This project guide is designed for intermediate Arduino enthusiasts who want to take their skills to the next level. It provides a comprehensive overview of building an Arduino-based vacuum cleaner robot from scratch. The book covers advanced topics such as sensor integration, obstacle avoidance algorithms, and remote control capabilities. You'll learn how to design and 3D print the robot chassis, select and calibrate the sensors, and program complex navigation algorithms. By the end of this project, you'll have a fully functional and customizable vacuum cleaner robot that can adapt to different environments and cleaning requirements.
