Mobile robot and navigation method of mobile robot

Abstract

The invention discloses a mobile robot. The mobile robot comprises a central processing module; a distance measuring sensor, an auxiliary obstacle avoidance module, and a man-machine interaction module, which are connected with the central processing module. The distance measuring sensor is used to scan the operation space of the mobile robot to establish an environmental map. The auxiliary obstacle avoidance module is used to detect obstacles and cliff boundaries in the sensing blind area of the distance measuring sensor during the moving of the mobile robot, and then the environmental map is improved. A user can input virtual obstacle information in the environmental map by the man-machine interaction module, and then the environmental map is further improved. The moving path of the operation of the mobile robot is planned according to the environmental map. The mobile robot is used to establish and improve the environmental map of the operation space in a step-by-step manner, and the moving path is planed according to the environmental map, and therefore the obstacles are accurately avoided, time and energy are saved. The invention also discloses the navigation method of the mobile robot.

Description

technical field [0001] The invention relates to the field of smart devices, in particular to a map-based mobile robot and a navigation method for the mobile robot. Background technique [0002] At present, mobile robots are used in many fields, such as drones, cleaning robots, etc., especially household cleaning robots have been widely used in household services, reducing people's housework troubles. In the prior art, the mobile robot detects obstacles within a short distance in front of the robot by simply touching a switch or an infrared sensing device, and only adjusts the moving direction of the mobile robot when it collides with an obstacle during the movement process, and then according to The pre-set mode continues to move foolishly, and it is easy to mess up the dominant direction in the work space when encountering obstacles many times. This simple obstacle avoidance processing and path planning make the robot have no clear dominant direction when moving in the wor...

In the prior art, the mobile robot detects obstacles within a short distance in front of the robot by simply touching a switch or an infrared sensing device. During the movement, the mobile robot can only adjust the moving direction when it collides with an obstacle, and then according to The pre-set mode continues to move foolishly, and it is easy to mess up the dominant direction in the work space when encountering obstacles many times

This simple obstacle avoidance processing and path planning make the robot have no clear dominant direction when moving in the work space, eventually causing the robot to move back and forth between some positions, and even fail to reach the predetermined target position, wasting time and energy
