 According to Invia Robotics (2019), the first automated guided vehicle (AGV) system, which eventually led to AGV forklifts, was introduced in the 1950s by Barrett Electronics of Northbrook, Illinois. The website also states that the initial AGV forklift was a simple towing machine that followed a wire laid in the floor, used primarily in warehouses and factories to transport materials. Nowadays, many types of AGVs have been developed, some utilizing simple sensors which track reflector tapes and others which use advanced laser-guided sensors (Mansfield, 2024). Most popularly used are the AGVs with laser navigation; this system uses a combination of a laser scanner on the AGV and multiple reflective targets placed throughout the facility. Laser strobes bounce off the reflectors which are detected by the AGV’s receivers and then utilized as inputs for its control algorithm, which then guides the AGV’s movement within the warehouse (Robopac USA, 2022). AGV forklifts have been the solution to many businesses intending to overcome labor shortages or cut costs, as these systems have proven to be cheaper than driver-operated forklifts (Goodwin, 2022). The advancements in AI and robotics have allowed for the development of AGV technologies, such as AGV forklifts, which reduce manpower costs in manufacturing settings, increase productivity, and also minimize inventory damages and accidents.

Automated Guided Vehicle (AGV) forklifts have demonstrated significant potential for reducing labor costs and enhancing productivity in various industrial settings. Traditional forklifts require skilled operators, and hiring and retaining such workers has become increasingly challenging due to a shrinking labor force and rising wages (Goodwin, 2022). By contrast, AGVs can operate continuously without needing breaks and can maintain consistent and predictable outputs. Additionally, AGVs eliminate the costs associated with training workers to operate manually-operated forklifts. Some systems, like Robopac USA’s laser-guided vehicles (LGVs), have integrated smart battery management systems that automatically guide the AGV to charging stations when power is low, ensuring minimal disruption to operations. This feature supports continuous operation in facilities with 24/7 requirements, thereby improving uptime and efficiency (Robopac USA, n.d.). These factors contribute to a reduction in labor costs and translate to increased output and productivity, making AGVs an attractive option for businesses aiming to optimize their operations.

AGV forklifts are equipped with advanced technologies such as laser navigation and a comprehensive sensor technology, which makes it more efficient and safer than a manually operated forklift. The most basic setup for an AGV forklift utilizes a series of reflective targets throughout the warehouse. These targets are detected by the laser scanner mounted on the AGV forklift, and the data is used by the control system to determine the vehicle's location and the next course of action. This setup ensures flexibility without being hindered by the quality of the floor surface, as the reflective targets and sensors are located above the floor (Robopac USA, 2022). In addition, AGV forklifts are equipped with high-quality proximity sensors that provide a 360-degree field of view, enabling them to slow down or stop within milliseconds upon detecting a person or an obstacle (Mitsubishi Logisnext, n.d.). With advancements in robotics and artificial intelligence, AGV forklifts continue to evolve, becoming not only faster and more efficient but also safer, as they integrate these cutting-edge technologies into their operations.

However, despite the clear benefits of AGV forklifts, there are notable drawbacks, particularly regarding their high initial costs. Depending on the model and capabilities, the price of an AGV can range from $30,000 to over $200,000 (Mobile Robot Directory, n.d.). This high initial cost can be prohibitive for smaller businesses, making it challenging for them to justify the investment without substantial financial resources or external funding. Moreover, the implementation of AGVs often requires reconfiguring the warehouse layout, which involves additional costs and operational disruptions. For AGVs to function effectively, a facility’s floor plan typically needs to be standardized, as AGVs rely on consistent environments to execute repetitive tasks. This requirement can make the operations within a warehouse less flexible, limiting the adaptability of the facility to accommodate changes in workflows or product types (AGV Network, n.d.).

Furthermore, AGVs may struggle in environments that are not well-suited to their rigid navigation systems. In facilities where product types, inventory arrangements, or workflows change frequently, AGVs can be less adaptable compared to human-operated equipment. This is because AGVs follow predefined paths and often require human intervention when encountering unexpected obstacles. As a result, AGVs are unsuitable for non-repetitive tasks or areas where routes change regularly, reducing their efficiency and creating the need for frequent manual adjustments (Invia Robotics, 2024). While AGVs are well-suited for repetitive, high-volume tasks, their lack of flexibility in dynamic environments can be a significant limitation, making them less appealing for businesses that require versatility in their operations.

In conclusion, AGV forklifts are able to reduce the manpower woes and costs for many companies. They are often more efficient and safer than a manually operated forklift. However, smaller to medium sized companies may find that these novel technologies to be far too expensive in terms of their initial cost and warehouse space constraints. In spite of this, the advantages of AGV forklifts far outweigh its disadvantages. And as proven in the past, AGVs continue to improve and are only bound to become more affordable and more efficient as technology in robotics and sensors advance, allowing even smaller companies to utilize AGV forklifts.
