Tiny robots drifting in the air is the ultimate goal of an experiment in jellyfish design at NYU. From Sandrine Ceurstemont at New Scientist: “Tiny flying robots usually mimic nature’s flyers, like birds and insects – but perhaps that’s due to a lack of imagination. A four-winged design created by Leif Ristroph and colleagues at New York University, which boasts a body plan reminiscent of a jellyfish, is more stable in the air than insect-like machines.”
