Abstract: This paper presents the development of a cost-effective Arduino-based wall- following robot capable of navigating enclosed environments autonomously. The design incorporates ultrasonic sensors for distance measurement, servo motors for movement control, and the Arduino Uno as the central processing unit. We detail the design principles, electronic circuitry, programming logic, and sensor calibration necessary for wall-following algorithms. The robot demonstrates stable navigation along walls and avoids obstacles dynamically. The system is ideal for applications in surveillance, automated inspection, and educational robotics. The simplicity, modularity, and affordability make it an excellent prototype for real-world deployment and academic experimentation.
