The project aims in designing a War Field Spy Robot which is operated wirelessly through a smart phone using IoT technology. This is an Internet of Things (IoT) based project that uses an ESP32-CAM module, laser light, headlight, PIR sensor, buzzer, two DC motors, and an L298 motor driver for surveillance and security applications. The robot is equipped with an ESP32-CAM mounted on it, through which live video streaming can be viewed remotely. The interesting feature of this project is that the robot can be controlled in forward, backward, left, and right directions from a web browser over the internet. The ESP32-CAM captures live video data from the surroundings and sends it to a particular IP address through Wi-Fi. The user can access the robot using a mobile phone and control the robotic vehicle while viewing the live video feed. The system also includes a headlight for night vision assistance and a laser gun for target indication. In addition, a PIR sensor is used to detect human movement or enemy presence in the war field. Whenever motion is detected, the buzzer automatically turns ON to provide an alert indication for security purposes. A 12V rechargeable battery is used to provide power supply to the robot, LM2596 module provide 5VDC to the ESP32-CAM, sensors, and other modules. The main controlling device of the project is the ESP32-CAM module, which is interfaced with all input and output devices for efficient operation.
