Robot jellyfish fuelled by hydrogen
Robojelly Fig. A is the computer design for Robojelly. Fig. B is the silicone bell Robojelly, powered by hydrogen fuel, out of the water. The pins on the bell are used for deformation. Tadesse et al/IOP Publishing A new robotic jellyfish is powered by hydrogen, and could theoretically never run out of energy as it pulses through the sea. It's designed to work as a search and rescue or surveillance 'bot for the U.S. Navy. Researchers at Virginia Tech have been studying the mechanisms of jellyfish propulsion, which take place in a couple of ways. Muscles inside the jellyfish bell contract, and the bell folds in on itself like a closing umbrella. This contraction pushes water out from under the bell, propelling the jellyfish forward. The bell regains its ovoid shape when the muscles relax, and the cycle repeats. Creating a soft robot that can mimic this motion requires special materials - rigid skeletal structures can't replicate the graceful flexing of an invertebrate. To do this, lead researcher Yonas Tadesse
