Antarctica is often called the most remotecontinent on Earth. But if you ask many penguinspecies， Antarctica is anything but remote. Itis home.

This is especially true for the planets larg?est penguin， the emperor penguin. These birdsare over one metre （3.3 feet） tall and are known for making their home in the coldest placeon Earth. The males even care for eggs all through the dead of a sunless winter in the heartof the continent.

As you can imagine， this makes studying emperors very challenging for humans.Were not created to survive in this habitat. But at the same time， we desperately want toknow more about these animals. So what is the solution？ Meet ECHO—the yellow robot cre?ated to spy on penguins！

We say“spy”， but in truth， ECHO is more of a roommate to one particular colony ofemperor penguins. It doesnt attempt to hide itself. Instead， it walks （or rather， wheels） itselfright up to the birds that it is observing. As for the birds， they will sometimes curiouslycheck out the robot. But for the most part， they ignore it and go about their business. This?works out well for the scientists who created ECHO， the Woods Hole Oceanographic Institu?tion （WHOI） in Massachusetts， USA. As long as scientists can first capture and tag （給……加上標(biāo)簽） a penguin with a taped?on microchip， ECHO can do the rest.

It moves among the birds， scanning their tags， and giving scientists information abouthow the birds move around—when they leave a certain area， when they return， or if theychoose not to return at all. And it can do these all without exposing the birds to a constanthuman presence—or exposing human researchers to exhausting work in the brutal cold.

Scientists are observing the emperors habits to better understand the threats to us andthe rest of the planet. Thanks to the data collected by ECHO， we would now know how to in?vestigate！
