Outdoor multimedia full-automatic floor sweeping robot

Abstract

The invention discloses an outdoor multimedia full-automatic floor sweeping robot, including an outdoor navigation system, a cleaning system and a multimedia system. the outdoor navigation system, thecleaning system and the multimedia system are controlled by the master controller, the outdoor navigation system includes a drop prevention sensor, Video and Sound Monitoring Module, RTK GNSS receivemodule, Wireless communication modules and lidar, drop sensor, video and sound monitoring module, The RTK GNSS receiving module, the wireless communication module and the laser radar are all connected on the master controller. The invention realizes the geographic position coordinates of the cleaning robot point through the independently developed RTK and the laser radar data fusion algorithm andcomplementary filtering, and accurately constructs the precise three-dimensional scene map, which has stronger robustness.

Description

Technical field [0001] The invention relates to a sweeping robot, in particular to an outdoor multimedia automatic sweeping robot. Background technique [0002] China has entered an aging society. The labor gap is slowly emerging, and the labor gap in municipal sanitation units has become increasingly obvious. At present, the need to use artificial intelligence-based robots to replace simple labor is increasingly prominent. [0003] Most of the existing traditional slam solutions have no way to adapt to complex outdoor environments, with narrow adaptability and low reliability. [0004] Currently, there is no good robot cleaning solution in the complex outdoor environment. [0005] Common methods: [0006] Use a set of single-line lidar to achieve slam navigation, build a map of the local scene, and obtain the relative position coordinates (non-earth GPS coordinates) of the positioning points. It moves back and forth in the scene and cleans with the sweeping side brush and roller st...

AI Technical Summary

Problems solved by technology

[0008] 1. Poor adaptability: the scene changes, if there are cars parked and people stop, the navigation system will fail

[0009] 2. The requirements for the flatness of the ground are extremely high: if there is a slope on the site, the navigation system cannot detect the original flat objects, resulting in the failure of the navigation system

[0010] 3. Unable to work in an open space or a site with repeated features: the factory site is empty and there are no markers, or a large number of repeated markers will fail to locate

[0011] 4. No media interaction attribute: unable to publicize environmental protection and public welfare content, and has no guiding and discouraging effect on citizens
