determines a present reference rotation angle by adding an angle increment corresponding to rotating speed of the motor to the immediately preceding reference rotation angle, and, when the actual rotation angle is delayed behind the immediately preceding reference rotation angle and the delay amount is larger than the threshold, the reference determiner determines the immediately preceding reference rotation angle as the present reference rotation angle.
