Robot Cleaner Tilt Control Without Screen Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot cleaners require users to view the screen of a user terminal to control their movement, which is inconvenient and requires alternating attention between the terminal and the actual robot cleaner.
Innovation Solution
A robot cleaner with a wireless communication unit that receives signals from a user terminal equipped with a tilt sensor, allowing the controller to drive the robot cleaner based on the tilt direction, enabling operation without needing to view the terminal screen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user terminal screen is used to control the robot cleaner, then the control functionality is achieved, but the user must alternately view the screen and the actual robot cleaner, reducing ease of operation
Solution Approach 1:
The patent replaces the mechanical/visual control method (viewing screen and manually controlling) with an inertial sensing system. The tilt sensor detects the user's natural tilting motion, and the controller automatically converts this into corresponding robot movement commands, eliminating the need for visual screen monitoring.
Solution Approach 2:
The system enables self-service control where the robot cleaner autonomously interprets and executes movement commands based on inertial sensor data from the user terminal. The controller automatically processes tilt signals and adjusts wheel motors without requiring user intervention or screen viewing.
2Ease of operation
If the conventional control method is used, then the robot cleaner can be controlled, but the operation becomes complex and inconvenient
Solution Approach 1:
The patent replaces complex manual control operations with inertial sensing. The tilt sensor and accelerometer automatically capture user intent through natural device tilting, and the controller translates this into coordinated wheel motor commands, simplifying the control interface to intuitive physical motion.
Solution Approach 2:
The user terminal serves multiple functions: it acts as both the control interface and the sensing device. The inertial sensor unit within the terminal handles both detection and control signal generation, eliminating the need for separate control devices or complex button interfaces.
3Measurement precision
If visual screen control is required, then precise control is possible, but user convenience is reduced
Solution Approach 1:
The patent substitutes visual-screen-based precise control with inertial sensor-based control. The tilt sensor and accelerometer provide precise measurement of user tilt angle and direction, enabling accurate robot positioning through natural user motion without requiring visual feedback.
