'RoboClam' replicates a clam's ability to burrow while using little energy
The Atlantic razor clam uses very little energy to burrow into undersea soil at high speed. Now a detailed insight into how the animal digs has led to the development of a robotic clam that can perform the same trick.
Robotic fish aids understanding of how animals move
The weakly electric black ghost knifefish of the Amazon basin has inspired Northwestern University's Malcolm MacIver and an interdisciplinary team of researchers to develop agile fish robots that could lead to a vast improvement ...
R/V Sikuliaq to winter in Great Lakes, test 'hybrid' underwater vehicle
The National Science Foundation's (NSF) research vessel (R/V) Sikuliaq will spend its first winter on the Great Lakes before making the long journey to its home port in Seward, Alaska. Sikuliaq, pronounced ...
Whale of a difference: Researchers double depth at which technology can identify whale prey
Shipboard echosounders can help scientists find and identify life in the ocean, from schools of fish to diving seabirds and even flurries of tiny krill.
NOAA, government and academia partners deploy underwater robots to improve hurricane science
A fleet of underwater robots is descending into waters off the east coast to collect data that could help improve storm intensity forecasts during future hurricane seasons. Several regions of the NOAA-led U.S. Integrated ...
Robotics team diving into deep end at RoboSub competition
A student team based in the University of Alberta's Faculty of Engineering has taken its underwater robotic vehicle to an international competition in the United States this week.
Fish-tracking robots take to the seas and skies off Portugal
A unique field experiment being conducted off the coast of Portugal this week combines ocean robotics and marine biology in a complex aquatic dance. Researchers are using a fleet of robotic vehicles to track ...
New underwater robot swims and senses like a fish
In recent years, robotic underwater vehicles have become more common in a variety of industrial and civil sectors. They are used extensively by the scientific community to study the ocean. For example, underwater ...
Robotic fish navigate flowscapes
The EU funded European research project FILOSE has developed robots with a new sense - lateral line sensing. All fish have this sensing organ but so far it had no technological counterpart on man-made underwater ...
Tiny reef speedster challenges tuna in the ocean sprint
(Phys.org)—Tiny coral reef wrasses can swim as fast as some of the swiftest fish in the ocean – but using only half as much energy to do so, Australian scientists working on the Great Barrier Reef have found.
Underwater robots smart enough to explore treacherous deep-ocean terrain
(Phys.org)—Engineers at Stanford's Department of Aeronautics and Astronautics and the Monterey Bay Aquarium Research Institute have developed autonomous underwater vehicles that can photograph regions of ...
First 3-D map of under the East Antarctic sea ice
For the first time in East Antarctica, climate scientists have produced a three-dimensional (3-D) map of the surface beneath a sea ice floe, revealing an inverted complex topography evocative of lakes and ...
Aquatic robot audits health of seabed
The watery depths of Western Australia's Ningaloo coast will be audited by marine engineers and scientists this week using an aquatic robot and technology developed by University of Sydney mechatronic experts.
Scientists call for protection of deep sea coral reefs from European fishing fleets
A team of scientists is calling for the urgent introduction of marine protected areas after producing evidence of long-term damage being done to deep-sea coral reefs by European fishing fleets.
