MIT researchers use drone fleets to track warehouse inventory

Most importantly, small drones fly around safely as they read RFID tags on inventory from “tens of meters away” with a 19 cm margin of error, according to a report introducing the system. But warehouse-safe tiny UAVs aren’t big enough to carry RFID readers that reach such a range — so the MIT researchers simply made the drones relay signals from standard readers to items and back. That means
