What could a drone do in a cafeteria?

一架无人机在自助餐厅里可以做什么？

The world's first drone cafe, which has just opened its doors at Eindhoven University of Technology in the Netherlands, employs a robotic fleet known as Blue Jay to deliver the drinks.

全球首家无人机咖啡厅日前刚在荷兰埃因霍芬理工大学开业，该咖啡厅雇佣了一个名为"蓝色杰伊"的机器人团队传送饮品。

The drone looks like a small white flying saucer with shiny eyes. It buzzs over to a customer, take orders by way of camera sensors¹ (you can choose from one of four drinks), and your selection is then communicated to another drone that picks up the drink and brings it to your waiting table.

该无人机看起来就像一个拥有闪亮眼睛的白色小飞碟。它会飞到顾客面前，通过相机传感器接收点餐单(你可以在4种饮品中选择一种)，然后你的选择将被传送到另一架无人机上，它会拿起饮料并送到你等候的桌前。

The drones each cost about EUR2,000 to construct, and were the result of a program celebrating the university's 60th anniversary. The 20 students behind the project, who spent nine months developing and building the autonomous² drone, aim to show how such small craft could become an essential part of modern daily life.

这种无人机的制造成本约为每架2000欧元，是庆祝埃因霍芬理工大学建校60周年的一个项目的成果。参与该项目的20名学生历时9个月研发和制造了这款自主飞行的无人机，旨在展示这类小型技术是如何成为现代日常生活中不可或缺的一部分的。

Students say their aim is to demonstrate the potential of the drones, which are useful not only up in the sky, but also indoors.

学生们表示，他们的目标是展示无人机的潜力，无人机不止是可以在天空中使用，还可以在室内使用。

"A drone can be used for fire safety, it can detect intruders, but it can also be just convenient to have a drone in your house to bring you an apple," said a student in the video presentation of the Blue Jay.

在"蓝色杰伊"的视频演示中，一名学生说道："一架无人机可用于消防安全，它可以检测到入侵者。但是在家中，一架无人机可以为你拿苹果难道不也是件很方便的事情吗？"

"We believe that one day, domestic drones will be a part of society. One day, a drone could be a friend," he added.

他补充说道："我们相信有一天，国内无人机将成为社会的一部分。有一天，无人机会成为我们的朋友的。"
