Is it a bird? Is it a plane? No, it's your online shopping! Imagine a world where your shopping was dropped off on your doorstep by a delivery (投递) drone (无人机). Well, many companies are working to make this idea a reality. Among them, Amazon and UPS are just some of the front runners in the race to have the first ever business drone delivery service.
Pros:
①Fast. Delivery drones can cut down the time of delivery to just 30 minutes.
②Environmentally friendly. Companies like UPS have started that the use of drones would cut down on waste gas (气体).
③Cheap. Though exact prices for drone delivery aren't known, companies such as Amazon suggest deliveries could be as cheap as $1.
④Emergencies. Drones can fly straight to areas they're needed without using any roads.
From Dispatch (分派) to Doorstep:
Usually products available for drone delivery will be stored somewhere nearby. Customers will choose these products through shopping apps or websites. The suggested weight to be carried is no more than 2.3 kilograms. Once the products are put into the drone, it will take off from the dispatch center. It will fly below 120m and avoid any "No Fly Zones" like airports for safety reasons. Before landing, a pad will be placed in the customer's garden for the drone's landing. After the drone puts down its product, it will rise to return to the dispatch center. So a drone delivery could one day be just a touch of an app with your finger.
Cons:
①Weather like strong winds, lightning storms and heavy rainfall may influence deliveries.
②Dispatch centers will have to be built within certain distance.
③Drones might be unable to land safely in high-rise buildings.
④Something will have to be done to make sure about the safety of the products and of people walking below.
The future of flying transportation
Though the delivery drone service is alive with new technology, we are a long way from seeing them through the air. There are still many difficulties such as flight law making. It's said that by 2021 we might see the beginning of drone delivery systems in action.
