Boundary Working Map for Adaptive Robotic Lawn Mowing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic lawn mowers often fail to clean grass in parts of the boundary area due to a single working mode, leading to inefficiencies and the need for reworking.
Innovation Solution
Generate a working map by recording position information of path points and determining boundary attributes, allowing for different working modes based on these attributes to improve efficiency and accuracy in mowing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single preset working mode is used for boundary mowing, then the device complexity is reduced, but the manufacturing precision of boundary grass cutting deteriorates
Solution Approach 1:
The patent applies local quality by assigning different working modes to different boundary segments based on their specific characteristics. The boundary is divided into multiple segments, and each segment is assigned a working mode (first, second, or third) according to its local features such as grass height, boundary type, or terrain conditions. This allows the system to maintain simple overall control while achieving high precision in boundary grass cutting through localized mode selection.
2Ease of operation
If a single working mode is used for all boundary areas, then the ease of operation is improved, but the productivity deteriorates due to reworking
Solution Approach 1:
The patent implements dynamics by making the working mode adaptive and changeable based on real-time boundary conditions. The system dynamically selects from multiple working modes (first, second, third modes) depending on the specific segment being mowed, rather than using a fixed single mode. This dynamic adaptation eliminates the need for reworking while maintaining operational simplicity through automated mode selection based on pre-configured boundary segment characteristics.
3Manufacturing precision
If multiple working modes are implemented for different boundary points, then the manufacturing precision of boundary grass cutting is improved, but the device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring the boundary into multiple segments and assigning appropriate working modes to each segment before the mowing operation begins. The boundary attribute configuration information is established in advance, storing the correspondence between boundary segments and their designated working modes. During actual operation, the system simply retrieves and executes the pre-determined mode for each segment, achieving high precision without increasing operational complexity.
Solution Approach 2:
The patent introduces an intermediary layer in the form of boundary attribute configuration information that mediates between the complex multiple working modes and the simple operational execution. This configuration layer stores the mapping between boundary segments and their corresponding working modes, acting as a pre-computed lookup table that simplifies real-time decision-making during mowing operations while enabling precise mode selection for each boundary segment.

AI summary
A method for generating a working map, an operation method, a control method, and a related apparatus are provided. The method includes the following operations. The automatic operation apparatus is controlled to move, to record position information of multiple path points on a movement path of the automatic operation apparatus. Boundary attribute configuration information is received, and boundary attributes of at least a part of the path points are determined according to the boundary attribute configuration information. A working map including position information of multiple boundary points and boundary attributes of at least a part of the boundary points is generated. Multiple boundary points are configured to indicate a virtual boundary surrounding a preset area, and when the automatic operation apparatus performs operations along the virtual boundary, working modes when the automatic operation apparatus moves to boundary points corresponding to different boundary attributes are different.
