Automated Storage and Retrieval System (AS/RS) 

An automated storage system, off-limits to humans, where goods are placed and retrieved from storage in a centrally-run computer-operated system. An AS/RS system can use automated guided vehicles (AGVs) or conveyor systems. Efficient for high-volume items but is CapEx-intensive and susceptible to single-point system failure. AS/RS solutions were first developed in the 1960s.
