Autonomous Movement Priority Control for Multi-Body Interference Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for managing the movement of autonomous moving bodies, such as UAVs, ships, and automobiles, do not effectively consider the positional relationships and priorities among multiple moving entities, leading to difficulties in setting appropriate behaviors and avoiding interference, especially in environments with changing conditions like weather or bird presence.
Innovation Solution
A management system that includes a movement managing section capable of determining and comparing priority/subordination degrees among moving bodies based on individual information, allowing autonomous decision-making and route adjustments without direct communication, using a priority/subordination determining section, comparing section, and adjusting section to ensure safe and efficient movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the position of a UAV is compared to a flight-restricted region and avoidance measures are enacted, then the UAV can avoid intruding into no-fly zones, but the system does not consider the positional relationship between multiple flying bodies leading to potential interference
Solution Approach 1:
The system segments the complex spatial management problem into individual priority assessments for each moving body. The priority/subordination determining section evaluates each body independently based on its own characteristics (speed, size, direction, environmental factors) rather than attempting to manage all positional relationships simultaneously, thereby improving both reliability and adaptability.
2Reliability
If autonomous moving bodies communicate directly with each other to coordinate movements, then interference can be avoided, but communication difficulties and environmental factors may disrupt coordination
Solution Approach 1:
The system introduces a management server as an intermediary that receives information from all autonomous moving bodies and distributes priority/subordination information. This mediator approach allows coordinated movement management without requiring direct peer-to-peer communication between moving bodies, reducing communication complexity while maintaining reliability.
Solution Approach 2:
Each autonomous moving body autonomously determines its own priority/subordination degree based on information received from the management server and its own characteristics. The bodies self-adjust their behavior according to the determined priority without needing continuous communication or coordination protocols, thereby simplifying the communication requirements while ensuring reliable movement coordination.
3Ease of operation
If the system establishes direct communication between moving bodies for route coordination, then appropriate behaviors can be set, but communication establishment may be difficult under certain conditions
Solution Approach 1:
The management server acts as a central intermediary that facilitates information exchange between moving bodies. Instead of requiring direct communication links between each pair of moving bodies, the server receives information from all bodies and distributes relevant priority information, making the system easier to operate while maintaining reliable information exchange even when direct communication is difficult.

AI summary
A management system comprises a movement management unit that communicates via a communication device with a plurality of moving bodies including an autonomous moving body provided with an autonomous control unit for moving autonomously, and that manages the movement of the plurality of moving bodies. The movement management unit comprises a priority/subordination determination unit that determines the degree of priority/subordination relating to the respective movements of the plurality of moving bodies on the basis of individual information of the moving bodies. The autonomous moving body comprises: a priority/subordination comparison unit that compares another priority/subordination degree, which is a degree of priority/subordination determined by the priority/subordination determination unit for another moving body that is a moving body, from among the plurality of moving bodies, different from the autonomous moving body, and the host priority/subordination degree, which is a degree of priority/subordination determined by the priority/subordination determination unit for the autonomous moving body; or a priority/subordination reception unit that receives the comparison results of the host priority/subordination degree and the other priority/subordination degree obtained by comparisons by the moving body management unit.
