How Does a Self-Driving Car See? (Waymo's system explained)?

A self-driving car uses special eyes and smart brainpower to see what’s around it, just like you do when you ride in a car with your mom or dad.

Imagine the car has many cameras, like having 12 friends all looking out of the windows at once. These cameras take pictures of everything, other cars, people walking, traffic lights, and even the road itself. It's like taking a photo every second while you're driving through town!

How it thinks

Once the car has these pictures, its brain (called the computer) looks at them closely to understand what’s going on. It knows if a person is crossing the street or if a red light means "stop." This brain uses maps and information from sensors, like how your phone helps you find your way when you're lost.

The car also has radar and lidar, which are like super-detailed rulers that help it measure distances. It's like having a special ruler that tells the car exactly how far away the next car is, even in the dark or when it’s raining!

With all this help, the self-driving car can drive safely, just like you!
