Although the patent remains pending, the details are clear: Amazon is serious about drones.
CNN reports that Amazon is aiming not only to deliver products via drone to your house, but to your person. The patent outlines a service called "Bring It To Me" in which the user provides location information and the drone can be sent right to them. You don't even have to stay in the same place - the drone will track your location through your phone and deliver it to wherever you may be. Boat deliveries and car deliveries will also be standard practice.
The drone will also modify and plan it's route to avoid other air traffic (like other drones), major highways, and animals/humans it may disturb. The units will use infrared light, cameras, and sensors to avoid all of these hazards.
Amazon received an experimental airworthiness certificate from the FAA to test delivery drones, which allows the online-retail giant to test prototypes. According to FAA rules, drones can weigh up to 55 pounds, can travel up to 100 miles per hour, and can fly up to 400 miles per hour. Amazon "Prime Air" has been in (hypothetical) business since 2013.
Skeptics are likely to call on the constant location services needed for drone delivery. Just don't try to get a package delivered while you're driving on the highway!
