Gazebo

Gazebo is like a giant dollhouse for robots! Just like how you might play with small toy robots in a dollhouse, grown-up scientists and engineers use gazebo to play with real-life robots without actually being near them.

It's a special computer program that lets people make a model of a robot and test out how it moves and behaves in different situations, without having to build a real robot or risk hurting someone if something goes wrong.

Think of it like this: when you play with your toy robots in your dollhouse, you can control what they do and how they move around. With gazebo, scientists and engineers can do the same thing with real robots, but on a much bigger and more complex scale. It's like they're playing with a real-life robot dollhouse!
