Hydrogen Powers Robotic Jellyfish - 3/23/2012
“Robojelly” is the first successful underwater robot to use external hydrogen as a fuel source. The robot, created at Virginia Tech, mimics the movements of a jellyfish. According to Physorg, The robot is powered by heat-producing chemical reactions between the oxygen and hydrogen in water and the platinum on its surface. The heat given off by these reactions is transferred to the artificial muscles of the robot, causing them to transform into different shapes. Hydrogen fuel can also be injected at the top of the robot.
