University Submersibles - Underwater Robots
This news highlights some of the major universities projects in submersible technology exhibited at
EXPO21XX. Universities engaged in this advanced submersible research include Rutgers –COOL, Hawaii, North Eastern, MIT, Essex, just to mention a few. These technologies will enable among other things, the survey of the sea bed habitat, underwater research tasks, the discover of deep-water ecosystems and objects recovery.
The Rutgers University’s
Coastal Ocean Observation Lab, COOL focuses on the bio-physical processes of the ocean. In April, 2009, COOL launched a small underwater robotic glider off the coast of New Jersey in an attempt to be the first underwater robot to cross the Atlantic Ocean. The glider was christened The Scarlet Knight (see image). The autonomous underwater vehicle, or glider, converts changes in vehicle buoyancy to vertical motion with a pair of fixed wings providing forward momentum to move horizontally through the ocean. Most of the gliders are reserved for glider mechanics, battery storage and communication equipment, as well as scientific payload. Other miniaturized physical and bio-optical instruments measure in situ water properties such as temperature, salinity, and the absorption and scattering of light in the water column, have been and are currently under development for placement in the glider’s science payload bay. Data from experiments show that Scarlet travels vertically approximately 2200 kilometers (almost 1400 miles), and moves more forward then up and down when it is flying.

The University of Hawaii at Manoa started its
SAUVIM (Semi Autonomous Underwater Vehicle for Intervention Mission) in 1997 to find solutions to problems posed by Autonomous Underwater Vehicles (AUVs). AUVs commonly have low bandwidth and significant time delay in communicating or remotely operating a manipulation system, making it impossible for remote controllers to react to problems in a timely manner. SAUVIM addresses this challenging task. With no physical link and with no human occupants, SAUVIM permits intervention in dangerous areas and deep ocean, or for in missions to retrieve hazardous objects and in classified areas.

One of the projects at the
Marine Science Center of the
Northeastern University is the 8-legged Lobster-robot
underwater robot equipped with remote sensors for autonomous remote-sensing operations in rivers and/or the littoral zone ocean bottom with robust adaptations to irregular bottom contours, current and surge.

The
Hatsopolous Microfluids laboratory (HML) of
MIT has developed a battery-powered robotic snail and a clam-inspired RoboClam as a smart-anchor. The RoboSnail uses modes of locomotion that snails employ to travel across their trails of slime or lubrication layers to propel it to a target.

Essex Robotics of the
University of Essex has developed an aquatic man-made robotic systems, called Robotic Fish, which uses undulation movements to provide energy and thrust in place of the conventional rotary propeller
(see image).

The robotic fish has similar features to fishes such as swimming behavior and autonomously navigating ability. These features enable the autonomous robotic fish to react and navigate through its environment and to its charging station.
