Somatosensory UAV Remote Control With Headless Direction Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing somatosensory remote controllers for UAVs require operators to maintain a fixed position, posing high technical demands and making it difficult to control UAVs beyond visual range due to the need to locate the UAV's head, which increases safety risks.
Innovation Solution
A somatosensory remote controller system with a motion sensor, controller, and transmission module that allows any position of the remote controller to be considered as the center, enabling Bluetooth, WiFi, infrared, mobile network, or wired transmission of flight instructions to an on-board flight control system, and a head-less control method that calculates the heading angle of the remote controller relative to the UAV in real-time to adjust the UAV's flight attitude.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the remote controller body is placed at the center position (fixed position), then the somatosensory remote controller can control the UAV, but the operator's operation is not facilitated and the technical level requirement is high
Solution Approach 1:
The patent transforms the fixed center position requirement into a dynamic reference system. The motion sensor continuously tracks the remote controller's position and orientation, allowing the reference point to move dynamically with the operator's hand movements. This resolves the contradiction by making the control system adaptive to operator position changes while maintaining control accuracy.
Solution Approach 2:
The patent replaces the mechanical requirement of physically positioning the remote controller at a fixed center point with an electronic solution using motion sensors and coordinate transformation algorithms. The motion sensor detects accelerometer and gyroscope data to calculate the remote controller's spatial position, substituting the need for manual mechanical positioning with automated electronic tracking.
2Measurement precision
If the operator needs to locate the remote controller center position, then control precision is maintained, but the operation becomes complex and time-consuming
Solution Approach 1:
The patent performs preliminary action by pre-establishing a coordinate transformation relationship between the remote controller and the UAV. The system pre-calculates the transformation matrix based on the motion sensor data, so that when the operator moves the remote controller, the control signal is automatically transformed without requiring real-time manual positioning calculations, thus saving time while maintaining precision.
3Adaptability or versatility
If the UAV flies beyond visual range, then the operational range is extended, but the operator cannot distinguish the head direction and control accuracy deteriorates
Solution Approach 1:
The patent introduces an intermediary coordinate transformation system that mediates between the operator's remote controller movements and the UAV's flight attitude. The motion sensor acts as an intermediary device that captures the remote controller's orientation and uses transformation matrices to convert these movements into accurate flight direction commands, maintaining control precision even when the UAV is beyond visual range.
Solution Approach 2:
The patent replaces the visual mechanical method of aligning the remote controller with the UAV's head direction with an electronic sensor-based system. The motion sensor continuously tracks the remote controller's orientation and uses algorithmic transformation to determine flight direction, eliminating the need for visual confirmation while maintaining directional accuracy.
