Abstract

The invention discloses a method for determining the walking position of an intelligent lawn mower based on information fusion, and belongs to the technical field of robots. The method comprises the following steps: I, arranging an accelerometer and a gyroscope in a lawn mower, arranging a Hall sensor in a motor, integrating with the accelerometer to obtain a distance, performing conversion with the Hall sensor to obtain a distance, and fusing the two data distances to obtain running distance information of the lawn mower; II, performing multi-signal multi-level fusion on measurement data of the accelerometer, the gyroscope and the Hall sensor to obtain real-time turning angle information of the lawn mower; and III, determining the position of the lawn mower relative to an original coordinate point according to the distance and turning angle of the lawn mower each time. Through adoption of the method, the lawn mower can define a working area accurately and walk accurately according toa planned path without any external electronic fence or external reference correction, thereby greatly improving the working efficiency and flexibility.

Description

technical field [0001] The invention belongs to the technical field of robots and relates to the direction of an intelligent lawn mower, in particular to a method for determining the walking position of an intelligent lawn mower based on information fusion. Background technique [0002] The smart lawn mower mainly helps people complete the mowing work, and it is a lawn mower that can realize intelligent and autonomous mowing. Intelligent lawn mowers can be separated from human control factors, thereby avoiding wasting too much human resources, saving material resources, and also have the advantages of high efficiency and high safety. Intelligent mowing means that the mowing area is artificially delineated in advance, and the mower can independently plan and walk in the artificially delineated area, traversing all positions in the area without crossing the area, so as to achieve no repetition and no omission in all directions autonomous work. This mainly includes work bound...
