Festo Developed Cuttlefish-Inspired Robot BionicFinWave


German Automation Company showcased new BionicFinWave inspired by the cuttlefish robot at the Achema 2018 tech trade show in Frankfurt

In 2014, Scientists at Northwestern University have also created a cuttlefish-inspired robot called as Sepios. In March 2018, Festo, German electrical automation manufactured unveiled two robots inspired by animals, which includes crawling/rolling spider and a flying fox bat. Recently it launched BionicFinWave, which moves like a cuttlefish. BionicFinWave showcased at the Achema 2018 tech trade show, Frankfurt autonomously swam through a network of clear acrylic pipes with the help of pressure sensor, which allowed it to gauge its depth within the water. Furthermore, it features ultrasound sensors, which measures distance between the wall and device. The robot is capable of transmitting its pressure readings, along with data such as water temperature to a tablet located outside of the pipes.

The cuttlefish moves forwards and backwards through the water via two continuously-undulating fins that run along both sides of its body. The robotic fish BionicFinWave is 3D-printed, which is equipped with two fins made from highly-flexible silicone. Each fin is moved by nine integrated lever arms, which are connected via a flat crankshaft to one of two servo motors housed within the robot. Those motors operate independently of one another – this lets the two fins undulate at different speeds and in opposite directions, allowing the robot to turn left or right on the spot. It moves up and down via a third motor that it uses to bend its articulated body accordingly.

However, the company did not disclose any information regarding real-world applications of BionicFinWave. It can be used for performing underwater tasks such as inspections or data collection, monitoring of water, sewage, and other process industries. It’s conceivable that the unusual propulsion system could also lend itself to crafts such as future submarines.
