Autonomous Moving Body Priority Control at Shared Waypoints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous moving bodies operating independently under different systems or without communication face challenges in coordinating movement paths, leading to potential collisions at via or destination points, hindering smooth task execution.
Innovation Solution
An autonomous moving body equipped with external sensors to recognize other moving bodies and determine movement priorities based on task urgency, using a movement determination unit to control its path and potentially suspend movement to avoid collisions, even when not part of a centralized system or communicating with others.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If autonomous moving bodies operate independently under different systems without centralized control, then device complexity and system integration requirements are reduced, but collision risk at via points or destination points increases
Solution Approach 1:
Each autonomous moving body independently determines movement priority and controls its own movement without requiring centralized control or communication with other bodies. The moving body reads remaining capacity information from other bodies' presentation units and autonomously decides whether to suspend or continue movement based on estimated task priorities, achieving collision avoidance through self-service decision-making
Solution Approach 2:
The presentation unit serves as an intermediary information display device that presents remaining capacity information to other autonomous moving bodies. This allows indirect information exchange without requiring direct communication systems, enabling priority-based collision avoidance while maintaining system independence
2Reliability
If autonomous moving bodies suspend movement to avoid collisions at via points or destination points, then collision risk is reduced, but task execution efficiency decreases
Solution Approach 1:
The system changes the parameter of movement state (continuing or suspending) based on dynamic priority comparison. By reading remaining capacity information and estimating task priorities, the moving body determines whether to suspend movement only when necessary, optimizing the balance between collision avoidance and task execution efficiency through parameter-based decision-making

AI summary
Provided is an autonomous moving body configured to move along a planned movement path, including: an external sensor configured to recognize another autonomous moving body and an operation state of the another autonomous moving body; a movement determination unit configured to determine, when it is predicted by the external sensor that the another autonomous moving body is positioned at a via point or a destination point of the own autonomous moving body at the same time that the own autonomous moving body is, whether to continue or suspend movement based on whether a task of the another autonomous moving body estimated from the operation state or a task of the own autonomous moving body has a higher priority; and a movement control unit configured to control a moving unit based on the determination of the movement determination unit.
