Pneumatic stabilized platform

Do you remember riding on a see-saw at the playground? You sit on one end, and your friend sits on the other end. When your friend pushes down on their end, your end goes up. When your friend stops pushing, the see-saw balances out and becomes flat again.

Now, imagine a platform that can move up and down, kind of like the see-saw. But instead of your friend pushing on one end, the platform has air pressure pushing up on it from below. This air pressure is controlled by a machine, so it can make the platform move up and down very smoothly and hold it in place at a certain height.

This kind of platform is called a pneumatic stabilized platform. It's used in different situations, like cameras on helicopters or telescopes observing the stars. The platform stays still even if the helicopter or the Earth moves around, so the pictures and videos can be very clear.

In short, a pneumatic stabilized platform is a platform that uses air pressure to stay still and remain at a certain height.
