Jellyfish inspires latest ocean-powered robot
Date:3/20/2012

regenerate fuel from its natural surroundings and therefore doesn't require an external power source or the constant replacement of batteries.

At the moment, the hydrogen-powered Robojelly has been functioning whilst being clamped down in a water tank. The researchers admit that the robot still needs development to achieve full functionality and efficiency; however, the potential can be seen in this video (http://www.youtube.com/watch?v=U2OSJQhHQp8) where the robot is powered by electricity.

"The current design allows the jellyfish to flex its eight bell segments, each operated by a fuel-powered SMA module. This should be sufficient for the jellyfish to lift itself up if all the bell segments are actuated.

"We are now researching new ways to deliver the fuel into each segment so that each one can be controlled individually. This should allow the robot to be controlled and moved in different directions," Tadesse continued.

This study is part of the MURI program sponsored by Office of Naval Research.
