Robot Lawn Mower Interruption Control for Weather and Low Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot lawn mowers are prone to damage during unexpected situations such as bad weather or power failure due to the lack of timely user intervention, necessitating inconvenient monitoring and management.
Innovation Solution
A robot lawn mower equipped with a chassis, cutting device, sensor unit, and processor that implements a controlling method including a mowing procedure, interruption determining procedure, and interrupting procedure to stop cutting and move to a standby location when conditions such as bad weather or low power are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the robot lawn mower operates autonomously without monitoring, then automation level increases, but reliability decreases due to damage from unexpected situations
Solution Approach 1:
The robot lawn mower continuously receives sensing data from sensor units during mowing operations and uses this feedback to determine whether interruption conditions are met. The system automatically adjusts its operation based on real-time environmental and operational status information, enabling it to respond to unexpected situations without user intervention.
Solution Approach 2:
The system performs preliminary actions by pre-setting standby locations and pre-defining interruption conditions before mowing operations begin. When adverse conditions are detected, the mower has already prepared safe locations and can immediately execute protective maneuvers without requiring real-time user decisions.
2Reliability
If the robot lawn mower continuously monitors environment and operation status, then reliability improves through timely interruption, but device complexity increases
Solution Approach 1:
The monitoring system is segmented into multiple independent sensor units, each responsible for detecting specific environmental or operational parameters. The processor receives sensing data from these separate units and evaluates interruption conditions based on predefined criteria, allowing the complex monitoring task to be divided into manageable segments.
3Reliability
If the robot lawn mower stops mowing and moves to standby location upon detecting adverse conditions, then reliability improves, but productivity decreases
Solution Approach 1:
The system applies partial action by selectively interrupting mowing operations only when specific interruption conditions are met, rather than continuously stopping. The processor evaluates sensing data against predefined criteria and resumes mowing after moving to standby locations, balancing protection needs with productivity requirements.

AI summary
A controlling method of a robot lawn mower includes a mowing procedure, an interruption determining procedure and an interrupting procedure. The interruption determining procedure includes steps of receiving sensing data indicating a current sensing result related to at least one of surrounding environment or an operation status of the robot lawn mower, and determining whether an interruption condition related to at least one of an environment factor or an operation factor of the robot lawn mower is met. When it is determined that the interruption condition is met, the interrupting procedure is executed, and the robot lawn mower moves to a preset standby location.
