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

Autonomous Mobile Robot System Integrating Path Block Segmentation and Speed Control

This technology controls the navigation of autonomous mobile robots based on path information defined in blocks. It defines surfaces and task markers—including outlines, ways, and speed data—within each path block to perform obstacle detection, collision avoidance, and speed regulation.

Conventional magnetic tape guidance systems incur high reinstallation costs when factory layouts change. Furthermore, they struggle with efficient speed control and flexible task execution because central control systems cannot account for the real-time status of individual robots.

This technology segments movement paths into blocks, allowing users to configure routes and tasks via an interface. The central system aggregates status information from individual robots to calculate speed adjustments or detours in real-time based on estimated arrival times. Applicable to automated transport in factories and warehouses, it enables flexible responses to facility changes and continuous improvements in operational efficiency.

Key Features:

• A transport vehicle drive unit equipped with a sensor module and a drive motor for the vehicle body
• A transport vehicle control unit connected to the sensor module and drive unit to regulate the operation of the drive motor
• A configuration that sets and inputs movement paths in block units containing outlines, ways, surfaces, and task markers
• A system control unit that aggregates operational data from each vehicle to manage speed or detours based on estimated arrival times
