As a part of a robotic project at the Swiss Federal Institute of Technology (ETH) in Zürich, students built a nautical robot called the Sepios inspired by cuttlefish and its unique fins. Cuttlefish are “marine mollusks of the order Sepiida” and are in the same family of squid and octopuses. Sepios is the only four-finned cuttlefish robot in the world.
Sepios stands out from the rest of the classical nautical vehicles due to its “omnidirecitonality and high maneuverability.” These traits accompanied by its fishlike appearance and low disturbance make it ideal for blending in with marine life and filming marine life for research purposes.

Currently, Sepios is fully assembled and almost operational. The implementation of software with an array of additional features still awaits. Equipped with many different coordinating sensors, including a pressure and a humidity sensor, the Sepios will also have “a camera and laser for collision detection and an Inertial Measurement Unit (IMU) to measure accelerations and angular velocities.”
