Problems solved by technology

[0002] The mowing paths of most lawn mowing robots currently on the market are random, which leads to a slightly messy lawn after the mower has mowed the grass. At the same time, it takes more time to mow the grass to completely traverse the working area, resulting in The efficiency is low. Although the non-intelligent lawn mower can cut a flat lawn under manual operation, it is time-consuming and laborious. Therefore, the automatic positioning technology is combined with the lawn mower to realize the directional positioning of the lawn mower, and Use the map construction technology to realize the robot's autonomous path planning, and finally cut out a smooth and regular lawn

Embodiment Construction

[0026] The technical solution of the present invention will be further described in detail below.

[0027]In the method of the present invention, the robot is mainly a mowing robot, which is a four-wheeled robot, and the rear two wheels are differential wheels, which can realize the movement of the robot in any direction. The robot is powered by a lithium battery. Work autonomously within the range. The area is artificially delineated by the boundary line, which can be of any shape and size. The boundary line is an electrified wire, and there is a specific boundary signal in the wire. The boundary signal is sent by the charging base station, and the base station can provide charging for the robot. When the power of the robot is low, it will automatically return to the base station along the boundary line to charge, and it will automatically go out of the base station to work after it is fully charged. The robot will recognize that the robot is inside the boundary line by receiv...

Abstract

The invention discloses a robot map establishing and storing method. The method comprises the steps that an electronic compass and a speedometer are used for achieving positioning and coordinate calculation of a robot combined with a GPS, before map data are established, the robot operates a circle around a working area along a boundary first, map boundary data are established, the mapping relation of the map data and the address of a storage unit is calculated, then the robot operates in the area, and then internal map data are established. The format of the map data is {X coordinate, Y coordinate and map grid attributes}, and in order to facilitate data storage, the data are mapped into storage space according to a certain rule.

Description

technical field [0001] The invention belongs to the technical field of robots and relates to a method for constructing map information. Background technique [0002] The mowing paths of most lawn mowing robots currently on the market are random, which leads to a slightly messy lawn after the mower has mowed the grass. At the same time, it takes more time to mow the grass to completely traverse the working area, resulting in The efficiency is low. Although the non-intelligent lawn mower can cut a flat lawn under manual operation, it is time-consuming and laborious. Therefore, the automatic positioning technology is combined with the lawn mower to realize the directional positioning of the lawn mower, and Using map construction technology to realize the robot's autonomous path planning, and finally cut out a smooth and regular lawn. Contents of the invention [0003] Technical problem: The present invention provides a robot map construction and storage method that realizes ...
