Alright kiddo, let me explain what Remus is!
Have you ever seen a submarine in a movie or a book? It's like a boat that can go under the water, right? Well, Remus is a special type of submarine called an Autonomous Underwater Vehicle, or AUV for short.
Now, the word "autonomous" means it can work all by itself, without someone driving it like a regular submarine. This is because Remus is controlled by a really smart computer inside of it.
So, what does Remus do? It explores the ocean! It has special sensors that can measure things like the temperature, salinity, and depth of the water it's swimming through. It can also take pictures of the ocean floor, find sunken ships, and even look for oil under the sea. Scientists use Remus to learn more about the ocean and the animals that live in it.
Cool, right? Now you know what Remus is and what it does!
