Robot Cleaner Motion Control by User Terminal Tilting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional robot cleaners require users to view a screen on a terminal to control their movement, making operation cumbersome and requiring alternating attention between the terminal and the actual cleaning space.
Innovation Solution
A control method and system that allows users to control a robot cleaner by tilting a user terminal, with signals transmitted based on the terminal's tilt direction and rotation angles, enabling forward, backward, diagonal, and rotational movements without needing to view the terminal's screen.

Engineering Contradiction Analysis
1Measurement precision
If a user terminal screen is used to control the robot cleaner, then the position and direction of the robot cleaner can be confirmed, but the user must alternately view the screen and the actual position, making operation cumbersome
Solution Approach 1:
The patent replaces the mechanical visual confirmation method (viewing the screen) with a sensor-based detection system. The detection unit in the user terminal automatically detects the robot cleaner's position and direction without requiring the user to visually check the screen, thereby substituting a mechanical viewing action with an automated sensing system.
Solution Approach 2:
The user terminal's detection unit performs self-detection of the robot cleaner's position and direction. Instead of requiring the user to manually observe and interpret screen information, the system automatically acquires and processes the positional data, enabling the control operation to proceed without continuous user verification.
2Manufacturing precision
If the user terminal screen is continuously monitored to control the robot cleaner, then accurate control is possible, but the user's attention is constantly required, reducing operational efficiency
Solution Approach 1:
The patent substitutes the mechanical process of continuous visual monitoring with an automated detection system. The detection unit continuously tracks the robot cleaner's position and direction in the background without requiring the user's attention, replacing manual observation with automated sensing and processing.
Solution Approach 2:
The detection unit maintains continuous detection of the robot cleaner's position and direction throughout the operation. This ensures that the control signals are always based on up-to-date positional information, maintaining control accuracy without requiring intermittent user intervention or screen checking.
3Adaptability or versatility
If conventional remote control methods are used, then the robot cleaner can be controlled, but the operation requires user manipulation and screen viewing, increasing complexity
Solution Approach 1:
The patent replaces the mechanical interaction of manually operating controls and viewing screens with a sensor-based detection system. The detection unit automatically acquires positional information and the controller generates appropriate control signals, substituting complex manual operations with automated sensing and signal generation.
