The 4 in 1 Arduino Robot is a multifunctional robotic system designed to perform various autonomous navigation tasks such as line following, object following, obstacle avoiding, and line following with obstacle avoidance. The robot is developed using an Arduino Uno microcontroller as the main control unit, which processes input signals from ultrasonic and IR sensors to control the robot’s movement intelligently. The system uses two IR sensors for line detection, two additional IR sensors for object following, and an ultrasonic sensor for obstacle detection and distance measurement. An L298 motor driver module is used to control the DC motors for robot movement, while a servo motor helps in directional sensing and obstacle scanning. LED indicators provide visual status information for different operating modes. The robot can switch between multiple functionalities using control buttons, making it highly flexible and efficient for automation and robotic learning applications. The proposed system demonstrates the integration of embedded systems, sensor technology, and motor control for smart robotic applications in education, research, and industrial automation.
