The proposed IoT War Field Surveillance Robot with Voice and Web Control is designed for remote surveillance and monitoring in hazardous and inaccessible areas. The system uses an Arduino UNO as the main controller, an ESP32-CAM for live video monitoring, an HC-05 Bluetooth module for voice-based control, a stepper motor for left and right camera movement, and DC motors for robot movement and GUN movement. The robot can be controlled through voice commands using a Bluetooth-enabled mobile phone. Voice commands are used to control the robot movement, camera left/right rotation, and the gun-shaped demonstration module. The robot can move forward, backward, left, right, and stop, while the stepper motor rotates the ESP32-CAM left and right according to the voice commands. The demonstration gun-shaped module can also be controlled through voice commands for safe ON/OFF demonstration purposes. In addition, the system provides IoT-based control through a web interface. The user can access the system using a smartphone to control the robot movement, rotate the camera left and right, and operate the demonstration payload. The ESP32-CAM provides live video streaming through the web interface, allowing the user to monitor the surrounding area remotely while controlling the robot and GUN. An L298 motor driver is used to control the robot's DC motors, l293d motor drivers are used to control the GUN, while the stepper motor provides directional movement of the camera. The system therefore combines Bluetooth voice control and IoT web control in a single surveillance robot. The system can be useful for security surveillance, military training, hazardous-area inspection, disaster monitoring, industrial inspection, and remote reconnaissance applications, reducing the need for humans to directly enter potentially dangerous environments.          

Features of the project include:  

1. Voice-Controlled Robot Movement – Controls forward, backward, left, right, and stop functions through Bluetooth voice commands.
2. Voice-Controlled Camera Movement – Controls the stepper motor to rotate the ESP32-CAM left and right for wider surveillance.
3. IoT Web-Based Control – Allows remote control of the robot, camera, and demonstration GUN module through a smartphone web browser.
4. Live Video Monitoring – ESP32-CAM provides real-time video streaming through the web interface for remote surveillance.
5. Demonstration GUN Control – Provides safe ON/OFF and movement control of the non-functional gun-shaped demonstration module using voice commands and the IoT web interface.
