Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for controlling Unmanned Aerial Vehicles (UAVs) are either expensive due to the need for expert human pilots or difficult to fine-tune, especially when replicating trajectories multiple times, as they rely on RC transmitters or GUI-generated fixed control programs that are hard to modify quickly.
Innovation Solution
A remote control system with moveable control members, actuators, and processing circuits that allow users to adjust and sense torque settings based on a predetermined trajectory, enabling real-time modification of UAV flight paths by transmitting user input to the UAV for dynamic control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If expert human pilots are used to control UAV trajectories, then precise control and adaptability are improved, but cost and operator fatigue increase
Solution Approach 1:
The system records expert pilot control inputs during a示范 flight and stores them as a control program. This copied control sequence can then be replayed multiple times without additional cost or fatigue to the expert pilot, while maintaining the same control precision.
Solution Approach 2:
The expert pilot performs the control task once to record the optimal control sequence in advance. This preliminary action captures the precise control strategy, which is then stored and reused for multiple flights, eliminating the need for repeated expert intervention.
2Measurement precision
If fixed control programs are generated via GUI, then trajectory replication precision is improved, but ease of modification deteriorates
Solution Approach 1:
The control program is designed to be dynamically adjustable. Users can modify control parameters such as speed, altitude, and trajectory points directly in the control interface, and these modifications are immediately reflected in the flight execution without requiring complete program rewriting.
Solution Approach 2:
The control program is divided into discrete control segments or keyframes that can be independently modified. This segmentation allows users to make localized adjustments to specific portions of the trajectory while maintaining the integrity of the overall flight program.
3Adaptability or versatility
If RC transmitter is used for manual control, then adaptability to external influences is improved, but trajectory replication precision deteriorates
Solution Approach 1:
The system provides real-time feedback to the user about the current flight state and deviation from the reference trajectory. This feedback loop enables users to make informed adjustments while maintaining overall trajectory fidelity, combining the benefits of manual adaptability with automated precision.
