Autonomous Moving Body Collision Avoidance Without Intercommunication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous moving bodies face challenges in coordinating their paths when executing different tasks in the same environment without a single control system or intercommunication, leading to potential collisions and reduced efficiency.
Innovation Solution
An autonomous moving body equipped with external sensors, an avoidance determination unit, and a movement control unit that allows it to recognize and avoid other moving bodies based on their operation states and task priorities, even without a shared control system or communication, by generating avoidance paths and controlling movements accordingly.

Engineering Contradiction Analysis
1Extent of automation
If multiple autonomous moving bodies execute different tasks in the same environment without a single control system or intercommunication, then each body can operate independently and maintain its own task execution, but collisions between moving bodies occur and work efficiency is reduced
Solution Approach 1:
Each autonomous moving body independently performs collision avoidance by using its own external sensor to detect other moving bodies, its own avoidance determination unit to predict contact possibilities, and its own movement control unit to execute avoidance maneuvers, without relying on a central control system or communication with other bodies
Solution Approach 2:
The avoidance determination unit predicts the possibility of contact between moving bodies in advance before actual collision occurs, allowing the movement control unit to proactively adjust the moving path to prevent collision rather than reacting after contact
2Extent of automation
If multiple autonomous moving bodies execute different tasks in the same environment without a single control system or intercommunication, then each body can operate independently, but overlapping avoidance paths cause significant reduction in work efficiency
Solution Approach 1:
The avoidance determination unit recognizes the type of other moving bodies and applies different avoidance rules based on local conditions - using common avoidance rules when other bodies are of the same type to coordinate avoidance paths and prevent overlapping, thereby maintaining work efficiency
Solution Approach 2:
The system changes the parameter of avoidance behavior by recognizing moving body types and selectively applying avoidance rules, transforming from uniform avoidance to adaptive avoidance that coordinates paths and prevents overlapping maneuvers

AI summary
An autonomous moving body capable of appropriately avoiding an approaching autonomous moving body and efficiently executing a given task even when the autonomous moving bodies are not controlled by a single system or without intercommunication between them and a control program for the autonomous moving body are provided. An autonomous moving body moves along a planned moving path in order to execute a given task, and includes an external sensor that recognizes another autonomous moving body given another task and an operation state thereof, an avoidance determination unit that determines, when it predicts that the autonomous moving body and the another autonomous moving body recognized by the external sensor may come into contact with each other as they approach each other, whether to avoid the another autonomous moving body, and a movement control unit that controls a movement unit based on the determination of the avoidance determination unit.
