In another step toward automating its workforce and services, Walmart has applied to patent a system that would let shoppers with questions summon a drone for answers and guidance.
The retail giant earlier this month showed off a pilot project in Bay Area stores that uses robots to scan inventory on shelves.

“The user can request price verification and/or navigation assistance, for example, through a user interface of the mobile electronic device,” the patent application said, adding that a device loaned temporarily to the customer could be used to call the drone.
The drone could scan barcodes, and provide a display or even a machine-spoken answer. A shopper would not even have to seek out the item in the first place: the drone could be summoned, then sent to go find an item and check for the most up-to-date price, before flying back and providing the information to the customer.
