The first fish swimming fast, swimming like fish

A graduate student at the Massachusetts Institute of Technology (MIT), the United States has successfully developed a soft robot that can operate under water at a phenomenal pace in the wild.

The fish robot is the first robot capable of performing fast-paced physiological movements such as fish in nature, developed by MIT graduate student Andrew Marchese. With a 0.1 second interval, the robot is able to change direction, avoiding obstacles encountered, which can be compared to the speed of escape of fish in the natural environment.

Because of the waterproof silicone rubber, the outer body of the robot is quite soft, without causing any scratches to the objects around when impacted. Its conversion is based on the principle of moving the carbon dioxide inside .

The soft-robotic robot is composed of the following main parts, the head having an electronic microchip control module and a box of carbon dioxide located in the abdomen of the robot. These two parts are connected by two hose pumps, which are placed along both sides towards the tail of the robot. The opening of the nozzle controls its movement speed, the number of times the pump will control the direction of change of the robot.

"Robots can operate independently and achieve high performance," said Marchese . With fast speeds and high body curves, soft robots can perform some tasks that hard robots can not do. "

The research has contributed to the problem of the constituent materials and the mechanism of action for the development of counterfeit products in the future. In addition, it can help graduate students collect data on wildlife in nature.
