Abstract

In this paper, we propose a optimal deployment method for cooperative exploration of swarm robots. The proposed method consists of two parts such as optimal deployment and path planning. The optimal area deployment is proposed by the K-mean Algorithm and Voronoi tessellation. The path planning is proposed by the potential field method and A* Algorithm. Finally, the numerical experiments demonstrate the effectiveness and feasibility of the proposed method.

본 논문에서는 군집로봇의 효과적인 협조탐색을 위한 탐색영역에 대한 군집로봇의 최적배치을 제안한다. 먼저, 탐색영역에 대한 최적의 배치를 위해 보로노이 테셀레이션과 K-mean 알고리즘을 이용하여 탐색영역을 분할한다. 분할된 영역을 안전한 주행을 위해 전역경로계획과 지역경로계획을 한다. 전역경로계획은 A*알고리즘을 이용하여 전역경로계획을 하여 최적의 전역경로를 찾고, 지역경로계획은 포텐셜 필드방법을 이용하여 장애물 회피 통해 안전하게 목표점에 이르게 한다. 마지막으로 제안한 알고리즘은 시물레이션을 통해 그 응용가능성을 검토한다.
