A robot is an automated programmable machine capable of performing tasks with precision, speed, and minimal human intervention. Robots are widely used in industries, healthcare, defense, and domestic applications to improve efficiency and reduce manual effort. However, robots have drawbacks such as high implementation cost, limited decision-making ability without advanced AI, and potential job displacement in certain sectors. Therefore, this project proposes a Design and Implementation of an Arduino UNO-Based Bluetooth Controlled Robotic System. The system is built around the Arduino UNO microcontroller, which acts as the central processing unit to control and coordinate all operations. A Bluetooth module enables wireless communication between the robot and a user device such as a smartphone or computer, allowing real-time control of movement functions including forward, reverse, left, right, and motor ON/OFF operations. The motor driving mechanism is achieved using an L298N motor driver module, which controls the speed and direction of BO motors connected to the wheels. A relay module is incorporated to manage higher voltage switching operations, ensuring safe and efficient power control. The system operates using dual power supplies, with a 5V battery powering the microcontroller and communication module, and a 12V battery supplying power to the motors and relay circuit. The proposed robotic system offers advantages such as low cost, simple hardware design, ease of implementation, and reliable wireless control, making it suitable for surveillance, remote operations, educational purposes, and industrial automation applications.
