Robots inspired by animals are fairly common: most of the time, whenever there's a certain spot on Earth we want to send a robot, there's already an animal that can navigate there with ease. So it makes sense to borrow those animal traits for the bots.

And since under the oceans are a frontier we still haven't fully explored, there's a handful of robotic fish already in existence. But a new autonomous robotic fish made by German engineering company Festo still stands out for the extremely sleek and wavy way that it moves, mimicking the undulating movements of a cuttlefish.

Meet BionicFinWave, who you can see gliding in action below:



By adding silicone fins that move in a wave-like motions, the robot's body can easily connect to them with nine tiny lever arms and they don't require any heavy struts or supports. The fins can also move independently of each other, allowing BionicFinWave to more easily thrust itself forward or backwards while underwater, or smoothly turn whenever it needs to.

And it requires very little power, needing only two small servo motors to control the fin levers and a third servo motor in its head to help it swim upward or downward. When let loose in an underwater environment, it can move completely on its own and communicate with its human operators, who likely feel much like Aquaman while they're talking to this fish.

This is far from Festo's first robotic animal, as the company has crafted autonomous robotic bats, spiders, dragonflies, and even kangaroos. By adding this robo-cuttlefish to its arsenal, they can expand their mechanical domain to the waters now.
