  • Robot recharging localization method and robot using the same
    Patent number: 11422567
    Abstract: The present disclosure provides a robot recharging localization method including: calculating a directional angle of a first identification line based on identification points near a radar zero point of the first recognition line collected by a radar of the robot; determining a sequence of the identification points in an identification area according to the calculated directional angle of the first identification line, and finding two endpoints of the sequence of the identification points; determining dividing point(s) in the sequence of the identification points; fitting the sequence of the identification points to obtain a linear equation of the first identification line with respect to a coordinate system of a mobile robot; and determining a central positional coordinate of the first identification line based on the dividing point(s) and a linear equation, and determining a relative position of the robot based on the central positional coordinate and the linear equation.
