Touch-Guided Drone Hover Control for Precise Hand Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote controllers for unmanned flying objects, whether traditional or smartphone-based, require fine operations for accurate movement, making it difficult for beginners to maneuver these objects to desired positions.
Innovation Solution
The unmanned flying object incorporates a system with multiple rotors, touch-sensitive detectors, and multiple flight modes, allowing users to physically interact with the object to move it by hand, and automatically adjusts flight modes based on user input to facilitate easier operation and precise positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a remote controller is used to operate the unmanned flying object, then the flying object can be controlled to move to desired positions, but fine remote control operations are required which are difficult for beginners
Solution Approach 1:
The patent introduces a touch-sensitive detector as an intermediary between the user and the flying object. Instead of requiring complex remote control operations, the user simply touches the airframe directly, and the detector converts this simple tactile input into control signals that move the flying object to the desired position.
Solution Approach 2:
The patent replaces the traditional mechanical remote control system with a touch-sensitive detection system. The control mechanism transitions from manual manipulation of remote controls to automatic detection of touch inputs on the airframe, simplifying the user interaction model.
2Ease of operation
If touch-sensitive detectors are added to enable hand operation, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The touch-sensitive detector serves multiple functions: it detects user touch inputs, determines the touched position on the airframe, and generates corresponding control signals. This multi-functionality reduces the need for separate control mechanisms, offsetting the added complexity with functional consolidation.
Solution Approach 2:
The flying object becomes self-responsive to user inputs. When a user touches the airframe, the system automatically detects the touch, processes the position information, and executes the movement without requiring additional control equipment or complex intermediary systems.

AI summary
Detectors 110 detect a user's touch operation to an airframe, and a motor control unit 122 controls rotations of motors 4a to 4d, based on the user's touch operation detected by the detectors 110. The motor control unit 122 is configured to have a hovering function of making the airframe automatically perform a stationary flight at a hovering position. The motor control unit 122 keeps the setting of the hovering function off during a period while the detectors 110 are detecting a user's touch operation, and when the detectors 110 stop detecting a user's touch operation, the motor control unit 122 sets the hovering function on.
