2011年的日本地震后,宾夕法尼亚大学的一个团队和仙台东北大学合作吧四旋翼用于灾区,在前大学教授实验室主任伟杰库马的带领下获得惊人的成果。

(CNN) -- It's a mesmerizing, surreal scene. Eighttiny, unmanned aerial vehicles -- called quadrotors -- begin to rise from theground in unison.

这是一个让人入迷的梦幻场景。八个被称为四旋翼的小型无人飞行器从地面同时起飞。

Theyhover at eye level, filling the room with a heavy buzzing sound. Then they movethrough a makeshift window, one at a time, and reform as a group on the otherside.

它们在眼前盘旋,整个房间都充满了嗡嗡响的声音。它们一个接一个通过一个临时窗口,然后在另一边再重新编队。

Thisisn't happening on a Spielberg set, and it isn't science fiction. Thesereal-life flying robots are at the University of Pennsylvania's General Robotics, Automation, Sensing andPerception Lab.

这不是斯皮伯格的电影也不是科幻小说。它们都在宾夕法尼亚州大学的机器人自动化感应技术实验室。

"Thisis a robot that's completely autonomous," said doctoral student MatthewTurpin, "and by that I mean there's no remote control in thebackground."

博士生马修特平说“这些机器人是全自动的,没有任何遥控操作”

The labis a mechanical engineer's dream. Quadrotors in all shapes, sizes and colors --and in various degrees of assembly -- cover nearly every surface. Shelves linethe walls, filled to the brim with tools and toys.

这个实验室是机械工程师的梦想。各种形状,尺寸,颜色,还有各种不同组件的四旋翼到处都是。墙上的架子堆满了工具和玩具。

Mostnoticeable is the lab's state-of-the-art Vicon motion-capture system. Infraredcameras placed throughout a test-flying area communicate with tiny sensors onthe
quadrotors, feeding into a computer-based navigation system.

最引人注意的是实验室的尖端动态捕捉系统(Vicon)。安装在试飞区的红外摄影机与四旋翼的探测器互相联系再传送给电脑的导航系统。

"Wehave the Vicon system, or the red lights, which allow us to figure out wherethe robot is," Turpin explained. "Then we're able to send it commandsabout what we'd like it to do and group behaviors that you'll see."

“我们使用的Vicon系统可以让我们计算出机器人的位置。”特平解释说“我们就可以发出指令指挥单个或者整体的行动。”

 
Turpingives the quadrotors simple instructions via computer, but the vehicles decidehow to get from Point A to Point B on their own. The results are a dazzlingdisplay of formations, from spinning in circles in midair to navigatingobstacles in sync with each other.

特平通过电脑向四旋翼发出简单的指令,但是机器会自行决定如何从A点到B点。从空中旋转到互相配合导航通过障碍物,令人眼花缭乱。

Otherquadrotors at the GRASP Lab have worked together to carry cargo and buildstructures.

其他的四旋翼则互相合作搬运和修建建筑。

"Theserobots are able to pick up these simple, almost LEGO-like bricks, and they'reable to carry them from one location to another," Turpin said.

特平说:这些机器人可以捡起像LEGO的小砖块然后搬运到另一处。“

Butperhaps the quadrotors' most memorable moment was when they played instrumentsto perform the James Bondtheme song. The video has more than 3 million views on YouTube.

最让人影像深刻的是它们用乐器演奏占士邦的主题曲。那个视频在youtube上有超过300万个点击。

As muchfun as Turpin and his colleagues seem to be having, he says their ultimate goalis to put quadrotors to good use outside the lab.

特平和他的同事一样开心,他说他们目标是把四旋翼用在户外。

After the2011 earthquake in Japan, a team from the University of Pennsylvania and TohokuUniversity in Sendai took quadrotors into the disaster zone. Led by VijayKumar, a former GRASP Lab director and professor at Penn, they achieved someremarkable accomplishments.

2011年的日本地震后,宾夕法尼亚大学的一个团队和仙台东北大学合作吧四旋翼用于灾区,在前大学教授实验室主任伟杰库马的带领下获得惊人的成果。

Amongthem: sending quadrotors -- equipped with cameras and lasers -- into anunstable building to see what sort of information they could gather.

他们吧装有摄影机和激光的四旋翼送进不稳定的建筑里收集信息。

"Wewent into a collapsed building; we mapped three floors," Kumar said."We got three-dimensional maps, and we were able to show that this sort ofthing is feasible today."

库马说“我们绘制了一栋倒塌大楼的其中三层的三维地图,我们展示了这种方法是可行的的。”

Quadrotorscould also use sensors to detect radiation levels and other biological hazards,Kumar said. That could help keep first responders out of harm's way.

库马还说四旋翼还可以使用探测器侦测辐射和生化污染。这就可以保护第一批反应人员的安全。

"Clearly,humans will always have a role to play in emergency response for lawenforcement," Kumar said. "But if there's an emergency, if there's a911 call, the question is, do you want a human dashing off to respond to itright away?"

库马:“无疑,人在应急执法中的作用是无可替代的,但问题是如果有紧急情况,你需要人第一时间参与反应吗?”

Kumaralso saw an opportunity for quadrotors to be used when law enforcement wasclose to apprehending a suspect in the Boston bombings.

库马还看到了四旋翼在警察逮捕波士顿爆炸案嫌疑人时可发挥的作用。

"Afterthe tragic incident in Boston, you saw that robot actually ripping away thecanvas on top of the boat to try to look behind the cover" for thesuspect, he said, "It's an excruciatingly, painfully slow operation. Whatwe'd like to do is accomplish these tasks really quickly."

他说“悲剧发生后,你可以看到警用机器人撕开小艇的帆布以寻找嫌疑人”,“行动缓慢得让人痛苦。我们希望可以很快的完成这些工作。.”

There areplenty of positive uses for quadrotors. But the concept of stealthy,camera-toting robots does cause concern for some people.

四旋翼有很多正面的作用。但是隐身和携带摄影机的机器人让一些人感到不安。

Kumaroften fields questions about misuse of the technology and privacy concerns.
"Ithink we should engage in a public dialogue about when to use them, what thepotential benefits are, and recognize that we can protect ourselves againstabuse of these devices -- as opposed to saying 'we don't want to develop this,'" he said.
For now,most of the research on these robots is still done in the lab. But you couldsay their potential is sky high.

库马常常回应一些科技的不当使用和隐私的问题。
他说“我认为应该和公众讨论它的使用时机和潜在好处,这样我们就会认识到如何防止滥用这些设备,而不只是说“我们反对开发这种技术”
目前,这种机器人仍然处于试验阶段。但是有很高的的潜力
