Building a robot that can operate well and last long underwater presents a myriad of challenges, vastly different from those encountered on land or in the air.

You can think of underwater robots as our "avatars" sent to the deep sea. The ocean is incredibly deep, with immense pressure, and it's dark and cold.

Okay, talking about underwater robots, it's actually not that complicated. You can think of them as two main categories, plus a few "branches.

Hello, regarding "fake news," it's indeed a headache-inducing problem. I'll try to share my thoughts in plain language, hoping it can help you.

Here's the English translation: Hey, when it comes to news ethics, it's not as mysterious as it sounds. You can think of a good journalist as a reliable "messenger" or a "referee" in a ball game.

This is actually an excellent question, and it's one that many people are confused about. My view is this: Absolute, complete objectivity is almost impossible to achieve in reality.

Hello, I'll try to explain my understanding in plain language, hoping it helps you. What is News? You can think of news as "something that just happened, is somewhat related to you, me, and everyone e...
