DEvelopment Vehicle for Scientific Survey

DEVSS is an electric vehicle developed in collaboration with ISPRA. Equipped with marine or aerial propellers, it can be remotely controlled or configured for autonomous missions, with or without supervision by a human.
It can operate on surfaces up to 500 m and consists of a SAE 304 stainless steel tubular core, mounted on two neoprene inflatables that ensure its floating in water. It is designed to accommodate a watertight suitcase and additional devices, such as multi-beams, cameras, scanners, sonars, DVLs, etc.
DEVSS has been designed to obtain a semi-autonomous monitoring and environmental analysis system, but its features make it suitable for many potential uses: for example, the optical or acoustic acquisition of the seabed.
