Abstract: This paper presents the design and implementation of a Gesture Controlled Metal Detector Car Using Arduino, which is an intuitive and natural solution for controlling a robot car's movement using hand gestures. The system combines multiple components, including an ultrasonic detector, Bluetooth module, flex sensor, accelerometer, metal detector, and Arduino board, to recognize hand movements and control the robot car wirelessly. Additionally, the system integrates a metal detection process using a metal detector device to identify landmines in high-tension areas, enhancing security for defense systems. The metal detector is mounted on the robot car and continuously scans the ground while the car moves, providing real-time alerts when metallic objects are detected. This crucial functionality aids in landmine detection, making the system practical for defense and security applications. The motion control system uses a flex sensor to track finger movement and an accelerometer to measure hand motion. The Arduino board processes the data from these sensors and sends appropriate commands to control the robot car's motors via Bluetooth. Experimental results confirm that the system effectively responds to hand gestures and accurately detects metallic objects, demonstrating its viability in real-world applications. This study contributes to the field of human-robot interaction by offering a hands-free, user-friendly, and wireless system for controlling robotic systems. The system's advantages include ease of use, hands-free control, wireless communication, and enhanced security through metal detection. However, it also presents limitations such as a limited range of motion and gesture recognition capabilities. Despite these challenges, this design opens the door for further exploration and improvement in gesture-based control technologies, particularly in areas such as education, accessibility for individuals with disabilities, entertainment, and defense applications.
