At nearly 14 inches long, the new tuna-inspired robot was created by researchers at the University of Virginia. It can flutter its tail as fast as real tuna. (seven times per second) and swims at 1.5 miles per hour. or two body lengths per second.In a new article in Science Robotics,
the team behind this creation describes how they built a tuna-like robot. This is a machine that can contract or loosen the tail joint to move at different speeds. This mechanism allows tunabots to reach high speeds while still saving energy. It's a method that could one day help improve swimming robots and even underwater vehicles.
Trading stocks is not profitable. Turn to play ทางเข้าเกม slots online. It must be said that trading stocks is not an easy task that anyone can do, they can trade and earn profits. Because people who really trade with the hope of profit, have to study the information for years, which what we want to say is If you are not ready for everything, or people who trade no matter how much they make, they never make a profit.
Several robot researchers have piloted their own Robofish. "We're different because we study the physics [of real fish] rather than just mimicking shapes or diagrams to create something like a real robotic fish," said Qiang Zhong, a postdoctoral researcher at UVA and first author of the paper. The team analyzed the video of the real tuna to come up with the flow physics of its motion
