Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as figure 1 As shown, an intelligent security service robot complex environment obstacle avoidance method of the present invention is an organic fusion of multiple obstacle avoidance methods; it includes:

[0034] S1: Laser obstacle avoidance; after the offline map is established, use laser radar to detect obstacles within the effective range and the distance between the robot and obstacles in real time, mark them as coordinates on the map, and bypass these obstacles in path planning;

[0035] S2: Ultrasonic obstacle avoidance; in the case that no obstacle is detected by the laser radar method, rely on the ultrasonic sensing method to assist in detecting obstacles and distance information, and realize obstacle avoidance;

[0036] S3: Infrared obstacle avoidance; if the infrared sensor 9 detects that the distance between t...

Abstract

The invention discloses an intelligent security service robot complex environment obstacle avoidance method and a security service robot. The method includes: S1: laser obstacle avoidance; The distance between the robot body and obstacles is marked as the coordinates on the map; S2: Ultrasonic obstacle avoidance; in the case that no obstacle is detected by the laser radar method, rely on the ultrasonic sensing method to assist in detecting obstacles and distance information, and realize obstacle avoidance ;S3: Infrared obstacle avoidance; if the infrared sensor detects that the distance between the chassis and the ground exceeds the preset threshold during the robot’s movement, it will avoid obstacles; S4: Collision obstacle avoidance; way to avoid obstacles. The above-mentioned obstacle avoidance method is implemented on the robot. The invention has the advantages of good controllability, more flexible movement, stable and reliable system performance, high obstacle avoidance precision and the like.

Description

technical field [0001] The invention mainly relates to the field of intelligent robots, in particular to an intelligent security service robot complex environment obstacle avoidance method and a security service robot. Background technique [0002] Intelligent robot is a comprehensive system integrating autonomous navigation, environmental perception and local construction, dynamic decision-making and planning, autonomous control and execution, etc. It represents the highest achievement of mechatronics and is also one of the hot spots in scientific research and engineering design today. one. [0003] One of the functions necessary for the robot's autonomous navigation is self-positioning, which requires knowing its position, direction, and destination at any time. Efficient to avoid and finally reach the finish line. [0004] More and more robots appear in various engineering fields, which brings great convenience to industrial production and engineering applications. Howe...
