This paper presents the design and development of a 4 in 1 Multipurpose Robot, engineered to perform a variety of tasks. The robot integrates four distinct operating modes: Voice Control, Obstacle Avoidance, Line Following, and Bluetooth Control. The Voice Control Mode allows users to operate the robot through voice commands, providing hands-free functionality. The Obstacle Avoidance Mode uses ultrasonic sensors to navigate around obstacles, ensuring smooth movement. In Line Following Mode, the robot follows a predefined path using IR sensors for precise movement along the line. The Bluetooth Control Mode enables wireless communication with the robot via a mobile application developed using the MIT app inventor, providing manual control and mode switching. Powered by an Arduino Uno, the robot uses key components including DC motors, an L298N motor driver, ultrasonic sensor, servo motor, HC-05 Bluetooth module, and REES52 IR remote and receiver module. The robot operates with minimal power consumption and the connections designed are designed to be clean and uncluttered, using fewer components to simplify the setup. The robot's design ensures flexibility and scalability for future enhancements or additional features.
