London, March 21 (IANS) A hydrogen-powered robot that moves in water like a jellyfish and could eventually be used in underwater rescue operations has been invented by US engineers, the BBC reported Wednesday.

The robot, nicknamed Robojelly, is in the early stages of development.

Writing in Smart Materials and Structures, Yonas Tadesse, of Virginia Tech in the US, 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.

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.”
