Autonomous patrolling method of robot

The invention discloses an autonomous patrolling method of a robot. The robot obtains a virtual map with the xy coordinate in reality through mapping firstly, and target points where the robot arrives are arranged on the map; the created map and target point data are uploaded to a server, and the uploaded coordinate point data are configured as a patrolling route of the robot in the server; the robot patrols autonomously within the patrolling time period and returns to an initial patrolling point after exceeding the patrolling time period; in the patrolling process, if touched or detecting the situation that a person enters the set distance range, the robot starts a voice interaction recognition mode and stops patrolling; if no voice interaction is conducted for a long time, the robot stops voice interaction, and after finishing, the robot still patrols till the end of the patrolling time. The related problems of fixed-point and fixed-time patrolling and patrolling with voice interaction of the robot can be s
