Inspired by marine planarian, cuttlefish, and Nile perch, BionicFinWave has been designed further for tasks like inspections or data collections underwater. It’s an underwater robot based on bionic technology platform, this robot comes with unique fin drive just like those marine planarian that use their fins in order to propel themselves, these fins generate a continuous wave that advances along their entire length, helping them to move. BionicFinWave underwater robot also maneuvers through a pipe system made of acrylic glass, it has the ability to communicate with outside world wirelessly and transmit data, it helps to speed up data collection process underwater.
Designed by Festo, BionicFinWave underwater robot is designed with attention to details, the fins just like on the natural role models start from head to tail and are located either on the back, stomach, or both sides of the body. This concept robot also adopts the similar mechanism with its bionic fins located on its sides, the wave-shaped movement of these fins would allow it to push water behind and create a forward thrust. Made from silicone, the fins are flexible enough to implement fluid wave movements, they are each fastened to nine small level arms. The arms are driven by two servo motors located in the body of this fish robot. Each fin can move individually to generate different wave patterns, this ability helps to create slow and precise movement when needed.
