Abstract: A computer-implemented method for localizing a robot comprising an ultra wideband (UWB) localization device, at least one sensor and a particle filter localization device. The method comprising executing on a processor steps of: acquiring first location information of the robot through the UWB localization device; acquiring second location information within a range defined by the first location information through the at least one sensor, wherein the second location information comprising current location information and running orientation data of the robot; and determining, by the particle filter localization device, whether there exists a localization point matching the second location information in data of a preset map; if so, determining that the second location information is valid location information of the robot.

Abstract: The present disclosure relates to a motion-controlling method of a robot and the robot thereof. A main control circuit continuously transmits a controlling instruction to a cache circuit. The controlling instruction may include the controlling information of a specific servo. A driving circuit is configured to obtain and analyze the controlling instruction from the cache circuit, so as to obtain the controlling information of the specific servo. The driving circuit transmits the controlling information to the specific servo to control the specific servo. As such, coherence of the robot may be improved.

Abstract: The present disclosure discloses a robot recharge control method, a robot and a robot system. The robot recharge control method includes: moving a robot to a first position of one of two edge lines of a preset detection signal region; moving the robot from the first position to a second position of the other edge line of the preset detection signal region; moving the robot from the second position to a midpoint of a line connecting the first position and the second position; and moving the robot from the midpoint to the dock section of the charging base. By detecting the two edge lines of the preset detection signal region, the first position and the second position which are axisymmetric with respect to the dock section are found, and then a center point corresponding to the dock section is found through the first position and the second position.
