A group of mechanical engineering students at ETH Zurich in Switzerland have created an omnidirectional underwater robot, dubbed Sepios, that is inspired by the cuttlefish.
The cuttlefish is a fascinating creature that using a pair of undulating fins to move forward and backward, turn on the spot or hover in position. Therefore it's a good source of inspiration when you're putting together an underwater robot that is flexible in movement yet immune to getting tangled up in its own propellers. In addition, Sepios has been given an extra set of fins that allow it to move straight up and down.
The robot can function for 90 minutes on a full battery charge and can access depths up to 10 meters. It is expected to be particularly useful for observing and filming marine life.
