Robotic Mower Path Map Selection to Prevent Lawn Ruts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robotic mowers using optimized paths repeatedly crush lawns or vegetation, leading to inefficiencies and damage, as they follow the same path every time, which results in low mowing efficiency and inability to estimate completion time.
Innovation Solution
A control method and system for robotic mowers that pre-plan multiple path maps based on different moving angles and widths within the working area, allowing the mower to select a new path each time, minimizing turns and avoiding repeated paths, with features like power and weather condition monitoring to adjust operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robotic mower follows an optimized path every time, then the mowing efficiency is improved, but the lawn is repeatedly crushed and damaged
Solution Approach 1:
The system dynamically selects different path maps from a pre-planned set based on current working conditions. Instead of following a fixed optimized path every time, the robotic mower varies its path selection to balance efficiency with lawn protection, adapting the routing strategy to prevent repeated crushing of the same areas.
Solution Approach 2:
The system changes the path parameters by selecting from multiple pre-planned path maps with different routing configurations. Each path map represents a different parameter set of the mowing route, allowing the system to switch between them to avoid repeatedly traversing the same paths while maintaining coverage efficiency.
2Adaptability or versatility
If the robotic mower uses random cutting method, then the entire area is covered without knowing position, but the mowing time is extended to several days
Solution Approach 1:
The system performs preliminary action by pre-planning multiple path maps before actual mowing operations. These path maps are prepared in advance with different routing strategies, allowing the robotic mower to quickly select an appropriate path without needing to perform complex real-time pathfinding, thus reducing mowing time while maintaining coverage completeness.

AI summary
The disclosure provides a robotic mower and a control method, a system and a storage medium thereof. The control method includes: controlling the robotic mower to move to a starting point; selecting a path map from a pre-stored path map set; and controlling the robotic mower to move and work according to the selected path map. The path map set is a path map pre-planned according to different moving angles according to a working area of the robotic mower. With the disclosure, it may ensure that the robotic mower walks along different paths each time it works, thereby avoiding ruts caused by repeated rolling of the working area.
