"If you want to escape from it all and see something you've never seen, or want a great chance to see something never seen, go inside a submarine."

Mike DeGruy


Jacques-Yves Cousteau, co-inventor of Aqualung, is considered one of the most famous explorers of the sea. The French scientist made several documentaries about marine life, including Le Monde du Silence, one of the first underwater color film in history and the first documentary to be awarded with the Palme d'Or at Cannes, in 1956. Inspired by The Silent World: A Story of Undersea Discovery and Adventure, his book from 1953, is certainly a big influence for many contemporary sea researchers and oceanographers. Apart from the incomparable beauty of seascapes and marine animals, the seabed may really hold many mysteries about life on Earth.

Since that human began venturing into the depths of the oceans, significant technological and ecological discoveries have already been made because of this. Recently, in 2010, during a speech at the Mission Blue, a TED event in the Galapagos Islands for the conscious exploration and preservation of the oceans, the oceoanographer Edith Widder presented her idea of a safer way to attract marine animals for researches, and also highlighted that even today, only about 5% of the oceans have been explored by humans, and that, nevertheless, still minimal resources are actually invested in this sector if compared for example to the investments made in Space researches. Widder also noted that exploitation is the force that drives the innovation, and recalled the great importance of exploring the oceans to understand and protect the underwater systems that supports the life on earth.

Manatee™ is a concept personal submersible vehicle idealized for safe and confortable subaquatic explorations. Its control system is based on a Main Joystick, from which operator can easily command the thrusters and helms for an accurate navigation, and a Touch Screen Control Panel running its Integrated Operational System (Manatee™ IOS) with access to Safe Redundant Navigation Commands, monitors and controls for Surface Communication, Oxygen and CO2 Levels/Ambience Climatization, External/Internal Lights, SONAR Activities, Infrared and Camera Visualizations/Recordings, Engine/Battery Status, and other basic monitors and controls, as Compass, Velocity, Water Alerts, Hydrogen, Temperature, Pressure, Humidity, Depth, Pich, Roll, Heading, Altitude, Position (lat/long), Vertical Speed and more.

Reach, Autonomy and Safety

With up to 12 hours of Oxygen Supply and CO2 Removal (+100 hours reserve), up to 12 hours Battery Endurance (+100 hours reserve for communication and instruments) and it's Pressurized Cabin, Manatee™ has autonomy for deep explorations and can reach more than 9.140 meters (30.000 ft). As its interior keeps the surface pressure (1 atmosphere), theres no need for special age or physiological condition, any person can stay submerged as long as wanted, dive or surface at any rate as well.

Manatee™ IOS

Manatee™ Integrated Operational System offers a full overview and easy control of all technical parameters, and optimizes the sea exploration with dynamic functions, as Camera Auto Shots, which uses infrared sensors for animal presence detection and auto capture photos or videos with its fullHD camera. Route Creator and Route Reminder helps to create a subaquatic route planning with Depth/Altitude and GPS Data, and allows explorers to add pins marks, notes and labels with instant photos or videos over the explored hot spots, creating an interactive 3D envinroment based on SONAR seafloor maps and personal marks and notes for later virtual navigation, post processing and research.
