Vaccum Cleaner Robot
This is an Autonomous Vacuum Cleaner Robot built on a custom 3D-printed platform. It is powered by an Arduino Uno R3 and uses three ultrasonic sensors to "see" its surroundings. The drive system consists of two DC motors with wheels for movement and a third caster wheel for balance and pivoting. The robot intelligently navigates by measuring distances and steering away from obstacles, always prioritizing the path with the most open space.
Step-by-Step Guide
Hardware Assembly
Assembly & Components In this step, you will mount all electronic and mechanical parts onto the 3D-printed chassis. Components List: * 1x 3D-printed platform (Vacuum Robot V2 chassis). * 1x Arduino Uno R3 microcontroller. * 3x HC-SR04 Ultrasonic Distance Sensors. * 2x DC Motors with 2 Wheels. * 1x Caster wheel (for balance). * 1x Breadboard and Jumper wires (M/M and M/F). * 1x Battery pack (e.g., 4x AA or 9V). Tools Needed: Small Phillips screwdriver. Wire stripper or pliers. Double-sided tape or mounting screws.
Programming
Clean Code Implementation Upload the provided logic to your Arduino. The code is designed to be "clean," meaning it uses functions for specific tasks like measuring distance or turning. You can download the full .ino file from our ArduinoLab repository. Ensure the pin numbers in the code match your physical wiring. Use the Serial Monitor to calibrate the threshold distance (default is 20cm).
