The main objective of the project is to advance the state of the art of underwater robotics applied to interventions in archaeological sites. Thus, on the one hand, the semi-autonomous manipulation capacity in scenarios with occlusion of objects is being investigated, and on the other hand the improvement of the wireless communications system and the compression of images, in a way that allows (if necessary) the mobility of the submarine vehicle without umbilical. In addition, supervised control by the remote operator will be allowed, taking into account the restrictions of the network.
