Automated Guided Vehicles (AGVs)
These are also known as mobile robots. Unlike robotic arms, which consist of joints and links attached to a base, mobile robots are not confined to a fixed range of movement. They are self-contained and can navigate along surfaces, spaces, or lines. Often, mobile robots are combined with robotic arms, providing a platform for the arms to perform versatile functions such as scanning, remote handling, and probing.
The design of automated guided vehicles is very complex as compared to that of robotic arms. Besides the issues of locomotion, there are many other aspects to consider such as path planning, perception, localization, and motion control. Automated guided vehicles are classified into the following categories.
Autonomous AGVs
This robust, flexible, and accurate automation solution is designed to meet the needs of producers and operators of automated guided vehicles. Its advantages include flexibility and scalability.
Forklift AGVs
These are automated guided vehicle navigation systems integrated into forklifts. They are primarily used for stacking pallets at various heights and are well-suited for ground-level pallet lifting.
Automatic guided vehicles (AGVs) are load carriers that navigate a facility’s floor autonomously, without a driver or operator onboard. These computer-controlled, wheel-based systems use both software-based and sensor-based guidance systems to control their movement. AGVs ensure safe load transportation by following predetermined routes, accelerating and decelerating accurately, and using bumpers to automatically detect obstacles. They are commonly used for transporting raw materials, work-in-progress, and finished items in robotics manufacturing production lines, as well as for storage and retrieval to support picking in distribution and warehousing applications.
Underride AGVs
These are also known as automated guided carts. They operate by driving underneath a basket and slightly lifting it, performing their tasks at the destination without any intervention. Primarily used in hospitals, they are employed for delivering medical supplies, food, and linens.
Towing AGVs
These are also known as tagger-guided vehicles. They are used to pull undriven trailers or carriers and can handle multiple loads more efficiently compared to underride AGVs and forklift AGVs, as they do not need to perform additional lifting. However, towing automated guided vehicles are designed exclusively for transport and cannot position the loads at their designated locations.
Unit Load AGVs
These automated vehicles are designed for transporting palletized or unitized goods without lifting the load from the ground. Lifting is handled by other equipment, such as forklifts, conveyors, and cranes.
Assembly AGVs
These are also known as tunneling automated guided vehicles. Their primary use is transporting goods to an assembly point. They are highly maneuverable, making navigation straightforward as they can easily orient themselves and fit into assembly stations.

Chapter 7: What are the applications and benefits of warehouse automation?
This chapter will explore the applications and advantages of warehouse automation.
Applications of Warehouse Automation
Warehouse automation has a wide range of applications across various industries. It is employed in robotics for manufacturing in sectors such as aerospace, automotive, and agriculture, as well as in medical facilities.
Some practical applications of warehouse automation across different industries include:
- Barcode scanning - Automated warehouses use barcode scanning and labels to optimize warehouse operations and dominate online retail
- Picking automation with goods-to-person (G2P) systems – These systems make use of autonomous robots to carry packages and products that are loaded on pallets to warehouse employees for order fulfillment.
- Back office automation - Warehouse management systems that have digital automation features can make use of back office operations.
- Inventory automation with retrieval systems - These systems are capable of transferring as many pallets as over five hundred in an hour to their respective dispatch areas.
Benefits of Warehouse Automation
The advantages and benefits of an automated warehouse system are numerous. Modern warehouse technologies are more scalable and user-friendly compared to older automation solutions such as conveyors.
Conveyors are fixed and bulky, whereas operators can rent additional robots to handle increased demand during peak periods and return them when demand decreases. Collaborative mobile robots require no infrastructure changes. Other benefits of warehouse automation include increased productivity and reduced worker strain and fatigue.
Automated warehouses also lead to fewer injuries. Additional advantages include reduced operating costs, increased accuracy, and fewer shipping mistakes. Automation optimizes space by making use of vertical storage locations that are difficult for humans to access.
The use of drones and certain retrieval systems facilitates access to higher storage locations. Investing in an automated warehouse proves to be a sound financial decision due to significant cost savings from reduced errors, fewer injuries, and increased productivity.
Conclusion:
Warehouse automation is the process of using automated technology to take the place of repetitive operations. The major objective is to eliminate time-consuming and labor-intensive tasks. As a result, employees are better able to concentrate on crucial jobs like quality control. However, warehouse automation refers to the use of software to replace tasks that are now done manually and does not always entail the employment of robots or other devices. Over time, the use of automated warehouses has immensely benefited civilization. Robotics manufacturing is used by the automotive industry and retail, which are some of the sectors that use this emerging technology. They have seen significant changes with the advent of artificial intelligence that has dramatically increased worker productivity and efficiency.
