Amazon revealed the latest prototype of drones it will deploy as part of its Prime Air service using the unmanned aerial devices to deliver packages in under 30 minutes.
According to details released Sunday by the online retailing giant, Amazon says the drones weigh 55 pounds and can carry packages weighing up to 5 pounds.
The drones fly under 400 feet and use "sense and avoid" technology to dodge potential obstacles en route to its delivery destination.
In March, the Federal Aviation Administration granted Amazon approval to fly drones for research into the Prime Air service after first revealing plans to work with drones for deliveries two years ago.
