Cleaning Robot Area Selection via QR-Guided Mobile Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cleaning robot control methods require a mobile device with a specific application installed, making it inconvenient for all family members to designate cleaning areas, especially for devices without the application.
Innovation Solution
A method using a mobile device to capture images of a two-dimensional code on a cleaning robot, establishing a wireless connection, and specifying cleaning areas through a touch display, allowing the robot to navigate and clean based on indoor maps and user-defined coordinates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a specific application is installed on the mobile device to control the cleaning robot, then the cleaning area can be designated on the indoor map, but the system becomes inaccessible to family members without the application installed
Solution Approach 1:
The patent introduces a two-dimensional code as an intermediary between the cleaning robot and mobile devices. The code contains encoded position information that acts as a universal interface, allowing any mobile device with a camera to interact with the robot without requiring a dedicated application. This mediator enables family members with different devices to specify cleaning areas equally.
Solution Approach 2:
The patent replaces the traditional application-based control mechanism with an optical recognition system. Instead of requiring software installation and complex app navigation, the system uses camera-based two-dimensional code scanning to transmit control commands. This substitution simplifies the interaction mechanism and removes the barrier of application installation requirements.
2Measurement precision
If the cleaning area is designated only through the indoor map in the application, then the cleaning robot can navigate accurately, but the control method is not convenient for all family members to use
Solution Approach 1:
The patent pre-encodes position information into two-dimensional codes that are physically placed at specific locations in the environment. This preliminary encoding of spatial data allows users to simply scan codes to designate cleaning areas, eliminating the need for complex map navigation and area drawing operations. The position information is prepared in advance in the codes, ensuring both accuracy and convenience.
Solution Approach 2:
The patent uses two-dimensional codes as simplified copies or representations of complex indoor map coordinates. Instead of requiring users to interact with detailed digital maps and draw polygons, the system uses compact code symbols that encode position information. Scanning a code creates a copy of the location data, enabling accurate area specification through a simple tapping action rather than complex map manipulation.

AI summary
A method for specifying a cleaning area to a cleaning robot without an in-built map provides a hand-held mobile device capturing a two-dimensional code label arranged on a top of a cleaning robot parked on a charging base, and obtaining a positional relationship between the mobile device and the cleaning robot through the captured image. The cleaning robot is controlled to enter a cleaning mode under the guidance of the mobile device. With captured images, a user can specify an area within the environment for cleaning, and through a touch display screen can control the cleaning robot to go to the specified cleaning area for cleaning. The mobile device and the cleaning robot employing the method are also disclosed.
