Multi-Lawn Mowing Path Planning With Corridor Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mowers face challenges in continuously mowing multiple lawns without manual intervention, necessitating the construction of a suitable path to facilitate seamless operation across multiple areas.
Innovation Solution
A method is provided to construct a joint mowing path for multiple lawns by displaying area maps, receiving user-defined positions, controlling the mower to travel between these positions to create a corridor path, and constructing a joint mowing path based on existing and corridor paths, enabling continuous mowing without manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a mower is used to mow multiple lawns, then the mowing coverage is improved, but the complexity of path construction and control increases
Solution Approach 1:
The system segments the multiple lawns into individual area maps, each with its own mowing path. The overall mowing task is divided into separate sub-tasks for each lawn, allowing the mower to handle each area independently while maintaining overall coordination through the joint mowing path construction.
Solution Approach 2:
A corridor path is introduced as an intermediary element connecting the different lawn areas. This corridor serves as a transition zone that allows the mower to move between separate lawns without requiring complex direct path planning between all possible lawn pairs, simplifying the overall path construction.
2Productivity
If the mower automatically mows multiple lawns continuously, then productivity is improved, but the difficulty of path planning increases
Solution Approach 1:
The system performs preliminary path planning by constructing area maps and determining mowing paths for each lawn before actual mowing begins. The corridor paths between lawns are pre-calculated, allowing the mower to execute the mowing task automatically without real-time decision-making complexity.
Solution Approach 2:
The path planning problem is transformed from a complex multi-lawn coordination problem into a series of simpler two-dimensional path planning problems. Each lawn is treated as a separate 2D area with its own mowing path, and the corridor connections provide the dimensional link between these 2D planes.
3Adaptability or versatility
If the mower travels between multiple lawns, then the versatility of the mowing system is improved, but the time required for path construction increases
Solution Approach 1:
The corridor path serves multiple functions: it connects different lawns, provides a transition zone for the mower, and can be reused for multiple lawn combinations. This universal connecting structure reduces the need to create unique paths for each lawn pair, thereby reducing overall path construction time.

AI summary
Disclosed are a method for constructing a mowing path for multiple lawns, an electronic device, and a computer readable medium. The method includes: displaying an area map of a first lawn and an area map of a second lawn; receiving a first position and a second position, wherein the first position is a position within the area map of the first lawn, and the second position is a position within the area map of the second lawn; controlling a mower to travel from the first position to the second position to obtain a corridor path; and constructing a joint mowing path for the first lawn and the second lawn based on the corridor path, a mowing path of the first lawn, and a mowing path of the second lawn. No user intervention is required while the mower operates along the joint mowing path, thereby saving manpower and facilitating.
