UAV to UGV Package Handover via Server Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional unmanned delivery systems, there is no structural system to link unmanned aerial delivery vehicles (UAVs) and unmanned ground delivery vehicles (UGVs), preventing UAVs from identifying the position of UGVs on the ground to transfer packages and UGVs from acquiring delivery destination information.
Innovation Solution
A delivery method and system where UAVs acquire transfer position information for UGVs and UGVs acquire delivery destination information, enabling UAVs to pass packages to UGVs and UGVs to deliver them closer to the final destination autonomously.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an unmanned aerial delivery vehicle is used to transport packages, then the package can be delivered to areas not accessible by ground vehicles, but the vehicle cannot identify the position of ground vehicles for package transfer
Solution Approach 1:
The patent implements a feedback mechanism where the unmanned ground delivery vehicle transmits its position information to a server, which then provides this information back to the unmanned aerial delivery vehicle. This feedback loop enables the aerial vehicle to identify and navigate to the correct transfer position on the ground, resolving the information loss problem while maintaining delivery area versatility
Solution Approach 2:
The patent introduces a server as an intermediary that facilitates communication between the unmanned aerial delivery vehicle and the unmanned ground delivery vehicle. The server collects position information from ground vehicles and transmits it to aerial vehicles, enabling indirect information exchange that solves the position identification problem without requiring direct vehicle-to-vehicle communication
2Ease of operation
If an unmanned ground delivery vehicle is used to transport packages, then the package can be delivered closer to the final destination, but the vehicle cannot acquire delivery destination information from the aerial vehicle
Solution Approach 1:
The patent establishes a feedback mechanism where the unmanned aerial delivery vehicle transmits delivery destination information to the server, which then provides this information to the unmanned ground delivery vehicle. This enables the ground vehicle to acquire the necessary destination information to complete the final delivery segment
Solution Approach 2:
The server acts as an intermediary that receives delivery destination information from the aerial vehicle and transmits it to the ground vehicle. This intermediary approach solves the information transfer problem between different vehicle types, enabling seamless handover and final delivery
3Adaptability or versatility
If a structural system linking aerial and ground vehicles is implemented, then package transfer between vehicles becomes possible, but the system complexity increases
Solution Approach 1:
The patent uses a server as an intermediary to manage the linkage between aerial and ground vehicles. Instead of creating complex direct communication and coordination systems between vehicles, the server centralizes information management, simplifying the overall system structure while enabling versatile vehicle linkage and package transfer capabilities
Data Source
AI summary
An unmanned aerial delivery vehicle acquires transfer position information indicating a position at time of package transfer of an unmanned ground delivery vehicle that receives a package in a case where a predetermined condition based on position information of the unmanned aerial delivery vehicle that transports a package is satisfied. A position of the unmanned ground delivery vehicle at the time of package transfer is identified by the unmanned aerial delivery vehicle. The unmanned ground delivery vehicle acquires delivery destination information of the package transported by the unmanned aerial delivery vehicle.
