pick and pass

— Tiered facilities lend themselves to a number of picking schemes — and the automation of warehousing operations can serve to optimize those operations. One is called “multi-level pick and pass,” in which specific robots are assigned to each floor in the facility. The robotic solution clusters tasks on each floor for density and efficiency. When all of the picks on one level are complete, the robot travels to a drop-off station where the container is transported by conveyor to the level below.
