Opening Autonomous Driving
Intelligent Era
German Karl Benz invented the world’s first horse-drawn three-wheeled vehicle in 1885 and obtained the world’s first automobile invention patent on January 29, 1886, which has been 134 years ago. This day is known by most people as the birthday of the modern automobile, and Benz is honored as the “Father of the Automobile”.
Today, cars have become an indispensable means of transportation, and they are also the most favorite model type for children. Humanity has been dedicated to researching how to make cars smarter, thus making travel more comfortable, faster, and safer. Today, we will also make a four-wheel drive smart car together, let’s explore how to make cars smarter.

What should we do?
1. Draw the design of the smart car (Understand length units centimeters, millimeters, recognize angles: right angle, acute angle, obtuse angle; master the method of measuring length, learn to use a ruler and triangle ruler for smart car design) 2 times
2. Use a screwdriver and pliers to assemble the smart car (Understand the concepts of motors, motor drivers, controllers, expansion boards, electronic breadboards, power supply, and positive and negative poles) 1 time
3. Rush Forward (Understand Arduino programming software, understand the concepts of voltage, current, digital signals, and analog signals, use digital output to control the smart car to move forward and stop) 1 time
4. Autonomous Driving (Understand the principles of controlling turning actions, use programming software to control the smart car to perform actions such as moving forward, turning, reversing, and braking) 1 time
5. Robot’s Eye – Ultrasonic Sensor (Understand the concepts and uses of ultrasonic waves, sound waves, and infrasound, use ultrasonic sensors to complete obstacle detection tasks) 1 time
6. Remote Control Programming (Add remote control functionality to the smart car, and master how to achieve remote control functionality through programming) 1 time
7. Competition Task (Complete the jungle adventure competition task and present the design of the work)
