Solution Overview
Problem
Existing cleaning robots face inefficiencies in wet cleaning due to insufficient friction with the floor surface, potential damage from increased friction without a cleaning cloth, and risks of water accumulation leading to accidents, with the absence of the cleaning cloth often undetected.
Innovation Solution
A moving robot equipped with a spin mop system that includes first and second rotary plates with cleaning cloths, a controller to detect the presence or absence of the cloths, and a method to analyze location changes to prevent operation when cloths are not attached, thereby increasing friction for effective cleaning and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the robot operates with increased friction for cleaning efficiency, then cleaning performance is improved, but damage to the robot and floor surface occurs
Solution Approach 1:
The system performs preliminary detection of cleaning cloth presence before initiating cleaning operations. The controller checks whether the cleaning cloth is properly attached to the rotary plate, and only allows operation when the cloth is confirmed present, thereby preventing damage before it occurs
Solution Approach 2:
The system implements feedback control by continuously monitoring the presence of the cleaning cloth during operation. When the cloth is detected to be missing or improperly attached, the controller automatically stops the rotary plate rotation, creating a closed-loop control system that prevents damage while maintaining cleaning efficiency when properly configured
2Productivity
If water is supplied during operation, then cleaning effectiveness is improved, but water accumulates on the floor causing safety accidents
Solution Approach 1:
The system performs preliminary verification of cleaning cloth attachment before enabling water supply. The controller checks the presence detection signal and only activates the water supply function when the cleaning cloth is confirmed to be properly attached, preventing water accumulation hazards before they can occur
Solution Approach 2:
The system implements feedback control by continuously monitoring cleaning cloth presence during water supply operations. When the cloth is detected to be missing, the controller automatically stops water supply, creating a safety mechanism that prevents water accumulation while maintaining cleaning effectiveness when properly configured
3Ease of operation
If the cleaning cloth is attached at the bottom of the robot, then cleaning function is provided, but user cannot recognize absence of the cloth
Solution Approach 1:
The system implements feedback to the user by providing visual or audible notifications when the cleaning cloth is detected to be missing or improperly attached. This allows users to immediately recognize the problem and take corrective action, maintaining ease of operation while eliminating information loss
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system ensures efficient wet cleaning by maintaining sufficient friction, prevents damage to the robot and floor, and avoids water accumulation, allowing users to promptly recognize cloth absence and stop operations to maintain safety.
Implementation Method 1
a moving robot and a control method thereof for operating a main body while rotating a cleaning cloth by means of a motor, thereby performing wet cleaning on a floor surface with an increased friction

AI summary
Provided are a moving robot and a control method thereof. The mocking robot is configured to rotate a cleaning cloth by means of a motor to move a main body and clean a floor surface. A location change of the main body is analyzed to determine a traveling state, an operation is controlled and a warning is output by detecting the absence of the cleaning cloth according to the traveling state. A notification regarding whether the cleaning cloth is installed is output to allow a user to recognize the same. An operation of the main body is stopped to prevent damages to a product and the floor surface and prevent an accident.
