Virtual Boundary Closure for Autonomous Lawn Mowers

The autonomous mobile mowing apparatus automatically detects loop closure and performs boundary closure operations without requiring continuous manual guidance. The system uses its own sensor data and positioning information to autonomously determine when the boundary is closed and executes the closure process, making the system self-sufficient and reducing user intervention requirements.

The system continuously monitors its positioning data and compares the current position with the starting position to detect loop closure. This feedback mechanism allows the apparatus to automatically recognize when the boundary closure condition is met and triggers the appropriate response, eliminating the need for constant manual oversight and improving closure efficiency.

The system performs preliminary detection of loop closure conditions by continuously monitoring positioning data before executing boundary closure. By anticipating the closure condition in advance and preparing the appropriate response, the system avoids unnecessary repeated adjustments and prevents lawn damage that would result from multiple roll-over operations.

The patent replaces manual mechanical guidance and repeated physical adjustments with an automated electronic control system that uses sensor feedback and algorithmic decision-making. This substitution eliminates the need for repeated mechanical adjustments that cause lawn damage while maintaining high boundary closure accuracy.
