In the third lesson of this unit of work, your class will learn about the role of mapping in autonomous vehicles. They will then be challenged to make their robot vehicle follow a path using new hardware and software. Students will learn about how the line follower sensor on the mBot works, then use the sensor data and logic-based code to autonomously control their robots. Finally, they will relate this activity to real world driverless vehicles and discuss the other sensors needed to make driving efficient and safe.
