Sepios is a four-finned swimming robot created by students at the Swiss Federal Institute of Technology in Zürich that was inspired by the unique movements of cuttlefish. The cephalopod-esque ‘bot moves almost silently and requires no propeller, which can be harmful and stress-inducing to wildlife.
In comparison, Sepios’s propulsion system is almost silent. Its resemblance to a marine animal could also make it ideal for filming underwater wildlife.
