Arduino-Based Vacuum Cleaner Robot

An Arduino-controlled autonomous vacuum cleaning platform is specified using ultrasonic distance sensing, differential-drive motion, and independently switched suction. An ATmega328P-based Arduino Uno processes obstacleclearance measurements and selects forward motion, braking, reverse movement, and turning while maintaining the blower state. The electrical architecture separates the traction motors from the suction load and incorporates regulated logic power. A practical verification protocol is developed for ranging, collision avoidance, duty-cycle control, collection performance, battery endurance, and floor coverage. The study integrates a system architecture, functional state transitions, engineering equations, and test-ready output visualizations. Analytical relationships and design acceptance criteria are distinguished from physical measurements, enabling reproducible prototype evaluation without attributing unmeasured values to the device.
