A micromouse is like a robot mouse that can go through a maze all by itself without a person helping it. The maze is like a big puzzle where the mouse has to find the way out.
The micromouse has special sensors that help it see where it is going and figure out where the walls are so it doesn't run into them. It also has a computer brain that helps it make decisions on which way to turn and where to go.
The goal of the micromouse is to find the exit of the maze as quickly as possible. It's like when you play hide and seek, but you have to find the way out of a tricky maze instead of finding your friends.
People make micromouses as a fun way to learn about engineering, programming, and problem-solving. It's like building a puzzle and then seeing if your creation can solve it on its own.
