🚘 Self-Driving Car

A Self-Driving Car is used for using sensors and computers to drive without a human steering.

🔌 How Does a Self-Driving Car Work?

A self-driving car is covered in sensors. Cameras read lane lines and traffic lights, radar measures how far away other cars are, and some cars have a spinning laser sensor called lidar that builds a 3D map of everything nearby. A computer combines all this information many times a second and decides how to steer, speed up and brake.

🌟 Where You'll Find a Self-Driving Car

Self-driving taxis already carry passengers in a few cities, and many ordinary new cars use parts of the same technology to help drivers, such as staying in their lane or braking on their own. Self-driving trucks and delivery robots are being tested on some roads, too.

🏫 Classroom Activity

Have children draw a self-driving car with sensors that help it "see," then talk about what those sensors watch for on the road.

🏠 Homeschool Activity

Play a pretend game where your child is the car's computer, deciding when to "stop," "go," or "turn" based on pictures you show them.
