Robot Cleaner Mapping Control for Precise Remote Positioning
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 can result in delayed and imprecise control, limiting the use of manual operation modes.
Innovation Solution
A robot cleaner system equipped with a remote control device that uses camera-generated image information to map the actual cleaning region with a virtual region, allowing for precise location and posture determination of the robot cleaner, enabling intuitive and elaborate control through touch inputs and voice commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the robot cleaner uses conventional position detection methods, then the device structure remains simple, but the position measurement precision deteriorates leading to inaccurate location detection
Solution Approach 1:
The patent introduces a recognition device as an intermediary element that the robot cleaner recognizes to determine its position. Instead of using complex sensors or cameras directly on the robot, the system uses simple recognition devices (such as markers or visual cues) placed in the environment that the robot can easily identify and use for position detection, thereby achieving high measurement precision without increasing device complexity
Solution Approach 2:
The patent replaces conventional mechanical or electronic position detection systems with an optical recognition system. The robot cleaner uses image processing and pattern recognition to detect its position based on visual information from the recognition devices, substituting complex mechanical sensors with simpler optical detection methods that achieve higher precision
2Ease of operation
If the user must be in the same area as the robot cleaner for wireless operation, then the control system remains simple, but the ease of operation deteriorates due to delayed and imprecise control
Solution Approach 1:
The patent implements a feedback mechanism where the robot cleaner continuously detects its position using recognition devices and communicates this information to the control system. The system provides real-time feedback about the robot's location and status to the user, enabling the user to control the robot from a distance with precise knowledge of its current position, thereby improving ease of operation without requiring the user to be physically present
Solution Approach 2:
The patent creates a virtual representation or map of the environment and the robot's position within it. This digital copy allows the user to see and control the robot's location and movements remotely through a display interface, eliminating the need for the user to be in the same physical area while maintaining simple control through the copied environmental model
Data Source
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.
