Researchers at the University of Pennsylvania and the University of Michigan have created the smallest fully autonomous, programmable robots ever built. Barely visible to the naked eye, these light-powered microrobots can swim through liquids, sense temperature changes, make decisions, and even work together—without wires, moving parts, or external control. Using electric fields to move and tiny onboard computers to think, they can operate for months and cost about a penny each, opening the door to new applications in medicine, biology, and advanced manufacturing.
