Robot cuttlefish shows a vision for machines about how to swim

The undulating motions of the cuttlefish gave an inspiration to a group of students at the Swiss Federal Institute of Technology (ETH) in Zürich. They built a prototype nautical robot, named Sepios. It uses four special pins to make ocean life friendly propulsion so it can swim through seaweeds while not getting tangled, which is not possible  for traditional propellered boats. Also the capacity to control each of four pins individually gives the robot omnidirectionality and high maneuverability. These amazing features combined with it’s unique look and low disturbance technology will be very helpful to draw near sensitive sea creatures like dolphins and whales, and film their underwater life.
