If that’s Monee, a worker will dispatch a robot to bring the right stack of shelves to his or her station and pick out the item. A miles-long system of conveyor belts will shuttle the item to a station where another worker will package it. It’s then sent back onto conveyor belts, where machines slap on a shipping label and eventually deliver it to one of several waiting trucks that will carry it either to a customer or another facility in Amazon’s supply chain.
