Aquanaut
Aquanaut is an unmanned underwater vehicle that can transform itself from a nimble submarine designed for long-distance cruising into a half-humanoid robot capable of carrying out complex manipulation tasks. It can inspect subsea oil and gas infrastructure, operate valves, and use tools.
FEATURES
All-electric vehicle, high level of autonomy. Operates completely untethered and does not require support ships as with traditional ROVs. The current version can travel more than 200 kilometers in submarine mode and has a maximum operational depth of 300 meters.
