ELI5: Explain Like I'm 5

Automated Transfer Vehicle

An automated transfer vehicle (ATV) is like a mini-train that can move things around on its own. It's like a little robot that can carry things from one place to another. It's like a driverless car but it carries items instead of people. It has a program that tells it where to go and it follows the path exactly, no matter how far. This makes it easier and faster to move things around, and it saves people from having to do the work themselves.
