... areas, rivers, natural and artificial lakes. The ASV acts as a bridge for communication with a remote station, that in this way can receive data from the ROV, avoiding the necessity of a supply vessel to operate the ROV (Scaradozzi, Conte and Sorbi, 2012; Conte et al., 2016). Examples of cooperation...
