Abstract
The rapid evolution of embedded systems, wireless communication, and computer vision has enabled the development of intelligent robots capable of supporting military operations. This work presents a semi-autonomous military robot powered by an ESP32 microcontroller and integrated with sensors, actuators, and remote processing capabilities. The system includes a metal detector for locating underground objects, IR sensors for autonomous obstacle avoidance, and a differential drive mechanism with an automatic digging unit triggered upon metal detection. Defense features such as a relay-based laser module and alarm buzzer are also incorporated.
Wireless communication is achieved using Zigbee modules, enabling reliable low-power control and data exchange with a laptop-based command center. A 360° surveillance camera provides real-time monitoring, supported by advanced image-processing techniques using OpenCV for face and color recognition. Based on detected threats or visual cues, appropriate commands are sent back to the robot for responses such as LED signalling, laser activation, or motion adjustments. The onboard LCD provides continuous status feedback to field users. By integrating autonomous sensing and decision-making with remote intelligence and supervision, this system demonstrates a hybrid architecture suitable for smart battlefield applications, enhancing safety, surveillance, and operational efficiency.
