  • Method and apparatus for positioning a robot at start-up, electronic device and storage medium
    Patent number: 11579613
    Abstract: A method for positioning a robot at start-up includes: when the robot is started up, controlling the robot to rotate in a preset rotation direction in a start-up positioning region; determining position information about a rotation path of the positioning transmitting unit according to the preset rotation direction and a set of at least three different position distances, where the at least three different position distances are between the positioning transmitting unit and the two positioning receiving units disposed at the different fixed positions and are determined during a rotation process; using a direction extending from the center position of the rotation path to a position of the positioning transmitting unit when the robot stops rotation as orientation information of the robot; and using the center position of the rotation path and the orientation information of the robot as start-up positioning information of the robot.
