After becoming the world's largest e-commerce platform, Amazon's "UAV" program once again broke through the market's imagination of the logistics industry, the first time to complete online ordering with drones.
According to the "Wall Street Journal" news, Amazon's successful delivery this time is near Cambridge, England, carrying a total of popcorn and digital TV box products, and flew for several miles. According to reports, it took about 13 minutes for two users to place orders from the Internet and actually receive the goods. Amazon also said that they hope to start from the 5 square miles of the two users, and gradually expand to serve hundreds of people.
The report pointed out that Amazon's UAVs operate by letting buyers put a piece of cardboard on their lawns as a landing point for drones, and then the drones will automatically load and pass the personnel settings to pass through the resettlement site. The track is lifted to the open space. According to the current conditions, Amazon's drones can only be used during the daytime weather conditions. The cargo load is only about 2.27 kg (5 lbs) per time, but it can support 87% of Amazon's logistics items. Starting from the collection center, on duty on the "last road" of the arrival.
However, why did you choose to test in the UK, not the US, or even Amazon's headquarters in Seattle? Amazon pointed out that this is because the U.S. drone control standards are much looser. In addition to being able to test in farms or suburbs, drone operators are also approved by the UK government to control multiple sets of vehicles at the same time and try more complex configurations. In the United States, drones can neither fly over people, nor shrink in the floor of the building, or even fly within the eyes of the supervisor, almost impossible to experiment with Amazon's ideal delivery method.
In addition, there are other reasons for choosing to pilot in the suburbs rather than the urban areas, because the suburbs are the areas with the highest logistics costs and the lowest efficiency. The reason is that in addition to the small population of the order, the transportation route must often be extended from the urban area. In the third quarter of 2016, Amazon spent more than $3.9 billion on logistics to maintain its commitment to Prime members and reduce logistics costs, thus becoming an important part of CEO Jeff Bezos.
Initially, Bezos announced that it would switch to drones for delivery three years ago and set the target within half an hour. And although other countries or regions have successfully carried some parcels with drones, such as China’s Jingdong, which used drones to deliver goods to rural delivery workers, but like Amazon actually allows users to place orders from the website. And then directly to the drone to carry him, or for the first time in the world.
However, if you want the drone to carry cargo, especially in the big cities, there are still many tests to pass, such as preventing the culprits from shooting down the plane and stealing the goods. It is also necessary to prevent the drone from colliding with pedestrians due to malfunction. In addition, since current drones mostly use batteries to provide flight energy, under current battery technology, drones usually only fly ten miles.
Interestingly, Amazon's patents have also envisaged similar problems. It is hoped that the drones that are running out of power will have the ability to send emergency information to the driver and then "force" to the roof of the nearby car.
