London: 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."
