Robotic Jellyfish Fuelled By Hydrogen Invented -- BBC
Engineers in the US say they have invented a hydrogen-powered robot that moves through water like a jellyfish.
Development of the robot, nicknamed Robojelly, is in the early stages but researchers hope it could eventually be used in underwater rescue operations.
Writing in Smart Materials and Structures, Yonas Tadesse said the jellyfish's simple swimming action made it an ideal model for a vehicle.
Being fuelled by hydrogen means, in theory, it will not run out of energy.
Mr Tadesse, the lead author of the study, said: "To our knowledge, this is the first successful powering of an underwater robot using external hydrogen as a fuel source."
