Hydro
The HydRO projects aims at making available autonomous water surface and under-water vehicles equipped with sensors for maritime studies and geophysics. Echo sounding is a technique for measuring water depths by transmitting acoustic pulses from the ocean/sea/lake surface and listening for their reflection (or echo) from the seafloor.
Video recording and processing under specific illumination spectrum, is helping the reserachers to identify underwater species, fixed infrastructure and other objects. The multitude of on-board sensors brings a complete image of the environment.
