The AutoSub6000 is an autonomous robotic submarine that is being used by the UK's National Oceanography Centre to explore life forms on the deep sea floor. This submarine, which is equipped with a high-resolution photography system, is more effective at identifying deep-sea life than usual scientific trawling methods.
This impressive machine is capable of autonomously traveling through pre-programmed deep-sea routes without a tether. It continuously maps the sea floor as it traverses the deep sea. It is capable of accessing depths of up to 6,000 meters and staying there for up to 70 hours per a full charge of its lithium-polymer battery pack.
The robotic submarine captures photos of the sea floor using its downward-facing camera. The images are then analyzed by scientists to identify the creatures that are captured in them.
