Automated Guided Vehicles (AGVs) are autonomous, driverless machines revolutionizing material handling across diverse industries. These vehicles autonomously transport goods within facilities such as warehouses, factories, and hospitals. Faced with increasing global labor shortages, businesses are adopting AGVs as a practical solution. According to Korn Ferry, the talent shortage could reach 85 million unfilled positions by 2030, potentially costing businesses $8.5 trillion in revenue loss.
Instead of replacing jobs, automation is now seen as a way to fill positions that can’t be filled by humans. AGVs, along with other automated technologies, are becoming essential for maintaining production levels in the face of labor market challenges.
Understanding the Basics of AGV Operation
In simple terms, an AGV is a vehicle equipped with an internal navigation system, enabling it to navigate its environment and execute assigned tasks. Navigation systems range from sensor-based reflector tape reading to sophisticated laser navigation. AGVs utilize distance calculations and turning angles to accurately pinpoint their location within a pre-mapped facility.
Furthermore, AGVs require instructions regarding destinations, material pick-up points, and drop-off locations. Central control systems, powered by specialized software, manage these tasks by assessing requests for goods and assigning the appropriate AGV to each load.
The integration of driverless vehicles and intelligent fleet control software automates repetitive material handling processes, boosting efficiency and empowering the human workforce to focus on more demanding activities.

Exploring Different AGV Applications
The application of AGVs varies significantly depending on the industry and specific requirements.
Smaller AGVs are commonly employed in hospitals to deliver medications, equipment, and other essential supplies. Conversely, larger AGVs are utilized in factories and warehouses to transport palletized goods weighing thousands of kilograms, efficiently transferring goods between inbound and outbound areas and stacking materials in racks up to several meters high.
Regardless of the specific material movement needs, there is an AGV solution available to address almost any industrial requirement.
AGVs vs. Driver-Operated Forklifts: A Comparative Analysis
Advantages of AGVs
The primary objective of implementing AGVs is to alleviate routine tasks from the human workforce, freeing up skilled drivers for more complex responsibilities.
According to Kari Johansson, Solutions Management Director at Mitsubishi Logisnext Europe, the shortage of forklift drivers in North America and Western Europe is a major driver for automation. AGVs can reduce repetitive tasks, allowing human drivers to focus on more advanced jobs.
Another significant advantage of AGVs is enhanced safety. These vehicles adhere to stringent safety standards and incorporate hardware and software solutions to minimize accidents. Advanced sensors detect obstructions, while control software monitors AGV traffic, enabling vehicles to slow down or stop safely.

AGVs can also operate continuously, offering a considerable advantage for organizations facing heavy workloads. Smart battery management systems automatically direct vehicles to charging stations when idle or when battery levels are low, further reducing the burden on employees.
Advantages of Driver-Operated Forklifts
Despite the numerous benefits of AGVs, certain material handling tasks still necessitate human intervention. For instance, oversized or irregularly shaped loads are better managed by human operators who can adapt to unforeseen challenges.
Human problem-solving skills are also crucial when unexpected situations arise, such as maintenance or obstacles that block an AGV’s route. In such scenarios, driver-operated forklifts can handle these situations until the blockage is cleared or AGVs are rerouted.
Facilities with limited space and tight corners may also benefit more from driver-operated forklifts. However, AGVs like the Rocla ACT are designed to operate effectively in confined areas.
In conclusion, AGVs are not intended to replace the human workforce entirely. Instead, they should be integrated into a hybrid system where AGVs handle repetitive tasks, allowing humans to focus on more intricate and engaging jobs.
AGVs vs. AMRs: Key Differences
Automated Guided Vehicles (AGVs) and Automated Mobile Robots (AMRs) share similarities but differ primarily in their navigation methods.
AMRs use onboard navigation and autonomous decision-making to map their surroundings, making them suitable for simpler applications with minimal route variations.
AGVs, on the other hand, utilize sophisticated fleet management software to track the real-time location of each vehicle. This information enables the software to assign the most appropriate vehicle and optimize the route for efficient load movement.
Understanding the Automated Guided Vehicle System

An AGV system comprises AGVs and the fleet management software that orchestrates their movement.
This software determines task assignments and calculates the most efficient routes, dynamically adjusting routes as new tasks arise. Without this intelligent software, AGVs cannot function effectively. Logisnext’s FleetController software, for example, employs AI-based algorithms to optimize traffic and material flow.
According to Johansson, fleet management software can be compared to real-time traffic management systems that reroute vehicles to avoid traffic jams.
The system monitors the position of each AGV within the facility, enabling it to anticipate and mitigate potential traffic congestion by rerouting vehicles. It also plans delivery sequences to meet deadlines, ensuring seamless material flow throughout the facility.
The level of automation within the AGV system is customizable, allowing businesses to create a balanced mix of human and automated vehicles tailored to their unique facility requirements.
Addressing challenges such as labor shortages requires innovative solutions. AGVs, supported by advanced AGV systems, enable businesses to achieve more with fewer resources and empower their human workforce to focus on more complex and value-added activities.
