Nature continues to supply models for robots. RobotNext found this article on robot jellyfish. Many robot builders are modeling every type of motion nature provides. Jellyfish use a unique swimming motion to achieve their flowing, pulsing motion.
So now to the basic story. Two Korean researchers have developed a robot that swims like a jellyfish. Engineers Sung-Weon Yeom and Il-Kwon Oh from Chonnam National University in the Republic of Korea explain in an article at PhysOrg.com that "Jellyfish are one of the most awesome marine animals, doing a spectacular and psychedelic dance in water." A special type of polymer that imitates muscle movement was used in the design of this jellyfish robot. The article goes on to state that “advances in electro-active polymers (EAP) enabled them to achieve this biomimetic swimming behavior in a robot.”
