Problems solved by technology

[0002] When a robot executes a task, the management background usually sends the task to the robot according to the order situation, including the target site, the predetermined path, etc., and the robot executes the task according to the preset path after receiving the task. Adjust the path. When the robot is walking, if it encounters a road section with complex flow of people and many obstacles, it will cause the robot to walk slowly or even stagnate. When the road condition information is adjusted, it is very likely to walk to the congested road section, which will cause the road section to become more and more congested. At this time, the task will be time-consuming and affect the working efficiency of the robot.

Embodiment Construction

[0041] A robot path planning and scheduling method, such as figure 1 , including the following steps:

[0042] 1. Setting of road section and reference speed

[0043] Pre-scan the environment with the laser radar of the robot to obtain the environmental map and establish a coordinate system, set the site in the map according to the business type, form a road section between two adjacent sites, and connect all the road sections between the two sites in turn to form a path between the two sites; And the reference speed of each road section is preset according to the channel width of each road section pre-scanned. A station is a business-related location point, or a complex route is divided into several simplified road sections according to road conditions. According to the plan, there may be multiple paths composed of different road sections between two stations.

[0044] The reference speed of each road section is set according to the passage width of each section. When the p...

Abstract

A robot path planning and dispatching method, comprising the steps of: pre-scanning the environment through the laser radar of the robot to obtain an environmental map and establish a coordinate system, preset the reference speed of each road section according to the channel width; Compare the speed with the reference speed of the road section to generate a dynamic speed map; generate a statistical speed map based on the historical average speed of each road section; filter the target robot according to the task order, and plan the path according to the dynamic speed map and the statistical speed map; it can also be based on real-time road conditions Schedule the planned path. The invention plans the path of the robot according to the real-time dynamic speed and the historical statistical speed, so that the path planning is more scientific and reasonable, and adjusts the operation route in real time according to the real-time dynamic speed data, so as to ensure the shortest time and optimize the operating efficiency of the robot. The map is corrected to make the reference data more scientific.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a robot path planning and dispatching method. Background technique [0002] When a robot executes a task, the management background usually sends the task to the robot according to the order situation, including the target site, the predetermined path, etc., and the robot executes the task according to the preset path after receiving the task. Adjust the path. When the robot is walking, if it encounters a road section with complex flow of people and many obstacles, it will cause the robot to walk slowly or even stagnate. When adjusting the road condition information, it is very likely that the robot will also walk to the congested road section, which will cause the road section to become more and more congested. At this time, the task will be time-consuming and affect the working efficiency of the robot. Contents of the invention [0003] The purpose of the present invention is...
