Problems solved by technology

This way of interacting with the database simplifies the logic of the simulation, but limits the scale of the simulation
For a large-scale picking library, when the number of storage locations, picking stations, and handling robots is relatively large, the location information of the handling robots is updated in the database in real time, resulting in an increase in the amount of interactive data and the frequency of interaction. The simulation model cannot run, which affects the simulation effect

Abstract

The invention discloses a robot path planning method and device, which relate to the field of computer information processing. The method comprises steps: a start point and an end point of a to-be-processed task of the robot are acquired; a robot map is initialized, wherein the robot map comprises a no load map and a full load map; the shortest path between the start point and the end point is acquired through the robot map and a shortest path algorithm; and an advancing route of the robot processing the task is determined through a back tracking algorithm. According to the robot path planningmethod and the device disclosed in the invention, the walking path of the handling robot can be directly calculated in simulation, the frequency of interactions with a database is reduced, and the simulation operation speed is improved.

Description

technical field [0001] The invention relates to the field of computer information processing, in particular to a method and device for robot path planning. Background technique [0002] With the popularization of robot technology, a large number of jobs are realized by robots, especially in the work of warehousing and logistics. In a warehouse using the goods-to-person picking model, such as figure 1 As shown, the outbound picking station is located on one side of the warehouse, and the handling robots are randomly distributed under the storage positions when they are idle. There are shelves on the storage positions. A shelf has two sides, and several kinds of commodities are stored on each side. In the outbound picking process, the handling robot is responsible for transporting the shelves to the corresponding picking stations, and the pickers start to pick the goods. After the picking is completed, the handling robot then transports the shelves to a free storage space for...
