Meet Tunabot: a robotic fish that is able to perfectly mimic a yellowfin tuna that researchers say can help improve water propulsion
- Tunabot is designed to look and mimic a yellowfin tuna
- The robot is 10 centimeters long and can swim 15 centimeters per second
- Researchers hope that robots can pave the way for stronger drive systems
It is the first of its kind – a robotic fish that mimics the speed and movements of a yellowfin tuna.
This water machine is called the & # 39; Tunabot & # 39; and can reach a maximum tail stroke frequency of 15 Hertz, allowing him to swim 15 inches per second.
Researchers hope that this creation will lead to the development of more powerful and efficient drive systems.

& # 39; Tunabot & # 39; is a water-inspired robot that is almost 10 centimeters long and can reach a maximum tail stroke frequency of 15 hertz – allowing it to swim 15 centimeters per second. it mimics the speed and movements of a live yellowfin tuna
The robotic fish was developed by a team of mechanical engineers from the University of Virginia School of Engineering, with a collaboration of biologists from Harvard University.
& # 39; Our goal was not just to build a robot. We really wanted to understand the science of biological swimming, & # 39; said Hilary Bart-Smith, a professor of mechanical and aerospace engineering.
& # 39; Our goal was to build something that allowed us to test hypotheses about what makes biological swimmers so fast and efficient. & # 39;
The aim of this project is to understand the physics of fish propulsion with the aim of developing technology that mimics their movements to design strong propulsion systems for underwater vehicles.
To design the fish, Bart-Smith and her team began to learn and understand how powerful swimmers navigate the water – especially the swimming dynamics of yellowfin tuna and mackerel.
Using that data, Bart-Smith and her team, research scientist Jianzhong & # 39; Joe & # 39; Zhu and Ph.D. student Carl White, built a robot that not only moved like a fish under water, but hit its tail fast enough to reach almost comparable speeds.

Tunabot is eyeless, finless and is about 10 centimeters long – a live yellowfin tuna can reach up to seven feet. The team designed the robotic fish with a green laser in the middle that measures the movement of its tail
Tunabot is eyeless, finless and is about 10 centimeters long compared to a live yellowfin tuna that can grow up to seven feet.
The robotic fish uses a green laser, found in the middle of its back, to measure the movement of its tail.
& # 39; So far we see in the fish robot literature that there are really great systems that others have created, but the data is often inconsistent in measurement selection and presentation. It is just the current status of the robotics field at the moment.
& # 39; Our Tunabot article is important because our extensive performance data sets the bar very high, & # 39; said White.
The relationship between biology and robotics is circular, said George V. Lauder, professor of biology at Harvard.
& # 39; One reason I think we have a successful research program in this area is because of the great interaction between biologists and robotics. & # 39;
Researchers started by learning and understanding how powerful swimmers navigate through the water. And that is when George V. Lauder, professor of biology at Harvard (photo) and his team of researchers precisely measure the swimming dynamics of yellowfin tuna
& # 39; We do not assume that biology has evolved to the best solution, & # 39; said Bart-Smith.
& # 39; These fish have long had time to evolve towards a solution that will allow them to survive – especially to eat, reproduce and not be eaten. & # 39;
Niet Not limited by these requirements, we can only focus on mechanisms and functions that promote higher performance, higher speed, higher efficiency. & # 39;
