Dynamic Route Adjustment for Autonomous Mobile Robots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional operation management systems for autonomous mobile robots require suspension or rerouting when issues arise, leading to operational disruptions due to insufficient administrative resources, as they are designed to recognize problems on predefined routes only.
Innovation Solution
An operation management system that allows autonomous mobile robots to dynamically adjust their routes based on real-time environmental data from sensors, enabling continuous operation by re-routing affected robots and utilizing multiple robots to alleviate travel performance issues and prevent malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the conventional operation management system recognizes problems on predefined routes only, then the system can maintain simple route management, but the autonomous mobile robots cannot operate continuously when problems occur
Solution Approach 1:
The patent transforms the static predefined route management into a dynamic route adjustment system. When a robot detects a problem environment, the operation management unit dynamically generates alternative routes based on real-time sensor data and robot positions, enabling continuous operation without requiring complex manual intervention or rigid predefined alternatives.
Solution Approach 2:
The system enables autonomous mobile robots to self-report their environmental status through sensors, and the operation management unit automatically processes this information to generate route adjustments. This self-service mechanism eliminates the need for continuous human monitoring and manual route reconfiguration, maintaining reliability while managing complexity through automation.
2Ease of operation
If the system administrator manually solves problems on predefined routes, then the system can maintain simple problem recognition, but the autonomous mobile robots must be suspended or require separate route setting
Solution Approach 1:
The patent implements a feedback loop where sensors on autonomous mobile robots continuously monitor the environment and report status to the operation management unit. This real-time feedback enables automatic detection of problem environments, triggering automated route adjustments that maintain productivity while keeping the interface simple for administrators.
Solution Approach 2:
The system performs preliminary actions by pre-establishing the operational framework and sensor monitoring capabilities before problems occur. When issues arise, the pre-configured automatic response mechanisms immediately generate alternative routes, eliminating the need for manual intervention and maintaining continuous operation without sacrificing ease of initial setup.
3Area of stationary object
If multiple autonomous mobile robots operate in the same region, then the system can improve coverage and guidance capability, but the system complexity increases due to multiple robot coordination
Solution Approach 1:
The patent creates a universal operation management unit that handles multiple robots through a common standardized interface. Each robot operates autonomously with identical sensor and communication capabilities, allowing the system to scale coverage area without proportionally increasing coordination complexity. The same route adjustment logic applies universally to all robots regardless of their specific tasks or locations.

AI summary
An operation management system includes: a plurality of robots; and an operation management unit server configured to manage an operation route in a predetermined region. Each robot has a sensor that recognizes a surrounding environment. When the sensor of a first robot recognizes a predetermined surrounding environment, the server refers to a position of the surrounding environment and sets an operation route of a second robot.
