Energy Efficient, Hydrogen-Fueled Robot Can Swim Like a Jellyfish

Energy Efficient, Hydrogen-Fueled Robot Can Swim Like a Jellyfish

Between airborne drones, spycams that can see around walls and a flood of other new surveillance devices, it’s beginning to seem like the only place you can go for real privacy is deep-sea diving. Well, guess again. Researchers at Virginia Tech are working with the U.S. Navy to design Robojelly, a seagoing reconnaissance robot that looks like a jellyfish , “feeds” itself like a jellyfish and propels itself under water by pulsing, just like a jellyfish. As if there aren’t enough jellyfish in the sea already! Harvesting energy from the environment Robojelly is still in the initial stages of development so it still has a ways to go, but the finished concept is for a device that can supply its own energy through a reaction between oxygen and hydrogen in seawater, using platinum as a catalyst. The reaction creates enough energy in the form of heat to operate the robot’s propuls...
