Automated Guided Vehicle (AGV)

An AGV, Automated Guided Vehicle, is a driverless transport vehicle that moves goods along a pre-determine route in a factory or warehouse. Unlike an AMR, an AGV cannot route itself, instead it follows a fixed path defined by a physical guide on the floor or virtual guidance. AGV's are a more established technology than AMR's and have been used in manufacturing and warehousing businesses for over 50 years. They remain as one of the most reliable options for high volume, repetitive transport tasks.

Why an AGV matters

For high volume and repetitive transport tasks, like moving pallets from a production area to a dispatch area. A repeatable task between two fixed points and using the same route every time, an AGV is often one of the most cost effective solutions you can use. It will do exactly the same thing, every single time.

That predictability is the point. Because the route doesn't change, the system is simple to operate and maintain. Operators know exactly where an AGV will be and when. That makes it straightforward to integrate with production schedules and other automated systems.

AGVs aren't the right answer for everything. They need a stable layout and they don't adapt well to change. But in environments where the routes don't move and throughput is high, they can run continuously for years with minimal intervention. The ROI case is usually straightforward.

How does an AGV work?

An AGV's route is defined by a guidance system. There are several types in common use. Magnetic tape or inductive wire embedded in the floor gives the vehicle a physical path to follow. Laser guidance uses reflective targets mounted on walls or racking, with the vehicle's laser scanner triangulating its position as it moves. Natural navigation AGVs, sometimes called free-navigation, use a stored map of the facility, though they still follow pre-defined routes rather than choosing their own, like an AMR.

The vehicle picks up a task from a central control system, follows its route, and either deposits its load automatically at a fixed drop point or communicates with another system like a conveyor to hand off the goods.

Most AGV installations include traffic management software that coordinates multiple vehicles, preventing collisions at intersections and managing charging cycles. Integration with WMS or ERP systems means tasks can be triggered automatically from production or picking events, with no manual input required once the system is running.
