Tunabot Robot Swims Fasts as a Tuna

Tunabot Robot Swims Fasts as a Tuna
The swimming Tunabot robot can mimic the swimming of the yellowfin tuna, offering researchers a useful model for studying fish biodynamics.

The Tunabot was created by a team from the University of Virginia in cooperation with the U.S. Navy. Made up of a 3D-printed steel frame covered in a plastic skin, the finless, 25 centimeter-long robot mimics the tuna’s tail motion to move through the water faster than any robotic fish to date. In addition to learning more about the mechanics of fish movement, the design could also be incorporated into new forms of underwater propulsion.
