World’s Smallest Autonomous Programmable Robots Created by Penn & Michigan Engineers

Summary:

Researchers at the University of Pennsylvania and the University of Michigan have developed the world’s smallest fully programmable, autonomous robots — tiny microrobots measuring about 200 by 300 by 50 micrometers. These tiny machines operate independently, sensing and responding to their surroundings without tethers or external control and can run for months on microscopic power sources. The breakthrough, published in Science Robotics and the Proceedings of the National Academy of Sciences, opens entirely new horizons for robotics, particularly in medicine and advanced manufacturing. Potential applications include monitoring individual cell health, targeted drug delivery, and construction of microscale devices. Powered by light and equipped with onboard computing, sensing, and locomotion capabilities, this achievement pushes the boundary of autonomous robotics down to biological scales.
