Robot Cleaner Camera-Based Mapping for Precise Remote Location Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robot cleaners face challenges in precisely measuring the relative position between the user and the device, leading to difficulties in detecting the robot's location and requiring the user to be in the same area for wireless operation, which limits the convenience and accuracy of manual control.
Innovation Solution
A robot cleaner system equipped with a remote control device featuring a camera that generates image information to map the robot's location and surroundings, allowing for precise location tracking and virtual-to-actual region mapping, enabling intuitive and precise control through touch inputs and wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the robot cleaner uses conventional location detection methods, then the device structure remains simple, but the measurement precision of relative position between user and robot is insufficient
Solution Approach 1:
The patent introduces a recognition device as an intermediary element that the camera can detect. This recognition device serves as a mediator between the camera system and the robot cleaner, enabling precise location detection without requiring complex direct measurement systems. The camera captures images of the recognition device to determine the robot's position and orientation relative to the user.
2Ease of operation
If the user must be in the same area as the robot for wireless operation, then the control system remains simple, but the ease of operation is reduced
Solution Approach 1:
The patent replaces the mechanical requirement of physical proximity with an optical detection system. Instead of requiring the user to be physically near the robot for control, the camera-based system detects the robot's location through visual recognition of the recognition device, substituting mechanical presence with optical field detection.
3Productivity
If the robot cleaner lacks region mapping capability, then the device structure remains simple, but the productivity of cleaning operations is reduced
Solution Approach 1:
The patent implements preliminary mapping of the cleaning region before the actual cleaning operation begins. The camera captures and stores spatial information about the environment, creating a digital map that guides the robot's cleaning path. This preliminary action of mapping enables more efficient cleaning operations by providing advance knowledge of the workspace layout.

AI summary
A robot cleaner system may include a robot cleaner that may be automatically driven while performing a cleaning operation, a recharging base that receives the robot cleaner, and a remote control device that remotely controls the robot cleaner. The remote control device may also generate mapping information between an actual region and a virtual region based on image information generated by a camera provided on the robot cleaner, and/or image information generated by a camera on the recharging base.
