The marine flatworm, the cuttlefish and the African knifefish have one thing in common: in order to propel themselves, they use their longitudinal fins to create a continuous wave which advances along their entire length. The BionicFinWave also uses this undulating fin movement to manoeuvre through a pipe system made of acrylic glass. At the same time, the autonomous underwater robot is able to communicate with the outside world wirelessly and transmit data – such as the recorded sensor values for temperature and pressure – to a tablet.
