System and design of a compact and heavy-payload AGV system for flexible production line

This paper presents a new Automatic Guided Vehicle (AGV) system, in which unique compact and heavy-payload under-cart design, high precision hybrid-mode stopping, modularized software and distributed AGV-caller system, are integrated to provide a reliable and worker-friendly AGV system for the flexible production Une. Besides, the results of a series of in-field tests validate the payload and precise stopping performance of our AGV system.
