What are digital twins?

A digital twin is like having a robot copy of something real that you can use to try out ideas before doing them for real.

Imagine your favorite toy car, it zooms around on the floor, and sometimes it crashes into walls or other toys. Now imagine if there was a robot version of that toy car inside a computer. You could make that robot car go fast or slow, turn left or right, and see what happens without crashing anything real. That robot copy is like a digital twin, it helps you learn how to play better with your toy car.

Think about a digital twin as being like a mirror for something real. If the thing in the real world moves, the mirror version moves too. But the mirror can also do things the real one can’t, like pretending it’s flying or turning invisible so you can see what happens.

Sometimes people use digital twins to help fix big machines or even whole buildings before they break down, kind of like giving them a practice run inside a computer!
