The eel robot, whose length is 30 centimeters, is designed to work in salt water.
In most cases, marine biologists are engaged in studying underwater flora and fauna, using apparatus equipped with sufficiently noisy propellers or water jet engines. Despite attempts to camouflage such devices, their appearance introduces dissonance into the underwater world, frightens and turns into the flight of marine animals. However, thanks to the efforts of researchers from the University of California in San Diego and Berkeley, scientists have an absolutely quiet, transparent and soft robot, the appearance of which remains almost invisible to most marine inhabitants.
The robot is set in motion not by a traditional engine, but by artificial muscles made from a special elastomer. The electricity necessary for its operation is supplied through thin conductors enclosed in a transparent shell. A positive electric charge is supplied inside the water pocket in the artificial muscle, and a negative potential is supplied to the surrounding water. Due to the difference in potentials, a weak electrical current begins to flow, which causes the artificial muscles to flex, moving the robot forward or backward at a speed of 1.9 millimeters per second.
The new robot has already been tested in the laboratory of the Scripps Oceanographic Institute in a tank, in which, in addition to the robot, there were corals and live fish. In the near future, scientists plan to slightly change the geometry of the body of the robot and the configuration of artificial muscles, which will increase the efficiency of its movement. In addition, the next version of the robot will already have a camera and several sensors.
"Creating a robot, we used the marine environment as one of the elements of its design," says Professor Michael T. Tolley, "And in the near future we are going to create a new robot that will have its own source of energy and can act independently, without being tied to anything. "
