Cover Story: This study tackles the task of swarm robotics, where robots explore the environment to detect targets. Our previous results confirmed that Lévy flight outperformed the usual random walk for exploration strategy in an indoor environment. This paper investigated the search performance of swarm crawler robots with Lévy flight on target detection problems in large environments through a series of real robots’ experiments. To the best of our knowledge, we are the first to investigate the search performance of swarm robots with Lévy flight in a large field. The results suggest that target exploration in a large environment would be possible by crawler robots with Lévy flight. View this paper
