Autonomous Delivery Robot Door-Status Authentication for Secure Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing home delivery systems do not effectively authenticate recipients during face-to-face package delivery, lacking mechanisms for secure and simple authentication when a mobile body delivers a package to a designated destination.
Innovation Solution
A mobile body equipped with processors that acquire door status information to determine if the entrance door is open, authenticate the delivery, and unlock a locking device only when the door is open, ensuring secure and reliable package delivery by verifying the recipient's personal information if necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If face-to-face delivery is implemented without authentication, then delivery convenience is improved, but security and reliability deteriorate
Solution Approach 1:
The system performs preliminary authentication by detecting door opening status before the mobile body arrives at the destination. This advance detection allows the system to prepare for authenticated delivery, ensuring security is established before the delivery interaction occurs, thus resolving the contradiction between convenience and reliability.
Solution Approach 2:
The system uses feedback from door status information (open/closed state) to dynamically control the locking device. When the door is detected as open, the locking device is unlocked to enable delivery; when closed, it remains locked. This feedback mechanism ensures secure delivery while maintaining operational simplicity.
2Reliability
If complex authentication procedures are implemented, then authentication reliability is improved, but operational complexity and recipient inconvenience increase
Solution Approach 1:
The system performs authentication automatically by detecting the door opening status without requiring the recipient to actively participate in the authentication process. The mobile body autonomously determines whether to unlock based on door status, eliminating the need for complex manual authentication procedures while maintaining security.
Solution Approach 2:
The system replaces traditional mechanical or manual authentication methods with an automated sensor-based detection system. The door status information acquired by the mobile body serves as the authentication trigger, substituting complex verification procedures with a simple, reliable physical state detection.
3Productivity
If the locking device remains unlocked after authentication, then delivery speed is improved, but security and risk of unauthorized access deteriorate
Solution Approach 1:
The system implements periodic monitoring of door status after unlocking the locking device. The mobile body continuously checks whether the door remains open or has been closed, and accordingly maintains or re-locks the package. This periodic verification ensures rapid delivery when the door is open while preventing unauthorized access if the door is closed.
Solution Approach 2:
The system uses real-time feedback from door status monitoring to dynamically control the locking device state. When the door is detected as closed after unlocking, the system re-locks the package immediately, providing continuous security adjustment based on environmental conditions while enabling fast delivery when appropriate.

AI summary
A mobile body delivers a package to a designated destination by autonomous traveling. When the mobile body arrives at the destination, door status information including opening/closing status of an entrance door of the destination is acquired, and it is determined whether the entrance door of the destination has been opened based on the acquired door status information. When the entrance door has been opened, a delivery of the package to the destination is authenticated, and a locking device for regulating the delivery of the package from the mobile body is unlocked.
