Okay, so imagine you have a toy car that you like to play with. The car has four wheels and a body that sits on top of the wheels.
Now, if you try to move the car forward, the wheels will also move forward, right? That's because the wheels are attached to the body of the car and they move together.
But what if you wanted to make the car turn left or right? You would need to make the wheels turn in different directions.
That's where a rocker box comes in! A rocker box is like a special part of the toy car that helps you make the wheels turn in different directions.
Instead of being attached directly to the body of the car, the wheels are attached to a little piece of metal called a rocker. The rockers are then attached to a bigger piece of metal called the rocker box.
The rocker box is attached to the body of the car in a way that lets it tilt back and forth. When you tilt the rocker box to one side, it makes the rockers move in different directions, which makes the wheels turn in different directions too. And that's how you can make your toy car turn left or right!
So, think of a rocker box like a special part of a car that helps you control where it goes. It's kind of like the way your parents use the steering wheel to make the car turn when you're driving with them.
