Touch-Controlled Drone Hovering for Precise Manual Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operating an unmanned flying object, such as a multicopter, requires fine remote control skills, making it difficult for beginners to accurately move the device to a desired position, especially when using a smartphone-based first-person view (FPV) application.
Innovation Solution
The unmanned flying object is equipped with detectors that detect a user's touch operation, allowing the controller to adjust the rotations of the electric motors based on the user's physical interactions, enabling direct hand control and simplifying the movement of the device.

Engineering Contradiction Analysis
1Measurement precision
If a remote controller is used to operate the unmanned flying object, then the flying object can be controlled to move to a desired position, but fine remote control operation is difficult for beginners
Solution Approach 1:
The patent introduces a touch detection interface as an intermediary between the user and the motor control system. Instead of directly controlling motors through complex remote control signals, the user touches the airframe surface, and the touch position and pressure are detected by detectors and converted into appropriate motor control commands by the controller, simplifying the operation while maintaining positioning precision
Solution Approach 2:
The patent replaces the mechanical remote control operation system with a touch-based detection system. The traditional mechanical control linkage is substituted with detectors that sense touch operations on the airframe and convert them into electronic control signals, making the system more intuitive and easier to operate for beginners
2Ease of operation
If touch detectors are added to detect user's touch operation, then direct hand control is enabled for easier operation, but device complexity increases
Solution Approach 1:
The airframe surface serves multiple functions: it maintains the aerodynamic structure of the flying object and simultaneously acts as a touch-sensitive control interface. The detectors integrated into the airframe detect touch operations, allowing the same physical surface to function both structurally and as a user interface, avoiding the need for separate control mechanisms
Solution Approach 2:
The patent merges the touch detection function with the existing airframe structure. The detectors are integrated into the airframe surface, combining the structural component with the sensing function, thereby reducing overall system complexity compared to having separate control interfaces

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