Problems solved by technology

Among them, the infrared automatic obstacle avoidance is detected based on the triangular principle, and its disadvantages are as follows: the minimum detection distance is too large; the distance cannot be detected for objects similar to black bodies
The principle of ultrasonic wave sensor detection distance is to emit ultrasonic waves and then detect the emitted ultrasonic waves, and at the same time calculate the distance of the object according to the speed of sound. According to the principle, the disadvantages are as follows: the speed of sound is disturbed by temperature and wind direction, and may be given by the sound-absorbing surface. Absorption; the measurement distance is generally farther than infrared, and the shortest measurement distance is smaller
Based on the deficiencies of the existing technology, it is impossible to make the robot have the function of avoiding obstacles as accurately and quickly as human beings

Abstract

The invention discloses an autonomous navigation and obstacle avoidance system for a robot is disclosed. The autonomous navigation and obstacle avoidance system for the robot comprises a collecting device and a processing device, wherein the collecting device is used for collecting current nearby environment images of the robot according to an obtained voice command, and the processing device is used for subjecting the current nearby environment images of the robot to obstacle avoidance operation on the basis of a second order differential operator and a fuzzy reasoning algorithm so as to obtain obstacle information. The invention also discloses an autonomous navigation and obstacle avoidance method for the robot. By adopting a technical solution of the autonomous navigation and obstacle avoidance system and method for robot, intelligence of the robot can be improved, and the robot can autonomously avoid obstacles without human guidance.

Description

technical field [0001] The invention belongs to the technical field of robot navigation, and in particular relates to a robot autonomous navigation obstacle avoidance system and a method thereof. Background technique [0002] At present, most of the obstacle avoidance functions of robot navigation systems are realized based on infrared and ultrasonic technologies. Among them, infrared automatic obstacle avoidance is detected based on the triangular principle, and its disadvantages are as follows: the minimum detection distance is too large; the distance cannot be detected for objects that are similar to black bodies. The principle of ultrasonic wave sensor detection distance is to emit ultrasonic waves and then detect the emitted ultrasonic waves, and at the same time calculate the distance of the object according to the speed of sound. According to the principle, the disadvantages are as follows: the speed of sound is disturbed by temperature and wind direction, and may be ...
