Not only is the tuna a strong swimmer, but the front portion of its body remains stable as it propels itself through water. This unique style of movement was the inspiration for a U.S. Navy project, which employed biomimickry practices to create the optimal design for an autonomous unmanned underwater vehicle.
The so-called tuna robot, designed in partnership with Boston Engineering, builds off the seaworthy profile of the tuna and includes a propulsion system, a single oscillating foil, appropriately placed fins, and a finely-tuned muscular and sensory control system. The full set of technology makes the tuna robot efficient at a variety of speeds, unlike a traditional thruster propulsion system, which is typically optimized to operate at a single velocity.
