This project presents a multi-robot system designed for battlefield surveillance and hazard detection, leveraging a swarm architecture. The system comprises a primary unit, equipped with a Raspberry Pi, which integrates metal, sound, and ultrasonic sensors for detecting mines, harmful sounds, and obstacles. Additionally, the primary unit utilizes a GPS module for real-time location tracking and a Pi camera for live surveillance and person recognition. Two assisting robots, communicating with the primary unit via ZigBee modules, are equipped with similar sensor capabilities to enhance situational awareness. Upon detection of an unknown individual or hazardous sound, the assisting robots autonomously follow the primary unit, facilitating collaborative exploration and threat assessment. A web application interface provides secure user access for live streaming, enabling users to monitor the battlefield in real time along with the associated timestamps and location data. The proposed system aims to improve operational efficiency and safety in hazardous environments by utilizing coordinated robotic actions for effective surveillance and threat detection.
