Wet Floor Cleaning Robot Routing to Avoid Wheel Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robots often leave traces on wet or damp sections of the floor due to their inability to accurately determine and avoid these areas during operation.
Innovation Solution
A method for controlling a cleaning robot that involves determining the moisture level of a floor section based on past cleaning data and only accessing sections with a moisture level below a predetermined threshold, ensuring that the robot plans its route to avoid wet sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cleaning robot re-drives over already cleaned areas to ensure complete coverage, then cleaning completeness is improved, but visible wheel marks are left on the cleaned surface
Solution Approach 1:
The robot determines the moisture level of floor sections before traveling over them using sensors. By checking the moisture level in advance, the robot can plan its route to avoid wet sections, preventing wheel marks from being left on the cleaned surface while still ensuring complete coverage of dry areas.
2Manufacturing precision
If the robot uses sensors to detect moisture level and avoid wet sections, then the quality of cleaned surface is improved, but the device complexity increases
Solution Approach 1:
The patent replaces complex mechanical solutions with sensor-based detection and electronic control. Instead of using complex mechanical mechanisms to avoid wet areas, the robot uses moisture sensors and a control unit to detect and navigate around wet sections, simplifying the overall system while improving cleaning quality.
3Speed
If the robot travels over wet floor sections, then navigation speed is maintained, but the drive wheel grip is reduced and navigation accuracy decreases
Solution Approach 1:
The robot determines the moisture level of floor sections before traveling over them. By checking moisture levels in advance and planning its route accordingly, the robot maintains its drive wheels on dry sections, ensuring both navigation speed and accuracy are maintained throughout the cleaning process.

AI summary
A method (300) for controlling a robot (100) for wet cleaning a floor surface (105) comprises steps of driving (310) over the floor surface (105) and wet cleaning (310) a driven-over section of the floor surface (105). The moisture level of a section of the floor surface (105) to be driven over by the robot (100) is determined (330, 335); and the section is driven over only if the moisture level is below a predetermined threshold.
