What is an Automated Storage and Retrieval System (ASRS)?

An ASRS is a warehouse automation system that uses robotic equipment and software to automatically store and retrieve inventory efficiently.

What are the benefits of ASRS?

ASRS systems improve storage capacity, reduce labour costs, increase inventory accuracy, and improve warehouse efficiency.

What industries use ASRS systems?

ASRS systems are used in warehousing, manufacturing, retail, logistics, automotive, and pharmaceutical industries.

How do ASRS systems improve warehouse efficiency?

ASRS systems automate storage and retrieval processes, reducing manual handling, improving speed, and increasing inventory accuracy.

What is an ASRS (automated storage and retrieval system)?

An ASRS is a combination of equipment and controls that automatically stores and retrieves loads from defined storage locations with speed and precision. Common types include mini-load and unit-load cranes, shuttle systems and vertical lift modules, all removing manual handling and maximising storage density.

What does ASRS stand for?

ASRS stands for Automated Storage and Retrieval System. It describes automated warehouse systems that store and retrieve goods without manual forklifts or picking, typically using cranes, shuttles or robots working with high-density racking.

How much does an ASRS cost?

An ASRS is a significant capital investment that varies widely with throughput, height, load type and technology, from smaller shuttle or VLM installations to large unit-load crane systems. Most UK ASRS projects are justified on labour savings, storage density and accuracy, with payback typically inside a few years.

What are the main types of ASRS?

The main types are unit-load ASRS (full pallets), mini-load ASRS (totes and cartons), shuttle-based systems, carousels and vertical lift modules (VLMs). The right choice depends on load size, throughput and how much storage density and speed you need.

What is the difference between an ASRS and conveyor system?

A conveyor moves goods along a path; an ASRS stores and retrieves them from dense racking. They are complementary: conveyors transport loads to and from the ASRS, which handles the high-density storage and automated put-away and picking.

What Is an ASRS System?

An Automated Storage and Retrieval System (ASRS) is a combination of computer-controlled machines, high-density racking and warehouse software that automatically places goods into storage and retrieves them on demand, without manual handling. A typical ASRS brings together storage and retrieval machines such as cranes or shuttles, dense racking or shelving, in-feed and out-feed conveyors, and control software that directs every movement. By removing the need for operators to walk to and from storage locations, an ASRS increases storage density, speeds up order fulfilment and improves accuracy across warehouse and manufacturing operations. It is one of several warehouse storage systems MotionTech designs and integrates for UK operations.

How ASRS Systems Work

An ASRS works by storing and retrieving goods automatically under the control of warehouse software. When stock arrives, the system assigns it an optimal location and a crane, shuttle or robot moves it into the racking. When an order is placed, the software directs the same equipment to retrieve the required item and deliver it to a pick station or out-feed conveyor. Because the system knows exactly where every item is held, it sequences movements for maximum throughput and feeds goods to operators on a goods-to-person basis, rather than sending people to search the warehouse. Integration with your warehouse management or ERP system keeps stock records accurate in real time.

Types of ASRS Systems

ASRS-warehouse-automation-solution

Unit Load ASRS

Unit load ASRS systems are designed to handle palletised goods and heavy loads. These systems are ideal for manufacturing facilities, pallet warehouses, and high-volume storage operations.

Mini Load ASRS

Mini load systems are designed for handling smaller items stored in bins, trays, or totes. They are commonly used in e-commerce fulfilment and distribution centres.

Shuttle-Based ASRS Systems

Shuttle systems use robotic shuttles to transport goods quickly within storage racks, providing high-density storage and fast retrieval speeds.

Vertical Lift Modules (VLMs)

Vertical lift modules use vertical storage columns and automated lifts to store and retrieve products efficiently, maximising vertical storage capacity.

Goods-to-Person ASRS

Goods-to-person (GTP) systems bring stored items directly to the operator at a pick station, cutting walking time and improving picking accuracy and throughput across the warehouse.

ASRS Racking Systems

An ASRS racking system is the structure that holds the stored pallets, totes or cartons and guides the machines serving it. Depending on the system, the racking is designed around cranes, shuttles or carriers, with tighter tolerances than conventional static racking so the machines can travel and place loads reliably.

Racking can be built tall and dense, using the height of the building rather than floor space, and sized for pallets, totes or cartons. Pallet shuttle racking stores pallets in deep lanes served by shuttle vehicles, while miniload systems use crane-served racking for totes and cartons.

The right racking depends on the load, the throughput you need, the building height and any planned expansion. MotionTech designs ASRS solutions that combine racking, machines and warehouse software. See also warehouse storage systems and automated warehouses.

Robots increasingly work alongside automated storage, from picking to palletising. Our guide to warehouse robotics explains how.

How to Choose the Right ASRS System

Choosing the right automated storage and retrieval system depends on your products, throughput and building. The key factors to weigh are:

Load type and size: palletised goods suit unit-load or pallet shuttle ASRS, while smaller cartons, totes and parts suit mini-load, shuttle or goods-to-person systems.
Throughput requirements: high-volume, time-critical operations need faster shuttle or goods-to-person technology, while steadier operations may be well served by crane-based ASRS.
Available space and height: ASRS is most cost-effective where you can build upward, so ceiling height and footprint shape the design.
SKU range and order profile: a wide, fast-moving SKU base favours goods-to-person picking, while slower-moving stock suits high-density storage.
Integration and software: the ASRS must connect to your warehouse management or ERP system to deliver its full benefit.

Getting these decisions right at the design stage is what separates a system that pays back quickly from one that becomes a bottleneck. Our team assesses your operation and specifies the right ASRS technology before anything is built.

ASRS Cost and Return on Investment

The cost of an automated storage and retrieval system varies widely with scale, technology and throughput, so it is best understood through payback rather than headline price. A typical ASRS business case weighs the capital investment against:

Reduced labour as goods-to-person and automated retrieval cut walking and manual handling.
Reclaimed floor space as high-density storage holds more in a smaller footprint, often avoiding a costly building expansion.
Higher accuracy and throughput that lift service levels and reduce picking errors.
Lower running costs from modern, energy-efficient drive systems.

Most operations model the return over the equipment working life, and a well-designed ASRS typically delivers a clear payback while future-proofing the operation against rising labour costs and demand peaks. We help build a defensible ASRS business case before you invest.
