The Military Spy Bomb Diffusing Robot with Live Video Surveillance is an advanced embedded systems and robotics project designed as a prototype to demonstrate the concepts used in modern surveillance and bomb diffusal robots. The robot can be remotely controlled over Wi-Fi through a web-based dashboard while simultaneously streaming live video from its onboard camera, allowing the operator to monitor and navigate hazardous environments from a safe distance.
 
The project combines an ESP32-CAM for live video streaming and web interface with an Arduino Nano dedicated to vehicle movement and robotic arm control. Communication between the two controllers is established using UART, creating a modular and industry-inspired embedded system architecture.
 
The robotic platform features a 4-wheel drive chassis, a 4-DOF robotic arm, a wire-cutting attachment, enabling remote inspection and manipulation of objects. The project also includes a Bomb Diffusion Simulation Module, allowing students to remotely identify and cut the designated wire on a simulated bomb module to stop a countdown timer and demonstrate successful bomb diffusion during project presentations.

Working Principle
 
The robot creates its own Wi-Fi network, allowing a laptop or smartphone to connect directly through a web browser. Once connected, the user can access a control dashboard that displays a live video feed from the onboard camera while also providing controls for vehicle movement and robotic arm operation.
 
The ESP32-CAM hosts the web dashboard, manages Wi-Fi communication, and streams live video. User commands received through the dashboard are transmitted to the Arduino Nano via UART. The Arduino controls the L298N motor driver for vehicle movement and the PCA9685 servo driver for precise robotic arm positioning.
 
During the bomb diffusal demonstration, the operator navigates the robot toward the Bomb Diffusion Simulation Module using the live video feed. The robotic arm is used to position the wire-cutting attachment and remotely cut one of the colored wires on the simulation module.
 
The Bomb Diffusion Simulation Module contains an Arduino Nano that continuously monitors the status of the connected wires while displaying a countdown timer on a 4-digit seven-segment display. If the designated wire is successfully cut before the timer expires, the countdown stops, the buzzer turns off, and the simulation indicates a successful bomb diffusion. If an incorrect wire is cut or the countdown reaches zero, the simulation indicates an unsuccessful operation, providing an engaging and interactive demonstration of remote robotic manipulation.
 
This modular architecture separates video processing, robotic control, and simulation logic, resulting in smooth operation and making the project ideal for educational demonstrations and exhibitions.
