Embodiment Construction

[0016] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0017] In the embodiment of the present invention, one laser sensor is set, combined with the method of short-term memory, the obstacle distribution of the scene around the AGV is collected in real time through the laser sensor, and the obstacle avoidance algorithm is designed according to the collected obstacle distribution, and the obstacle avoidance strategy is formulated to control AGV independently finds feasible channels, bypasses obstacles, reaches the target location, and realizes autonomous obstacle avoidance.

[0018] The laser sensor can emit laser beams to obtain the distribution information of surrounding obstacles. Take the fan-shaped area 180° in front of the laser sensor with a radius of 5m as the detection range, such as figure 1 shown. Since the fan-shaped area has a large amount of calculation when d...

Abstract

The invention discloses an autonomous obstacle avoidance method for AGV and relates to an AGV. A laser sensor is provided. In combination with a short-term memory method, the obstacle distribution around the AGV is acquired by the laser sensor in real time. According to the acquired obstacle distribution, an obstacle avoidance algorithm is designed and an obstacle avoidance strategy is established, and the AGV is controlled to search out a feasible channel, bypassing the obstacles to reach a target location, thereby achieving autonomous obstacle avoidance. In a complicated environment, the AGVcan automatically avoid obstacles for unobstructed driving, reduces the possibility of accidents, selects the optimal channel, and greatly improves the working efficiency.

Description

technical field [0001] The invention relates to an AGV, in particular to a method for autonomous obstacle avoidance of the AGV. Background technique [0002] The first AGV was born in 1953. AGV has been used as a logistics intelligent robot for more than 60 years, and the application of AGV is becoming more and more extensive. AGV is equipped with automatic guidance devices such as electromagnetic or optical. It can drive along the specified guiding path, which greatly meets the automation needs of handling production, reduces labor costs, and improves production efficiency. However, during the operation of the car, there may be obstacles in front of the car that affect the driving or even cause a collision. Therefore, providing a method that can automatically avoid obstacles can improve production efficiency and reduce the time of staying due to obstacles. . [0003] Chinese patent CN106774313A discloses a multi-sensor based outdoor automatic obstacle avoidance AGV naviga...
