DoorDash 正在为其日益自动化的配送车队增添新的成员：一款由内部设计并制造的无人机。
DoorDash is adding another vehicle to its increasingly automated delivery fleet: a drone designed and built in-house.
为何重要：DoorDash 正在构建一个庞大的多模式配送网络——涵盖人类配送员、机器人和无人机——并利用其软件为每笔订单选择最合适的配送方式。
Why it matters: DoorDash is building a sprawling multimodal delivery network — humans, robots and drones — and using its software to decide which is best for each order.
新闻驱动：DoorDash 于周二发布了为其内部无人机配送服务“DoorDash Air”开发的飞行器。该服务将在北加州启动试点配送，合作餐厅包括 Chipotle、Popeyes 和 Momo N Curry。
Driving the news: DoorDash on Tuesday unveiled the aircraft developed for DoorDash Air, its in-house drone delivery service, which will begin pilot deliveries in Northern California with restaurants including Chipotle, Popeyes and Momo N Curry.
这款六旋翼无人机是围绕 DoorDash 自身的订单数据设计的，包括典型餐厅订单的重量和配送距离。
The six-propeller drone was designed around DoorDash's own order data, including how much typical restaurant orders weigh and how far they travel.
深入细节：DoorDash 表示，其美国餐厅订单中约有 80% 体积小且重量轻，适合该飞行器承载，但距离和天气等因素将进一步限制符合条件的订单范围。
Zoom in: DoorDash says about 80% of its U.S. restaurant orders are small and light enough for the aircraft to carry, although factors including distance and weather will further limit which orders qualify.
公司称，在初步测试中，从餐厅到客户的飞行时间平均不到五分钟。
itial tests, flights from restaurants to customers averaged less than five minutes, the company says.
DoorDash Air 负责人 Harrison Shih 表示：“我们不是先造出一架无人机，然后问它能装什么。我们是从人们点餐的内容以及本地企业的实际运营方式出发，然后在此基础上构建了整个系统。”
"We didn't start with a drone and ask what would fit. We started with what people order and how local businesses actually operate, then built the entire system from there," said Harrison Shih, head of DoorDash Air.
Shih 告诉 Axios，他认为无人机配送的速度将鼓励人们更频繁地使用 DoorDash。
Shih tells Axios he thinks speed of drone delivery will encourage people to use DoorDash more often.
他说，例如，如果你漏点了牧场沙拉酱或薯条，无人机可以几乎立即将其送达。
If you're missing a side of ranch dressing, or french fries, for example, the drone can bring it almost instantly, he said.
宏观视角：DoorDash 目前已通过合作伙伴（包括 Alphabet 旗下的 Wing 和 Flytrex）提供无人机配送服务，这些合作将在 DoorDash Air 推出后继续并行。
Zoom out: DoorDash already offers drone delivery through partners including Alphabet's Wing and Flytrex, and those efforts will continue alongside DoorDash Air.
这与 DoorDash 去年发布其自研地面配送机器人 Dot 的情况类似，旨在补充其合作伙伴 Serve Robotics 和 Coco Robotics 的人行道机器人。
It's similar to when DoorDash last year unveiled Dot, its own ground delivery robot, to complement sidewalk bots from its partners Serve Robotics and Coco Robotics.
连接这一切的是 DoorDash 的自主配送平台，该平台会权衡距离、重量、天气和交通等因素，以决定订单应由人类配送员、机器人还是无人机完成。
The connective tissue is DoorDash's Autonomous Delivery Platform, which weighs factors including distance, weight, weather and traffic to determine whether an order should go by human Dasher, robot or drone.
现状：DoorDash表示，最棘手的问题未必是让无人机飞起来，而是如何将订单从繁忙的餐厅厨房无缝送入空中，再送到顾客家门口。
State of play: DoorDash says the toughest problem isn't necessarily flying the drone — it's getting orders seamlessly from busy restaurant kitchens into the air and then onto customers' doorsteps.
该公司设计了装载系统、包装方案以及基于绞盘的取送系统，旨在尽量减少餐厅员工的额外工作。
The company designed loading systems, packaging and a winch-based pickup and drop-off system aimed at minimizing extra work for restaurant employees.
核心要点：DoorDash押注的不是某一种机器人或无人机，而是未来的配送网络将把它们全部用上——并且由DoorDash来决定派哪一个把你的晚餐送上门。
The bottom line: DoorDash's bet isn't on any single robot or drone. It's that the delivery network of the future will use all of them — and DoorDash will decide which one is assigned to bring your dinner.
