Abstract

The invention discloses a method for determining the walking position of an intelligent lawn mower based on information fusion, which belongs to the field of robot technology. Integrate to get the distance and Hall sensor conversion to get the distance, the two data distances are fused with each other to get the driving distance information of the lawnmower; step 2, the measurement data of the accelerometer, gyroscope and Hall sensor are multi-signal and multi-level fusion, and the obtained Real-time rotation angle information of the lawn mower; step 3, determine the position of the lawn mower relative to the original coordinate point based on the walking distance and the rotation angle of the lawn mower each time. The invention makes it possible for the lawnmower to precisely delimit the working area and walk exactly according to the planned path without external electronic fence and 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...
