USV Adhemar

An unmanned surface vehicle (USV) is a small boat, which is operated remotely by a set of trained pilots without the need of a person onboard. USVs are becoming increasingly common in the world of marine robotics over the last number of years. USV Adhemar is a so-called Autonaut (Seiche), which uses the movement of the waves to produce forward motion. This means that a wave-propelled USV, like the Autonaut uses far less energy than a normal vessel at sea. This, in combination with the Autonaut’s large solar panels, allows USV Adhemar to stay at sea far longer than most USVs. Hence, the Autonaut can collect data when research vessels are not available, at a fraction of the cost. USV Adhemar is equipped for the measurement of certain environmental parameters of the water column and meteo conditions and as it is a silent vehicle, it is perfectly suited for underwater sound measurements.
