Autonomous Vehicle Alignment for Precise UAV Goods Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current unmanned aerial vehicle (UAV) delivery systems face challenges in accurately unloading goods at designated positions, leading to reduced reliability and potential damage due to external factors like rain and wind, as the goods may not be precisely positioned within the storage area.
Innovation Solution
An autonomous vehicle system that collaborates with UAVs by using sensing data such as optical signals, images, and distance measurements to adjust its position relative to the UAV, ensuring accurate and safe transfer of goods through mechanisms like folding poles, air mats, or lifting units, allowing for precise alignment and unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If goods are unloaded by unmanned aerial vehicle at designated position, then delivery speed is improved, but unloading precision deteriorates leading to goods loss or damage
Solution Approach 1:
An autonomous vehicle is introduced as an intermediary between the unmanned aerial vehicle and the final destination. The autonomous vehicle receives goods from the UAV and then delivers them to the designated position with high precision, allowing the UAV to focus on rapid delivery while the ground vehicle handles precise positioning.
Solution Approach 2:
The delivery process is divided into two separate stages: first, the UAV performs rapid long-distance transport to a general delivery area; second, the autonomous vehicle completes the final precise delivery to the exact designated position. This segmentation allows each component to optimize for its specific function.
2Manufacturing precision
If autonomous vehicle adjusts relative position with unmanned aerial vehicle through movement, then goods unloading accuracy is improved, but system complexity increases
Solution Approach 1:
The autonomous vehicle autonomously adjusts its own position relative to the UAV using its movement capabilities. The vehicle's control system independently processes sensing data and executes position adjustments without requiring complex external coordination systems, thereby improving unloading accuracy while managing system complexity through self-service automation.
3Manufacturing precision
If sensing data is used to adjust position during goods takeover, then unloading precision is improved, but measurement and detection difficulty increases
Solution Approach 1:
The autonomous vehicle performs preliminary position adjustment based on sensing data before the actual goods unloading operation. By pre-adjusting the relative position between the vehicle and UAV, the system ensures optimal positioning is achieved before the critical unloading moment, improving precision while allowing time for sensing data processing.

AI summary
Provided is a method for an autonomous vehicle to handle goods in collaboration with an unmanned aerial vehicle. The method comprises recognizing an unmanned aerial vehicle loading goods by the autonomous vehicle, capturing an image of the recognized unmanned aerial vehicle by the autonomous vehicle, analyzing the captured image to recognize a marker by the autonomous vehicle, adjusting a relative position of the autonomous vehicle and the unmanned aerial vehicle by moving the autonomous vehicle based on a recognition result of the marker, and taking over the goods from the unmanned aerial vehicle by the autonomous vehicle after position adjustment is completed.
