Researchers creating flexible fin to make AUVs more agile

If a wave of déjà vu just hit you like a ton of bricks, fret not, as this most certainly isn't the first (or second) time we've heard of researchers looking to the seas to create more intelligent / nimble submersibles. Apparently, a few more folks have gotten involved, as gurus from Drexel, MIT, Harvard and George Washington are now collaborating to develop a "fish-like fin to make autonomous underwater vehicles (AUVs) more agile." Apparently, the current iteration has improved on prior versions by eliminating drag during part of the "cut and sweep" motion. The general idea is to combine several of the fins in order to "allow robotic submarines to hover and turn on a dime as natural swimmers can," but it'll still be quite some time before devices such as this one can overcome ocean currents and ill-willed sea creatures.
