Abstract: The present disclosure provides a robot recharge docking method. The method includes: obtaining current radar data of a radar of a robot for a scanned obstacle; obtaining a position of a target object by analyzing the current radar data; controlling the robot to move to a predetermined position around the target object; determining whether infrared carrier data is received by the robot recharge docking apparatus from the target object; determining that the target object is a charging station upon receiving the infrared carrier data from the target object; and docking the robot at the target object to charge if the target object is the charging station. In the above-mentioned manner, the present disclosure can prevent the robot from taking an obstacle similar to a charging station in shape as the charging station to dock at, thereby ensuring the safety of the automatic recharging of the robot.

Abstract: The present disclosure provides a robot distance measuring method and apparatus as well as a robot using the same. The method includes: obtaining a plurality of relative position parameters of a robot from a plurality of ranging sensors; determining an installation distance between each two of the ranging sensors based on the plurality of relative position parameters; determining a sum of the installation distance of each looping arrangement of the plurality of ranging sensors based on the installation distance between each two of the ranging sensors; and enabling the plurality of ranging sensors sequentially to perform obstacle ranging according to a preset looping rule. Since the adjacent ranging sensors are avoided to range simultaneously or sequentially, the interference of the adjacent ranging sensors can be minimized, the accuracy of measuring the distance of the surrounding obstacles can be improved, thereby improving the navigation performance of the robot.

Abstract: A robotic motion control method provided by the present disclosure includes: obtaining a position and orientation of a starting point where the robot is currently located through a positioning sensor, and obtaining a position and orientation of a preset target point where the robot is moved to; determining an arc path and a straight path of the robot according to the position and orientation of the starting point, the position and orientation of the preset target point, and a preset arc radius; and moving the robot to the preset target point according to the determined arc path and straight path. Because there are only pure circular motion and pure linear motion which are simple during the movement of the robot, it is beneficial to improve the precision of the motion control of the robot and enable the robot to reach the target position in a reliable manner.
