Multimodal Logistics UAV-AGV Handoff System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commercial adoption of unmanned aerial vehicles (UAVs) in order fulfillment is hindered by safety issues, flight controller distractions, aircraft collisions, privacy concerns, and insurance challenges, as well as inefficiencies in traditional distribution networks.
Innovation Solution
A system that integrates UAVs with autonomous ground vehicles (AGVs) and docking stations, allowing for multimodal logistics where UAVs transfer items to AGVs at designated points, enabling efficient navigation and delivery through a coordinated fulfillment system that manages flight paths, item transfer, and route calculations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If UAVs are used for direct-to-consumer delivery, then delivery speed and coverage are improved, but safety risks and flight controller distractions increase
Solution Approach 1:
The patent introduces AGVs as intermediary vehicles that receive items from UAVs at transfer points and complete the final delivery. This multi-modal approach allows UAVs to operate at higher speeds for long-distance transport while AGVs handle the safer, ground-based final mile delivery, thus improving overall delivery speed while maintaining safety through the intermediary ground vehicle system.
2Productivity
If UAVs operate autonomously in complex environments, then labor costs are reduced, but aircraft collisions and privacy concerns increase
Solution Approach 1:
The delivery system is segmented into distinct phases: UAV-based long-distance transport to transfer points, and AGV-based final delivery. This segmentation allows UAVs to operate in open skies with reduced collision risks compared to navigating complex urban environments, while still achieving labor cost reductions through autonomous operation. The transfer points serve as designated zones where UAVs can safely deposit items without requiring complex maneuvering in populated areas.
3Ease of manufacture
If traditional distribution networks are used, then infrastructure is already established, but delivery efficiency and flexibility are reduced
Solution Approach 1:
The patent merges the advantages of traditional distribution networks (established infrastructure for AGV operations) with the flexibility of UAV technology. AGVs utilize existing road networks and infrastructure, while UAVs provide flexible, direct aerial transport to transfer points. This combination allows the system to leverage existing infrastructure while achieving improved delivery efficiency through the autonomous multi-modal platform.

AI summary
An example system may comprise a docking station remotely located from a fulfillment center, a fulfillment system, an unmanned aerial vehicle (UAV), and an autonomous ground vehicle (AGV). The fulfillment system manages the fulfillment center and the docking station, receives a request to ship an item, determines an item transfer point based on a delivery point, and calculates a flight path to the item transfer point. The fulfillment system loads the item at the fulfillment center via a handling mechanism of the UAV and deploys the UAV to the item transfer point using the flight path. The AGV is coupled for wireless communication with the fulfillment system, the docking station, and the AGV. The item transfer point indicates a geographical location where the item is to be transferred from the UAV to one of the docking station and the AGV based on the delivery point.
