Robot Cleaner Multi-Sensor Detection to Prevent Valuable Article Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot cleaners often fail to recognize and avoid small articles or valuables while cleaning, leading to potential loss as they operate on predetermined paths without adequate obstacle detection.
Innovation Solution
An intelligent robot cleaner equipped with a sensing unit that includes image, weight, and sound sensors to identify and analyze articles collected during cleaning, using AI learning to differentiate between foreign matter and valuables, and notify the user through a communication unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the robot cleaner operates on a predetermined travel path without advanced sensing, then the device complexity is low and ease of operation is high, but the reliability of cleaning is poor because small articles or valuables cannot be identified and may be sucked
Solution Approach 1:
The robot cleaner performs preliminary sensing of the cleaning area before actual cleaning to identify articles and valuables in advance. The sensing unit captures images of the cleaning path, and the control unit analyzes these images to detect articles before the suction operation begins, allowing the robot to adjust its path or avoid sucking valuable items
Solution Approach 2:
The patent introduces an intermediary analysis process between the sensing unit and the suction unit. The control unit acts as an intermediary that receives sensor data, processes images to identify articles, and then makes decisions about whether to proceed with suction or adjust the travel path, thereby preventing valuable items from being sucked
2Measurement precision
If the robot cleaner uses simple obstacle detection, then the device complexity is low, but the measurement precision is insufficient to distinguish between small articles/valuables and ordinary foreign matter
Solution Approach 1:
The patent transitions from simple 2D obstacle detection to multi-dimensional analysis by capturing images with the sensing unit and analyzing them in the control unit. This dimensional change from basic proximity sensing to image-based recognition enables precise identification of articles and valuables, distinguishing them from ordinary dust and foreign matter through visual characteristics
Data Source
AI summary
Disclosed herein is an intelligent robot cleaner. The intelligent robot cleaner primarily senses foreign matter sucked through a suction unit under the control of a control unit, and secondarily senses an article collected in a collection unit, if articles other than the foreign matter are sensed, thus allowing a use to recognize accurate information about the article collected in the collection unit and preventing valuables or small articles from being lost. The intelligent robot device may be associated with an artificial intelligence module, a unmanned aerial vehicle (UAV), a robot, an augmented reality (AR) device, a virtual reality (VR) device, devices related to 5G services, and the like.
