Thanks to millions and millions of years of evolution, sea turtles work. They work well. They can swim stealthily around the ocean, sliding between chunks of coral if necessary. That in mind, it’s no wonder the sea creatures are the inspiration for the latest underwater robots.

Even if they aren’t mutated into teenage ninjas, turtles might one day be a viable alternative to drones for espionage and surveillance. They come already armor-plated, they’re amphibious, they’re powered by plants, and thanks to their natural desire to avoid obstacles, researchers have found a clever way to even make them remote controllable.

Mankind’s attempts to create robotic humans that move exactly like us have so far been far from perfect. They usually stumble around, desperately trying to keep their balance like a toddler taking its first steps. But recreating the natural motions of underwater creatures like sea turtles? We’ve damn near perfected that. More »
Sure you could have a robot assist you around the home, or even one that’ll make factories friendlier, but we’ll opt for a robot sea turtle any day of the week. The Swiss folks over at ETH Zurich are working on making that a reality with the Naro-Tartaruga, a turtle-inspired machine that would swim efficiently while carrying cargo in its shell. It’s currently a cylindrical aluminum vessel with a couple of flippers, but concept designs include that totally bad-ass bot in the image above. The turtle-bot has a top speed of over 7 knots, so it’ll handily beat any real sea turtle in a race, and the big torso has enough space for battery and sensors that are necessary for autonomous function. The fins on the turtle have a fully three-dimensional mechanism — there are three actuators per fin, and each actuate the fin axle independently. The end goal is for the development of underwater autonomous vehicles, which will hopefully bring us one step closer to SeaQuest DSV. In the meantime, we’d like one just so we can freak the hell out of our cats.
