UAV Mid-Air Capture Using Target State Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for collecting a target object falling through the air, such as a UAV, are not effective when the falling route of the object fluctuates due to weather conditions or lack of propulsive force.
Innovation Solution
A method and system that utilize an unmanned aerial vehicle (UAV) to collect a target object falling through the air by transmitting state information, including position and velocity, from the target object to the UAV, which then flies accordingly to capture the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a collection net is placed horizontally on the ground to collect a UAV, then the UAV can be collected without propulsive force, but the collection area becomes large and the falling route cannot accommodate fluctuations
Solution Approach 1:
The patent applies dynamics by enabling the UAV to actively adjust its flight path in real-time based on received position information. Instead of a static collection method with a fixed net, the UAV dynamically modifies its trajectory to intercept the target object, allowing the collection system to adapt to falling route fluctuations while maintaining a compact collection area.
Solution Approach 2:
The patent implements feedback by continuously transmitting position information from the target object to the collecting UAV and using this information to adjust the UAV's flight path. This closed-loop control system allows the UAV to respond to real-time changes in the target's position, ensuring reliable collection even when the falling route varies.
2Device complexity
If the target object falls through the air without propulsive force, then equipment complexity is reduced, but the falling route fluctuates due to weather conditions
Solution Approach 1:
The patent applies self-service by equipping the target object with minimal equipment (position information transmission capability) rather than requiring the collecting UAV to have complex interception mechanisms. The target object essentially serves itself by providing location data, while the collecting UAV uses this information to perform the collection task.
Solution Approach 2:
The patent compensates for the lack of propulsive force in the target object by making the collecting UAV dynamic and adaptive. The UAV adjusts its flight path in real-time based on received position information, allowing the system to handle falling route fluctuations without adding complexity to the target object.
3Measurement precision
If the collecting UAV flies to capture the target object based on transmitted position information, then collection accuracy is improved, but flight time and energy consumption increase
Solution Approach 1:
The patent uses feedback to improve collection accuracy by continuously receiving position information from the target object and adjusting the UAV's flight path accordingly. This real-time information allows the UAV to optimize its approach, reducing unnecessary flight time while maintaining high collection accuracy.
Solution Approach 2:
The patent applies preliminary action by having the target object transmit its position information before the UAV begins its final approach. This advance information allows the UAV to plan an optimized flight path, reducing the time required for the collection maneuver while maintaining accuracy.
