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.

The present disclosure relates to a bus exception handling method of a robot including a main controller and a plurality of execution nodes electronically coupled to a bus of the robot. The main controller receives status information of an execution node of the robot from the execution node, determines whether the execution node is in an abnormal status based on the status information of the execution node. In response to determining the execution node is in the abnormal status, the main controller determines a degree of abnormity of the execution node, determines an operating instruction corresponding to the degree of abnormity, and sends the operating instruction to the execution node, the execution node executing the operating instruction. The present disclosure further provides a bus exception handling device.
