This project presents the design and development of an IoT-based surveillance robot aimed at reducing human casualties in war fields and other hazardous environments. The system is built around an Arduino Nano microcontroller, which acts as the central control unit. The robot is powered by a rechargeable battery supported by a solar charging circuit, ensuring reliable and continuous operation. The robot is controlled through a web browser interface using IoT technology, allowing the user to operate it remotely via an Android smart phone. An ESP32 camera module is integrated to provide real-time live video streaming. By viewing the live stream, the user can accurately control the robot’s movement and monitor the surroundings in real time. The robot is equipped with a metal sensor to detect metallic objects such as landmines or explosive devices. When metal is detected, the system immediately activates a buzzer alert and sends an email notification along with GPS location details to the concerned authorities. For mobility, an L298 motor driver is used to control the DC motors, ensuring smooth navigation. Additionally, the robot includes a headlight for visibility in low-light conditions and a laser light for indication or targeting purposes. Both can be controlled remotely through the web interface while observing the live video feed. This system is highly useful for defense surveillance, bomb detection, and security applications, minimizing human risk by enabling remote operation in dangerous environments. To achieve this task microcontroller loaded program written in embedded C language.
