不会吓跑真鱼的机器鱼

REC

Most robotic fish are like fish out of water: They’re surprisingly poor swimmers, and they often scare away any other creatures they come in contact with.

大部分的机器鱼都不不像是真正的水里的鱼：它们游得很烂，而且经常会吓跑它们遇到的其他生物。

But a new robot is so realistic that fish in Fiji are falling for it—hook, line, and sinker.

不过有一种新的机器鱼实在是逼真，以至于斐济的鱼儿们都喜欢它—它就像鱼钩，线和沉饵一样。

The remote-controlled robofish isn’t the world’s first.

这只遥控机器鱼并不是全世界第一只。

But the new version—called SoFi, for Soft Robotic Fish—is a step up from previous generations of robotic fish because it can be maneuvered up and down to depths of up to 18 meters.

不过这个新版—叫做SoFi，意思是柔性机器鱼—是以前几代机器鱼的升级版因为可以控制它上下游动，到达18米深的水里。

There’s a fisheye camera where its mouth would be, perfectly positioned to capture any action up ahead.

它的嘴的部分安装了一个鱼眼摄像头，其位置是为了完美地捕捉前方的动向。

And the robot doesn’t just look like a fish; it also moves like one, undulating its tail to propel itself through the water.

而且这个机器人不仅仅看起来像鱼；它游起来也很像，通过波动它的尾部来推进自己在水里前进。

Scientists took SoFi for six test runs in coral reefs around the Pacific island of Fiji.

科学家们带着SoFi在太平洋的斐济群岛周围的珊瑚礁进行了六次测试。

The robot, which is 47 centimeters long, swam at speeds of half a body length per second.

这台机器鱼，长47厘米，游泳的速度是每秒钟半个其身长。

That’s a tad slower than most real-life fish, which can swim two to 10 body lengths per second.

这个速度比大部分真实的鱼都要慢，真实的鱼游速可以达到每秒10个身长。

And it could swim for 40 minutes at a time, controlled by a diver up to 10 meters away, the team reported today in Science Robotics.

这条机器鱼一次可以游40分钟，由10米外的一个潜水员来控制，其开发团队今天在《科学》杂志的机器人分刊发表了报道。

The Fijian fish didn’t seem to mind SoFi swimming around.

斐济的鱼儿们似乎并不介意SoFi在它们周围游来游去。

So the team hopes that the robot and its camera can be deployed elsewhere to help us peer into the lives of marine animals—to better see how they move, what they’re eating, and who they’re swimming around with.

因此研发团队希望他们的机器鱼和摄像头可以用在别的地方来帮助我们观察海里动物的生活—来更好地看清它们如何运动，它们吃什么，以及它们跟谁一起游动。
