S creates a soft machine that is not only waterproof but also perfectly imitates the fast and elegant movement of the fish.
Andrew Marchese, a graduate student at the Massachusetts Institute of Technology (MIT)
Create a soft external robot to learn more about the behavior of fish.
The robot fish is the first, says MIT.
Contains autonomous soft robots capable of rapid body movement and will be published in their new soft robot magazine.
Robot fish was designed by Andrew Marchese from MIT.
Its 3D housing is made of silicone rubber and changes direction in one second.
Its movement is controlled by the carbon dioxide released from a jar in the abdomen. The fish is made of silicone rubber, changing direction in a second, and carbon dioxide is released from the jar in the robot\'s abdomen.
As soon as the gas is released, it passes through a channel with a long fluctuation, causing the tail to bend in the opposite direction.
The fish performs up to 30 switching actions before the carbon dioxide tank runs out.
Daniel La Ruth, director of the lab for computer science and artificial intelligence at MIT, said: \"We are excited about soft robots for many reasons.
When robots penetrate into the physical world and begin to interact with people more and more, if the robot\'s body is very soft, it is much easier to make them safe, and there is no danger if they hit you.
\"The fact that the body is constantly deformed gives these machines an infinite range of configurations, which cannot be achieved by hinge-type machines.
Marchese built the fish in a Russian lab, where other researchers are working on Printable robots.
He made a mold with a 3D printer in the lab, in which he cast the fish tail and fish head with silicone rubber, as well as a polymer ring that protects the electrons of the fish internal organs.
Each half of the fish tail, and subsequent movement, varies depending on the diameter of the nozzle that releases gas to the Channel and the time it remains open.
During the test, Marchese found the angle of the fish changing direction-
Can be as extreme as 100 degrees.
It is almost entirely determined by the duration of the inflation, and its speed is almost entirely determined by the diameter of the nozzle. This so-
The two parameters, Marchese says, are called \"decoupling\", which biologists observe in real fish.
Marchese says the robot he designed looks like a fish, but didn\'t expect it to mimic the motion of the creature so well, especially the decoupling nature of swimming.
\"The fish was designed to explore performance for a short time --
Continued Marchese.
The next step in future research is to adopt the system and build some systems that are compromised in performance.
But it will increase life.
Future versions of fish are expected to swim for about 30 minutes in a row and will be inflated using pumped water instead of carbon dioxide.
Ross also envisioned that robots could be used to infiltrate real fish and gather information about their behavior in natural habitats.
