Method and system for Open-type automation navigation based on robot

Abstract

The present invention discloses a method and system for Open-type automation navigation based on a robot. According to the user requirements, navigation scenes are determined as general navigation areas, accurate navigation areas and main path areas, the main path areas employ the Dijkstra algorithm based on a path network to obtain a path between the endpoint of the nearest path from the current position of the robot and the endpoint of the nearest path from the endpoint of a destination; and the human intervention of path planning is realized through the endpoints of the paths so as to allow the navigation to be accurate and controllable and allow the efficiency to be higher. The automatic navigation and accurate line patrol location of the robot are combined, and a buffer zone is employed to realize the transition from the general navigation areas or the main path areas to the accurate navigation areas. The width of a buffer strip is gradually reduced to 0.5-1 com from 5-10cm, the length of the buffer strip is between 20cm-100cm, and the location modes with different precisions are effectively connected to realize applicability transition of the location precision and realize smooth navigation effect.

Description

technical field [0001] The invention relates to the technical field of automatic navigation systems, in particular to a robot-based open automatic navigation method and system. Background technique [0002] At present, for the scenes of hospitals, supermarkets and logistics services, navigation robots are generally used to complete the transportation process of goods. The navigation method of the traditional navigation system adopts infrared, laser or CCD line inspection method, and the robot runs precisely along the specified planned route with the error at the millimeter level. However, the path in the line patrol navigation is a fixed path. For some occasions that require obstacle avoidance and autonomous path planning, the line patrol navigation method cannot achieve autonomous path planning, and its use has limitations. In addition, because it is based on line patrol navigation, in In the case of a large space, all stickers need to be pasted, which consumes a lot of ma...

AI Technical Summary

Problems solved by technology

The automatic navigation method using positioning and the shortest path planning algorithm has uncertainty in path planning during the path planning process. For scenes with narrow lanes formed by shelves, or scenes with a large flow of people and a large corner of the robot, if the robot makes the path Planning In the above scenario, the movement of the robot will be blocked for a long time and the speed will be slow; in addition, in some local areas of specific environments, high-precision navigation of the robot is required

Therefore, the automatic navigation method of positioning and shortest path planning algorithm cannot be applied to some scenarios with specific needs.
