It’s not as suave as 007, but it’s more discreet: scientists backed by the US military have developed a new kind of spy which can patrol the oceans disguised as a jellyfish. The robot, known as robo-jelly, Consists of two silicone bell-like structures that fold and unfold like an umbrella, reports the New Scientist. Connecting the umbrella are “muscles” that contract to make the robo jelly move.
It requires no batteries, as it is powered by the hydrogen and oxygen in seawater. These react with the robot’s platinum- powder coating to produce heat, and the only waste released is more water. “It can stay underwater and refuel itself while it is performing surveillance,” said lead author Yonas Tadesse, of the University of Texas at Dallas.
