Tip of the Spear Technology: Cleveron

Cleveron manufactures a self-service pickup point for click-and-collect consumer goods orders that is designed to efficiently automate high-volume storing, delivering and even returning of shipped parcels. The unit is modular in height (3.1 to 4.75 meters) and width (3.7 to 13.7 meters), expandable from a 266-tray minimum to a 3,600-tray maximum. 

Walmart has already tested the concept.
