BionicFinWave: underwater robot "from the distant past"

Most of our usual roboticsuses pneumatic devices or electric motors for movement. But it would be much more effective to develop a structure like a musculature. And if such technologies for ground-based robots are far from complete, then a similar system for underwater robots can be implemented now. This is what engineers at the Festo robotic company did. Their robot, called BionicFinWave, uses the same principle of movement as underwater animals, and, according to developers, the movements of the robot are more similar to how the marine inhabitants moved “hundreds of thousands of years ago.”

The BionicFinWave robot has solid fins,Made of soft silicone plastic. And to move using 2 servo. At the same time, the “body” of a robot, like sea animals, is able to bend, and the robot itself can move not only forward or backward, but generally in any direction: change the depth of immersion, turn and so on. It is also noteworthy that the BionicFinWave is a fully autonomous robot. He does not need cables or power cables. The battery charge lasts for several hours of work, and control is carried out remotely from the shore, ship or submarine.

However, despite a lot of interesting finds,BionicFinWave is rather a prototype, not a complete device. The fact is that the company Festo rarely “keeps with it” its own achievements. Other companies can take design elements and, on their basis, create their own robots that can be used both for monitoring the underwater flora and fauna, and for reconnaissance and rescue missions.
