Autonomous Mower Transfer Paths to Prevent Lawn Rut Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for generating transfer paths for autonomous mobile mowing apparatuses frequently results in obvious marks on lawns due to repetitive paths, affecting aesthetics.
Innovation Solution
A method that determines a traveling start and end point, identifies traversed regions, performs shortest path searches within these regions, and generates a random transfer path by adding randomly determined points outside the initial paths, ensuring stochastic path variation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the autonomous mobile mowing apparatus uses shortest path planning method for transfer, then the transfer efficiency is improved, but the lawn aesthetics deteriorates due to obvious marks from repetitive paths
Solution Approach 1:
The patent applies dynamics by making the transfer path variable rather than fixed. The system dynamically selects different transfer paths based on historical data, changing the path configuration over time to avoid repetitive traversal of the same route, thereby preventing lawn mark formation while maintaining efficient transfer between work regions
Solution Approach 2:
The patent changes the path selection parameter from always choosing the shortest path to selecting from multiple candidate paths with different lengths. By modifying the path selection criterion to consider path diversity rather than only minimum distance, the system avoids repetitive traversal while still maintaining acceptable transfer efficiency
2Loss of time
If the autonomous mobile mowing apparatus frequently traverses the same transfer path, then the transfer time is reduced, but the lawn surface deteriorates due to rut formation
Solution Approach 1:
The patent implements periodic action by alternating between different transfer paths in a cyclic manner. The system uses historical traversal data to periodically switch paths, ensuring that no single path is traversed repeatedly for extended periods, thus preventing rut formation while maintaining efficient transfer operations

AI summary
A method is provided. The method includes: determining a traveling start point and a traveling end point of position transfer of an autonomous mobile mowing apparatus; and determining at least one to-be-traversed region which the apparatus traverses when moving from a start point to an end point of position transfer of the apparatus. The determining operation includes: determining, in response to the start point and the end point being located in different work regions, at least one work region sequence according to a connection relationship between at least three work regions. The work region sequence includes at least three sequentially connected work regions; randomly determining a target work region sequence from the at least one work region sequence; and determining the at least three work regions included in the target work region sequence respectively as the to-be-traversed regions.
