Abstract
In order to improve the efficiency of a terrain covering algorithm for underwater robots (AUVs), an artificial island (AI) technique is applied. This technique reduces the path length and the operating time of the AUV as compared with conventional covering algorithms, when the AUV explores an unknown three dimensional underwater environment. In this paper, the concept of the artificial island technique is used and it is expanded in multi-AUV system. Its validity is proved under certain conditions. Through simulations, the validity of this technique with multi-AUV is confirmed in terms of the total path length and the time cost of the AUVs.
