• Forklift AGVs: Equipped with forks, these AGVs can lift and move pallets, allowing for more versatile operations. They are particularly useful in environments where vertical storage is utilized, as they can navigate tight spaces while performing lifting tasks.

How AGVs Work

AGVs operate using a combination of hardware and software. The hardware includes the vehicle itself, sensors for navigation, and communication systems for coordinating with other machines and systems. The software component involves algorithms that enable path planning, obstacle detection, and task scheduling. This integration of hardware and software is what allows AGVs to function autonomously and efficiently.

Navigation is a critical aspect of AGV functionality. Most AGVs use one of three primary navigation methods:

• Laser navigation: This method employs lasers to create a map of the environment, allowing the AGV to determine its position and navigate accordingly. The precision of laser navigation makes it suitable for environments where accuracy is paramount.
• Magnetic tape: Some AGVs follow a magnetic tape laid on the floor, which guides them along a predetermined path. This method is often simpler to implement but may lack the flexibility of more advanced navigation systems.
• Vision-based navigation: Using cameras and image processing, these AGVs can identify landmarks and navigate dynamically. This technology allows for greater adaptability in changing environments, as the AGVs can recognize and respond to obstacles or changes in layout.

Moreover, the efficiency of AGVs is enhanced by their ability to communicate with other systems, such as warehouse management systems (WMS) and enterprise resource planning (ERP) software. This connectivity enables real-time data exchange, allowing AGVs to receive updated instructions and optimize their operations based on current inventory levels and order priorities. As a result, AGVs not only streamline material handling but also contribute to overall operational transparency and responsiveness in supply chain processes.
