Autonomous Lawn Mower Rework Control From User Satisfaction Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous lawn mowing machines lack a method to instruct rework based on user satisfaction, requiring manual intervention to address unsatisfactory work results.
Innovation Solution
A working system equipped with a user state detecting unit, rework determining unit, and actuator controlling unit that autonomously determines the need for rework and controls the working and traveling actuators to perform necessary adjustments based on user satisfaction levels detected through biological information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the working machine operates autonomously without user feedback mechanisms, then automation level is improved, but the ability to perform rework based on user satisfaction deteriorates
Solution Approach 1:
The system incorporates a user state detecting unit that monitors user satisfaction levels and feeds this information back to the control unit. When the user expresses dissatisfaction with the work results, the control unit receives this feedback and automatically initiates rework operations, resolving the contradiction between autonomous operation and adaptability to user needs.
2Device complexity
If the working machine lacks user state detection capabilities, then device complexity is reduced, but the ability to detect user satisfaction and perform rework deteriorates
Solution Approach 1:
The system replaces complex mechanical or manual assessment methods with a biological information detecting unit that uses sensors to detect user states such as facial expressions, voice tone, or physiological signals. This substitution enables user satisfaction detection while maintaining relatively simple device architecture, as the detection is performed automatically through non-invasive sensing rather than complex mechanical interfaces.
3Ease of operation
If manual intervention is required to instruct rework, then ease of operation is reduced, but control precision over rework timing is improved
Solution Approach 1:
The system enables self-service operation where the working machine automatically determines when rework is needed based on user state detection. The control unit monitors user satisfaction levels and autonomously initiates rework operations without requiring manual intervention, thereby improving ease of operation while maintaining precise assessment of user satisfaction through continuous biological information monitoring.

AI summary
A working system (100) includes: a working actuator (26) installed on a working machine (1); a camera (21) and a microphone (22) detecting a state of a user changing in accordance with a satisfaction level; a rework determining unit (11) determining whether a rework is needed based on the detected state of the user after a predetermined work is performed by the working machine (1); and an actuator controlling unit (15) controlling the working actuator (26) to perform the rework when it is determined by the rework determining unit (11) that the rework is needed.
