Hybrid Drone-Robot Delivery via Intermediate Handoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional delivery systems using drones face challenges in smoothly delivering packages to the intended addressee, as they rely solely on unmanned flying objects, which lack the capability of direct interaction with recipients.
Innovation Solution
An unmanned delivery system that combines a self-propelled robot and an unmanned aerial vehicle, where the aerial vehicle transports the package to an intermediate location and the robot delivers it to the recipient's address, utilizing autonomous and remote operation modes to ensure smooth delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a delivery system uses only an unmanned aerial vehicle to transport packages, then automation is improved, but the ability to smoothly deliver to the addressee deteriorates
Solution Approach 1:
The delivery system is divided into two functional segments: an unmanned aerial vehicle for long-distance transportation to an intermediate location, and a self-propelled robot for final ground delivery to the addressee. This segmentation allows each component to specialize in its optimal delivery mode while maintaining overall automation.
Solution Approach 2:
An intermediate location is introduced as a mediator between the aerial vehicle's drop-off point and the final destination. The self-propelled robot acts as an intermediary that receives packages at this intermediate location and completes the delivery, bridging the gap between automated aerial transport and personalized ground delivery.
2Device complexity
If a delivery system uses only an unmanned aerial vehicle, then device complexity is reduced, but delivery reliability deteriorates
Solution Approach 1:
The system segments the delivery function into aerial transport and ground delivery, with each segment handled by a specialized device. This division allows the aerial vehicle to focus on efficient long-distance transport while the self-propelled robot ensures reliable final delivery, collectively improving overall system reliability.
Solution Approach 2:
The system changes the operational parameters by introducing a hybrid delivery mode: aerial transport for the first leg and ground-based autonomous delivery for the final leg. This parameter change enables the system to leverage the advantages of both delivery modes, improving reliability without excessive complexity.
3Ease of operation
If a delivery system uses a self-propelled robot for final delivery, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The self-propelled robot serves as an intermediary device that operates at an intermediate location between the aerial vehicle and the addressee. This intermediary approach allows the complex robot functionality to be isolated to only the final delivery segment, rather than requiring the entire delivery system to be ground-based.
Solution Approach 2:
The self-propelled robot is designed with multi-functionality, capable of autonomous navigation, package handling, and interaction with addressees. By consolidating these functions into a single versatile robot platform, the system achieves smooth delivery operation without proportionally increasing overall complexity.
