Underwater Fin Could Break Speed Record

Underwater Fin Could Break Speed Record | Biomimicry | Scoop.it

"Animal Dynamics, a company formed of biomechanics from the University of Oxford’s Department of Zoology, islooking to break the human-powered water speed record in a canoe propelled by an underwater fin, mimicking the way that dolphins or whales swim. The team believes that a flapping fin design could be a more efficient than a traditional propeller mechanism, as it works with the natural flow of water, rather than against it. Instead of using paddles, the catamaran-style canoe has a hydrofoil under its bow which is operated by a driver using a pedaling system. The cycling motion drives a fin downwards through the water, creating the thrust to propel the canoe forwards."

Synthetic Shark Skin Swimsuits Make Swimming Faster

Synthetic Shark Skin Swimsuits Make Swimming Faster | Biomimicry | Scoop.it

"Harvard scientists say that they've managed to replicate one of the most fascinating organs of the animal kingdom in a lab. Their finely-detailed synthetic shark skin could make some of the fastest underwater robots around, and maybe even one day grace human wetsuits or the hulls of ships."

Speedo's New Nemesis Fins are Making Waves

Speedo's New Nemesis Fins are Making Waves | Biomimicry | Scoop.it

"Speedo’s cutting edge new Nemesis Fins are making waves in the swimming world. The most comfortable fitness and swim training fin on the market, Speedo’s new Nemesis Fin was designed using biomimicry and inspired by the pectoral fin of the Humpback Whale. The scalloped outer edge of the fins, like that of the Humpback Whale, creates greater surface area for water to pass over versus a smooth, straight edge. This technology creates enhanced propulsion, allowing the swimmer to push more water during kicking drills and training sets."

Robot Octopus Shows Off New Sculls

Robot Octopus Shows Off New Sculls | Biomimicry | Scoop.it
"Octopi are pro swimmers, thanks (at least in part) to that octet of arms they've got going on. They've adopted a particular swimming gait called sculling, which works great for them, but until they start publishing scientific papers, we're missing out on all of their gait testing data. Roboticists have had to start from scratch, and along the way, they've experimented with some swimming gaits that we've never seen a real octopus try and pull off."
