Case 09 Follow the car at a fixed distance
This course aims to guide students to learn the application of graphical programming and sensor technology by using Cutebot Pro intelligent racing car to make a case. Students will learn how to program a car to follow the car in front while maintaining a certain distance. In the process of achieving this goal, students will involve knowledge points such as judgment, branching, and logic operations of program design, and understand the working principle of ultrasonic sensors.
Understand the principle and application of ultrasonic sensors.
Learn to use graphical programming tools to write programs to realize the function of following the car.

Hello everyone! Today we will use the Cutebot Pro smart racing car to make an interesting case. Have you guys seen this smart race car? It has ultrasonic sensors that help our car perceive its surroundings. Our goal is to allow the car to follow the car in front and keep a certain distance. This will require us to use graphical programming and sensor technology to achieve this.
