Cleaning Robot Real-Time Area Identification to Reduce Mapping Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning robots require moving through the entire indoor space to generate a map and set a cleaning area, leading to delayed cleaning operations.
Innovation Solution
A cleaning robot that identifies entrances between areas while moving, sets a cleaning area based on its position and driving record, and cleans the area efficiently by moving along the outer edges of obstacles and using sensors like image acquirers and radar sensors to determine the entrance and set the cleaning area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the cleaning robot moves through the whole indoor cleaning space to generate a map, then the cleaning area can be accurately identified, but the cleaning time is delayed
Solution Approach 1:
The cleaning robot performs preliminary actions by moving along wall surfaces and identifying entrances before completing a full map of the entire cleaning space. This allows the robot to set and clean specific areas in real-time based on partial information gathered during movement, rather than waiting to complete the entire mapping process first.
2Measurement precision
If the cleaning robot moves along the outer edge of obstacles to identify entrances, then the entrance detection accuracy is improved, but the movement time increases
Solution Approach 1:
The cleaning robot applies local quality by concentrating its detection efforts on specific locations where entrances are likely to be found, such as along wall surfaces and at convex corners of obstacles. Rather than uniformly scanning the entire environment, the robot focuses its attention on these high-probability areas, improving entrance detection efficiency while reducing overall movement time.
3Productivity
If the cleaning robot sets the cleaning area based on real-time position and driving record, then the cleaning efficiency is improved, but the device complexity increases
Solution Approach 1:
The cleaning robot performs self-service by autonomously identifying entrances, determining cleaning areas, and executing cleaning operations without requiring complex external control systems or pre-programmed maps of the entire space. The robot uses its own movement data and sensor information to make real-time decisions about where to clean, reducing the need for sophisticated centralized control while maintaining high cleaning efficiency.

AI summary
A cleaning robot may include a main body, a driver configured to move the main body, a cleaner configured to clean a cleaning space, and a controller configured to set at least one area among a plurality of areas included in the cleaning space as a cleaning area while the main body moves, and clean the cleaning area when the cleaning area is set.
