Abstract

Embodiments of the invention provide a path planning method and system for a mobile robot, and belong to the field of robots. The path planning method for the mobile robot includes receiving a first planning path from a mobile robot, the first planning path being autonomously planned by the mobile robot in a predetermined area; planning a second planning path for the mobile robot; based on a pre-stored standard path segment and a static path cost value corresponding to the standard path segment, determining a first path cost value and a second path cost value respectively corresponding to thefirst planned path and the second planned path; and comparing the first path cost value and the second path cost value, and sending a corresponding control instruction to the mobile robot according toa comparison result, wherein the mobile robot can recognize the control instruction and move according to the first planned path or the second planned path. Thereby, the basis for efficient operationof the mobile robot is guaranteed, and the response efficiency of a server and the transmission efficiency of the mobile robot are improved.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a method and system for path planning of a mobile robot. Background technique [0002] Deploying multiple mobile robots in a dense area (such as a logistics warehouse area) and using these mobile robots to complete tasks such as handling goods to replace manual labor is the current research focus in the field of the Internet of Things. [0003] In order to avoid collisions between multiple mobile robots in dense areas during operation, the following two different processing schemes are generally adopted at present: First, the robots have good conflict resolution capabilities through the current local environment information of the robots ; The second is centralized management conflict resolution, which mainly eliminates conflicts by segmenting the robot's motion path. [0004] However, the inventors of the present application found that there are at least the following defects in...
