Cleaning robot and method for controlling cleaning robot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cleaning robots lack the ability to intuitively display their state and changes in state to users, requiring manual checking and positioning, which complicates user control and cleaning efficiency.
Innovation Solution
A cleaning robot with a user interface that displays a map image of divided regions, showing the state of the robot through icons indicating cleaning, completion, or errors, allowing users to control the robot via a virtual wall and target points for efficient cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the cleaning robot operates autonomously without user intervention, then cleaning productivity is improved, but the user cannot monitor or control the robot's state
Solution Approach 1:
The patent implements a feedback mechanism by displaying the robot's current state (cleaning, charging, error conditions) and location on a map through a user interface. This allows users to monitor the autonomous robot's operations in real-time, resolving the information loss while maintaining productivity.
Solution Approach 2:
The patent introduces a remote controller with a map display as an intermediary between the user and the cleaning robot. This intermediary device provides visual feedback about the robot's state and position, enabling users to monitor and control the robot without direct physical interaction.
2Measurement precision
If the user directly controls the cleaning robot to reach specific positions, then positioning accuracy is improved, but operation complexity increases
Solution Approach 1:
The patent creates a virtual copy of the physical environment as a navigable map displayed on the remote controller. Users can select target positions on this 2D map representation, and the system automatically translates these selections into precise navigation commands for the robot, simplifying the control process while maintaining positioning accuracy.
Solution Approach 2:
The patent transforms the 3D physical navigation problem into a 2D map interface problem. Users interact with a simplified 2D representation of the environment, selecting destinations by tapping on the map rather than manually controlling the robot's movement, which reduces operational complexity while achieving accurate positioning.
3Reliability
If the cleaning robot cleans the entire space without region division, then cleaning completeness is improved, but cleaning time increases
Solution Approach 1:
The patent divides the cleaning space into multiple regions represented on the map interface. Users can select specific regions for cleaning, allowing the robot to focus on particular areas rather than systematically cleaning the entire space, thereby reducing cleaning time while maintaining completeness within the selected regions.
Solution Approach 2:
The patent enables partial cleaning by allowing users to select only the regions that need cleaning at a given time. This partial action approach reduces the overall cleaning duration by concentrating resources on specific areas rather than attempting to clean the entire space uniformly.

AI summary
A cleaning robot includes a user interface to display a map image including one or more divided regions, and the user interface displays an icon corresponding to a state value of a main device on the map image.
