Drones to replace warehouse workers

This is the first result of drone testing in Walmart’s warehouses. American supermarket chain’s airborne warehouse workers are moving down aisles, taking 30 pictures a second and scanning barcodes on boxes, doing their inventory.
Testing will continue in the next six to nine months, after which it is highly likely that drones will replace workers in one or more of Walmart’s 80 super warehouses and 190 distribution centers throughout America.
It is estimated that millions of dollars will be saved this way.
