CREATING A MILITARY ROBOT EQUIPPED WITH A FIREARM TO OPERATE REMOTELY FOR KEEPING PERSONE OUT OF HIGH RISK ENVIRONMENT

The development of the Military Robot with Firing mechanism using RF control and an ESP32-CAM module successfully demonstrates the integration of wireless communication, mobility, and surveillance in a single compact robotic platform. After extensive design, coding, and testing, the prototype achieved its primary goal of enabling a human operator to remotely control the robot’s movement, view its surroundings through live video streaming, and fire a projectile or simulated weapon on command. The RF transmitter and receiver pair functioned effectively within the expected range of up to 30 meters in open areas. Commands such as forward, backward, left, right, and fire were successfully transmitted to the receiver module connected to the ATmega328P microcontroller. The microcontroller processed these commands and controlled the L293D motor driver to operate the four DC motors accordingly, allowing precise maneuvering of the robot. The servo motor also performed reliably, allowing the gun mechanism to be aimed left or right before firing. The firing mechanism, connected through a relay and controlled via a digital pin on the microcontroller, was tested using a small actuator to simulate shooting. The activation of the firing system responded with negligible delay from the operator’s command, confirming the stability of the system. The integration of the ESP32-CAM module added significant value to the project. The camera module was programmed to either connect to a local Wi-Fi network or create its own access point, allowing the user to view live footage on a mobile or PC browser using a static IP address. The video feed quality was sufficient for basic surveillance and targeting in daylight conditions. This real-time visual feedback allows the operator to navigate the robot in complex environments and observe the surroundings without direct line of sight. Overall, the robot fulfilled all its intended functions with consistency and reliability. The combination of mobility, firing capability, and live video feed demonstrates a foundational model for unmanned military systems. It also provides insight into how low-cost microcontrollers, wireless modules, and sensors can be combined to build practical solutions for defense and surveillance applications.
