Miniature Origami Robot Self-folds, Walks, Swims, and Degrades
Oh, the possibilities! This tiny little thing they call a miniature origami robot is a unique drone specimen which weighs a third of a gram and is just 1.7 cm long. It starts out as a flat paper or polystyrene wafer which once activated via a small heat source, folds itself up into the complex shape you see above and can begin to do various tasks such as swim, climb a slope, carry a load and more!
The drone's movement, recently revealed by MIT, is "powered" by two sets of magnets: a neodymium magnet integrated into the robot itself and another four electromagnetic coils located under the operating surface that attract and repel the onboard magnet as needed.
