China unveils ‘ghost jellyfish drone’ disappears into the deep sea, leaving people wondering what it’s watching underwater

China has unveiled a transparent, jellyfish-shaped bionic robot for stealth underwater exploration. Developed by Northwestern Polytechnical University, this “ghost drone” mimics real jellyfish movements using soft hydrogel and low-energy actuators. Equipped with AI and a camera, it silently observes marine life and identifies underwater objects, marking a significant leap in eco-friendly deep-sea monitoring.
