Wire-Based Region Division for Accurate Mowing Robot Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mowing robots experience low positioning accuracy due to the division of preset regions into sub-regions that may not contain the wire, leading to inadequate posture correction during operations.
Innovation Solution
A region division method that divides the preset region into sub-regions containing a respective section of the wire, allowing the robot to perform posture correction and improve positioning accuracy by moving along the wire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the preset region is divided into mesh-like sub-regions of equal size, then the region segmentation is simple and uniform, but the positioning accuracy of the robot decreases because sub-regions may not contain the wire for posture correction
Solution Approach 1:
The preset region is divided into multiple sub-regions, but unlike conventional mesh-like division, each sub-region is specifically designed to contain at least one section of the wire. This segmentation approach maintains the benefits of region division while ensuring that each sub-region provides positioning reference through the wire, thereby resolving the contradiction between segmentation simplicity and positioning accuracy.
Solution Approach 2:
Instead of uniform mesh-like division, the patent applies non-uniform division where each sub-region has the specific quality of containing a wire section. This local quality ensures that every sub-region provides posture correction capability, directly addressing the positioning accuracy issue while maintaining region segmentation benefits.
2Measurement precision
If the robot relies on the wire for posture correction, then positioning accuracy is maintained in regions with wire, but sub-regions without wire suffer from low positioning accuracy
Solution Approach 1:
By segmenting the region such that each sub-region contains at least one wire section, the patent ensures that posture correction capability is distributed across all sub-regions. This eliminates the reliability issue of having wireless sub-regions while maintaining the effectiveness of wire-based positioning.
Solution Approach 2:
The wire serves multiple functions: it defines the boundary of the preset region and simultaneously provides positioning reference for each sub-region. This multi-functionality ensures that the wire benefits the entire workspace uniformly, resolving the reliability contradiction.
