Five Identical (IMAGE) U.S. Army Research Laboratory Caption Five identical "smarticles" -- smart active particles -- interact with one another in an enclosure. By nudging each other, the group -- dubbed a "supersmarticle" -- can move in random ways. The research could lead to robotic systems capable of changing their shapes, modalities and functions.
