Abstract

The invention discloses a high-sensitivity obstacle avoidance system and method for an AGV robot. By obtaining the safe running width of the AGV robot and the shortest distance between the road base point and the obstacle model; when the shortest distance between the road base point and the obstacle model is less than the safe running width , select the N+1th road for obstacle avoidance; when the shortest distance between the road base point and the obstacle model is greater than or equal to the operating safety width, use the road base point as the driving boundary point for obstacle avoidance, and the AGV robot can accurately avoid obstacles. The current obstacle avoidance system is dynamic obstacle avoidance, and the sensor fails at one point, and the obstacle avoidance cannot be avoided; the present invention loads the pre-established three-dimensional model map into the AGV robot to avoid information delay caused by data transmission, and at the same time through the three-dimensional The positioning of the road boundary on the model map makes it possible to avoid obstacles through the coordinate points in the three-dimensional model map even when the obstacle avoidance sensor fails.

Description

technical field

[0001] The invention belongs to the field of AGV robots and relates to high-sensitivity obstacle avoidance technology, in particular to a high-sensitivity obstacle avoidance system and method for AGV robots. Background technique

[0002] AGV is: Automated Guided Vehicle, referred to as AGV. The most common application at present is: AGV handling robot or AGV trolley. The guidance methods are magnetic strip guidance, laser guidance, magnetic nail navigation and inertial navigation;

[0003] Manufacturing industry: AGV handling robots on the market are mainly used in manufacturing material handling. In manufacturing applications, AGV completes material handling tasks efficiently, accurately and flexibly. Moreover, multiple AGVs can form a flexible logistics handling system, and the handling route can be adjusted in time with the adjustment of the production process, so that more than a dozen products can be produced on one production line, which greatly improv...
