HOLLOW MAGNETIC NANOCARRIER-BASED MICROROBOT SWARMS FOR DEFENCE APPLICATIONS

Recent advances in swarm robotics and nanomaterials have enabled the development of intelligent microrobotic systems with potential applications extending beyond biomedical domains. This work presents a novel approach employing hollow magnetic nanocarrier-based microrobot swarms designed for defense-oriented operations such as surveillance, targeted neutralization, and environmental sensing in hazardous zones.The proposed system integrates magnetically responsive hollow nanocarriers with high surface area to volume ratios, enabling multifunctional payload encapsulation and remote field-driven actuation.A collective control strategy based on magnetic field modulation and swarm intelligence algorithms is employed to coordinate large-scale microrobot behaviors, including dynamic reconfiguration, obstacle avoidance, and cooperative task execution. Simulation and experimental analyses demonstrate the swarm s ability to self-organize, navigate complex terrains, and perform distributed sensing with high robustness and fault tolerance. The hollow architecture further allows adaptive payload delivery, such as the release of neutralizing agents or signal beacons, enhancing tactical versatility. The results highlight the feasibility of employing magnetic nanocarrier-based microrobot swarms as a next-generation platform for autonomous micro-scale defense systems, offering scalability, resilience, and precision in dynamic operational environments.
