چکیده

Coverage is a fundamental problem in robotics, where one or more robots are required to visit each point in a target area at least once. Most previous work concentrated on finding a coverage path that minimizes the coverage time. In this paper we consider a new and more general version of the problem: adversarial coverage. Here, the robot operates in an environment that contains threats that might stop the robot. The objective is to cover the target area as quickly as possible, while minimizing the probability that the robot will be stopped before completing the coverage. This version of the problem has many real-world applications, from performing coverage missions in hazardous fields such as nuclear power plants, to surveillance of enemy forces in the battlefield and field demining. In this paper we discuss the offline version of adversarial coverage, in which the map of threats is given to the robot in advance. First, we formally define the adversarial coverage problem, and present different optimization criteria used for evaluation of coverage algorithms in adversarial environments. We show that finding an optimal solution to the adversarial coverage problem is NP-Hard. We therefore suggest two heuristic algorithms: STAC, a spanning-tree based coverage algorithm, and GAC, which follows a greedy approach. We establish theoretical bounds on the total risk involved in the coverage paths created by these algorithms and on their lengths. Lastly, we compare the effectiveness of these two algorithms in various types of environments and settings.
