This work presents a fast and secure distributed coverage control algorithm to enable a multi-agent system to cooperatively inspect and reconstruct infrastructure. 1) a group of agents is tasked with exploring partially known areas to survey the surface of the target infrastructure and perceiving obstacles continuously. They need to cooperatively seek load-balanced deployment in real-time to improve the efficiency of coverage. 2) gradually perceived obstacles might stop the agent from exploring the environments or cause unpredictable damage to the agents.

In this work, a decentralized control policy to encircle and capture an evader is introduced, which allows pursuers to efficiently trap the evader, increasing greater chance of a successful capture in large, open, obstacle-rich areas with random initial configurations.

Multi-agent systems have increasingly become instrumental in tackling search and coverage problems. However, the challenge of optimizing task efficiency without compromising task success still persists, particularly in expansive, unstructured environments with dense obstacles. This work presents an innovative, decentralized geometric separation based controller for search and coverage to reactively navigate these complexities while maintaining safety without deadlock.
