Autonomous Delivery Routing for Moving Table Destinations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous mobile devices face challenges in delivering items to dynamic delivery destinations, especially in environments with changing layouts, such as cafés, where the position of delivery objects like tables may change, leading to failed delivery attempts due to outdated path information.
Innovation Solution
An autonomous delivery system that includes an imaging device, a mark management server, and an autonomous mobile device, which continuously updates mark information about the delivery area, allowing the system to generate and adjust delivery paths in real-time based on new object positions and shapes, ensuring reliable delivery even if the delivery destination's position changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the autonomous mobile device uses predetermined path information for delivery, then the device can operate with simple navigation, but the delivery fails when the delivery destination position changes
Solution Approach 1:
The system continuously updates mark information about delivery destinations and uses this feedback to dynamically adjust delivery paths. The mark management server receives updated position information and communicates it back to the autonomous device, ensuring the device always has current destination locations without requiring complex manual reprogramming
Solution Approach 2:
The system pre-establishes mark information for delivery destinations before actual delivery operations begin. This preliminary setup allows the autonomous device to quickly adapt to position changes by referencing pre-configured mark data, rather than requiring complex real-time calculations when changes occur
2Reliability
If the autonomous mobile device continuously updates path information to adapt to changing delivery destinations, then delivery reliability improves, but the system complexity and computational load increase
Solution Approach 1:
The mark management server acts as an intermediary between the imaging device that captures delivery destination positions and the autonomous mobile device that performs deliveries. This intermediary handles the complex tasks of receiving, processing, and storing mark information, while providing simplified updated position data to the autonomous device, thus distributing system complexity away from the mobile device itself
Solution Approach 2:
The system uses mark information as a simplified representation or copy of the actual delivery destination positions and characteristics. Instead of processing complex real-time spatial data, the system works with structured mark information that captures essential position data, reducing computational requirements while maintaining delivery accuracy

AI summary
An autonomous mobile device includes a communicator, a map information storage, a mover, a path generator, and a moving controller. The communicator receives first mark information stored in a mark information storage from a mark management server device. The map information storage stores map information concerning a delivery area. The mover moves the autonomous mobile device. The path generator sets a first object to which a first mark is attached as a first delivery destination, and generates a path from a moving start position of the autonomous mobile device to the first delivery destination based on the first mark information and the map information. The moving controller controls the mover to move the autonomous mobile device to the first delivery destination based on the path.
