University of Virginia (UVA) researchers have built a fish-inspired robot that can swim as fast as actual fish and faster than similar robots.

The 25-centimeter-long Tunabot is fabricated from three-dimensionally-printed steel and resin, and clad in elastic skin; it mimics an adolescent tuna, but lacks fins apart from the tail.

Tunabot wiggles back and forth up to 15 times a second and can attain a speed of at about one meter a second (just over 2 mph) when swimming, which is almost as fast as an actual tuna.

UVA's Hilary Bart-Smith said, “There’s still a lot to learn in terms of the roles of the different appendages on the tuna itself, like the fins that the robot doesn’t have.”
