As part of a US Navy-funded project Virginia Tech College of Engineering researchers have unveiled a life-like, autonomous robotic jellyfish. The jellyfish, the size and weight of a grown man, is 5 foot 7 inches in length and wieghs 170 pounds. The project aims to develop self-powering, autonomous machines that support various missions such as surveillance and monitoring the undersea environment, as well as studying ocean life, mapping ocean floors and monitoring ocean currents.
