Which of the following is the most basic Automated Storage and Retrieval System (AS/RS) used...

TheMan-on-Board AS/RSrepresents the simplest automated retrieval system where an operator rides on the storage/retrieval machine to manually select or place loads. CLT’s “Automated Systems” section identifies this as a semi-automated system that combines human control with mechanical assistance for efficiency and precision. It contrasts with fully automated AS/RS where retrieval is entirely computer-controlled. The Man-on-Board system is ideal for large or variable-sized items requiring human judgment. CLT emphasizes that even with operator presence, safety protocols—such as harnessing, emergency stops, and restricted access—must be followed. This system provides a transitional solution between manual storage and full automation, improving throughput while maintaining operator involvement.
