EurekAlert  September 18, 2019 Working under a U.S. Army project a team of researchers in the US (Georgia Institute of Technology, Northwestern University) built robots entirely from smaller robots known as smarticles, unlocking the principles of a potentially new locomotion technique. The 3D-printed smarticles can do just one thing: flap their two arms. But when five of these smarticles are confined in a circle, they begin to nudge one another, forming a robophysical system known as a “supersmarticle” that can move by itself. The devices can change their location only when they interact with other devices while enclosed by a […]
