Autonomous driving-based automated guided vehicle system and control method thereof

Autonomous Mobile Robot System Combining Block-Based Path Planning and Real-Time Information Sharing

This technology is an autonomous mobile robot system and control method that manages autonomous vehicles based on block-defined travel paths. It prevents deadlocks by sharing location and speed data between multiple vehicles in real time, allowing for path rerouting or speed adjustments at potential collision points.

Conventional magnetic tape guidance systems incur high maintenance costs when environmental changes occur, and their centralized control systems often fail to account for the real-time status of each vehicle, limiting operational efficiency and collision prevention.

This technology structures travel paths by defining blocks using outlines, ways, surfaces, and task markers. The system controller collects operational data from each vehicle and calculates virtual travel times to determine optimal rerouting or speed adjustments. Applicable to smart factories and logistics centers, it enables flexible path changes and collision-free operations without the need for floor infrastructure modifications.
