Key Types of Automated Guided Vehicles

Not all AGVs are created equal. There are many different types of these mobile robots available, each designed to handle specific tasks and environments. Choosing the right one for your facility depends entirely on what you need to move, how heavy it is, and what your operational workflow looks like.



From simple carts that carry small parts to heavy-duty carriers for large assemblies, the various types of AGV offer unique capabilities. Let’s explore some of the most common models you’ll find in warehouses and factories today.

Automated Guided Carts and Tuggers

Automated guided carts (AGCs) are one of the simplest forms of AGVs. These vehicles are designed to transport smaller loads like totes, bins, or individual parts. They typically follow magnetic tape on the floor, making them a straightforward and cost-effective option for automating simple material handling tasks.

AGCs are often used on assembly lines to deliver components to workstations or in sorting applications. Because their paths can be reconfigured by just moving the tape, they offer a flexible solution that can adapt as your production needs change.



Similarly, tugger AGVs, also known as towing AGVs, are designed to pull a train of non-automated carts. This is an efficient way to move multiple loads at once. Tugger AGVs are popular in large facilities for delivering materials to different points along a production line or moving goods across a large warehouse floor.

Forklift AGVs and Pallet Movers

For tasks involving stacking and retrieving palletized goods, forklift AGVs are an ideal solution. These vehicles are designed to replicate the functions of a traditional forklift but without the need for a human operator. They are equipped with forks to lift and place heavy loads at various heights.

Forklift AGVs are widely used in warehouse systems for moving pallets from receiving to storage, replenishing picking locations, or loading and unloading trucks. They can handle heavy loads safely and efficiently, reducing the risk of accidents and product damage associated with manual forklifts.



Alongside them, automated pallet movers are specialized for transporting pallets at the floor level. These vehicles slide their forks under a pallet, lift it slightly, and transport it to its destination. They are perfect for repetitive, point-to-point transfers of full pallets within a warehouse or distribution center.

Unit Load AGVs and Specialized Carriers

Unit load AGVs are designed to transport individual, large-volume loads such as pallets, containers, or large racks. These vehicles often feature a platform or conveyor top that allows for the automatic transfer of goods. Their main function is to transport goods between different parts of a facility, like from the end of a production line to a storage area.

This type of automated guided vehicle is extremely common in warehousing and manufacturing. They excel at repetitive, high-volume transfers and can be integrated with other automated systems, such as conveyor belts or storage and retrieval systems, for a fully automated workflow.



For the most demanding jobs, specialized carriers are available. These heavy-duty AGVs are built to handle exceptionally large or heavy items, such as automotive chassis, large coils of metal, or aerospace components. They can be custom-designed to manage specific industrial applications and navigate tight spaces despite their size.

Advanced Navigation Technologies Used in AGVs

An AGV’s ability to move autonomously depends entirely on its navigation system. These systems range from simple, fixed-path methods to highly advanced technologies that allow for more flexibility. The choice of navigation often depends on the complexity of the environment and the tasks the AGV needs to perform.



Some of the most common methods include following physical markers like magnetic tape or wires. More sophisticated options include laser navigation and vision-based navigation, which give the AGV more freedom to operate. Let's look at how these different technologies work.

Magnetic Tape and Wired Guidance

Laser, Optical, and Vision-Based Navigation

For more flexibility, many modern AGVs use laser navigation. This technology relies on a laser scanner mounted on the vehicle that spins and emits laser beams. These beams bounce off reflectors placed at specific points around the facility, such as on walls or racking. The AGV calculates its exact position based on the angle and distance to these reflectors.

This method allows for more complex routes and doesn't require physical paths on the floor, making it a cleaner solution. It is also highly accurate and reliable, though it requires a clear line of sight to the reflectors.



Other advanced sensors enable optical and vision systems. Optical navigation involves the AGV following a painted line on the floor, while vision-based navigation uses cameras to identify features in the environment to determine its location. These vision systems are great for dynamic environments where AGVs need to adapt to slight changes.

Natural Feature and Geoguidance Systems

The most advanced navigation methods available today allow AGVs to operate without any installed infrastructure like tape or reflectors. Natural feature guidance, also known as Simultaneous Localization and Mapping (SLAM), is one such technology. AGVs using SLAM create a digital map of the facility by recognizing and recording permanent features like walls, racks, and columns.

As the vehicle moves, it continuously updates its position on this map in real time. This allows it to navigate freely and even adjust its path dynamically to avoid obstacles, making it one of the most flexible navigation methods. It's ideal for complex and changing environments.



For outdoor applications, geoguidance systems can be used. These AGVs rely on technologies like the Global Positioning System (GPS) to navigate large, open areas. While less common for indoor use due to signal limitations, it is a viable option for moving materials between buildings or across large industrial sites.

Typical Applications of AGVs in Supply Chain Operations

The use of AGVs has become widespread across the supply chain, from manufacturing floors to massive distribution facilities.
