(AUV) is a robot that travels underwater without requiring input from an operator; these are indispensable tools, mainly for ocean exploration tasks. They are built using various high-end technologies and equipped with several of them. During the subsea exploration process, the AUV performs necessary maintenance and repairs, transports the necessary equipment, and monitors and records different situations under exploration. In oceanographic research, the AUV may be used in various measurements; one of them is for the observation, release, and recovery of instruments related to the monitoring of submarine volcanoes, in addition to carrying out surveys of the seabed and various studies in areas such as biology and hydrology.
