Researchers build a robotic swarm with no electronics, no batteries and no brains

A LEGO brick is not smart. It doesn’t compute. It doesn’t plug in. It just fits. A team of Georgia Tech researchers has applied that logic to robotics. Bolei Deng, an assistant professor in Georgia Tech’s Daniel Guggenheim School of Aerospace Engineering, and Xinyi Yang, an aerospace engineering Ph.D. student, build swarms of tiny robotic particles that latch, release, and reorganize without a single electronic component. No sensors, no processors, and no code.
