Automated storage and retrieval systems (AS/RS) use computer-controlled mechanisms to store and retrieve items from defined storage locations without manual intervention. Here’s how the process works:

1. Item Storage: Products are loaded into trays, bins, or carriers and assigned a unique storage location by the system’s inventory management software. The automated mechanism places each item in its optimal location based on size, weight, and retrieval frequency.
2. Retrieval Request: An operator enters a part number, SKU, or barcode at the access window. The system’s controller identifies the exact storage location and initiates retrieval.
3. Automated Delivery: The storage mechanism — whether a vertical lift module, rotating carousel, or robotic shuttle — brings the requested item directly to the operator’s ergonomic access point in seconds.
4. Pick Confirmation: Pick-to-light indicators or software prompts guide the operator to the correct item and quantity. The system updates inventory counts in real time.

This goods-to-person approach eliminates walking, searching, and climbing — reducing pick times by up to 70% compared to traditional shelving while virtually eliminating pick errors.
