WHAT IS an automated storage and retrieval system (Asrs)?
An Automated Storage and Retrieval System (ASRS) is a computer-controlled system designed to automatically place and retrieve goods from defined storage locations.
These systems maximise vertical and horizontal space, improve inventory accuracy, and enable high-density storage in warehouses and distribution centres.
Also known as:
- Automated warehouse system
- Automated storage system
- Robotic storage system

HOW DOES an asrs WORK?
ASRS solutions use shuttles, cranes, or robotics to move goods into and out of storage. Controlled by a Warehouse Control System (WCS) or Warehouse Management System (WMS), they ensure precise, automated movement of inventory.
Typical ASRS technologies include:
- Unit-load systems – large cranes handling pallets or heavy items.
- Mini-load systems – smaller shuttles or cranes handling totes and cartons.
- Shuttle systems – high-speed carriers moving goods across multiple levels.
- Carousel systems – horizontal or vertical carousels rotating goods to pick stations.
BENEFITS OF an asrs
- Space efficiency: Maximises cubic storage capacity in warehouses.
- Speed: Accelerates picking and replenishment cycles.
- Accuracy: Reduces human error in storage and retrieval.
- Labour savings: Minimises reliance on manual handling.
- Safety: Reduces risks associated with forklifts and manual lifting.
