Tiny Smart Robots That Run for Months Without Wires

Researchers from the Universities of Pennsylvania and Michigan have created the smallest fully autonomous robots ever built, measuring less than a grain of salt. These robots can move in liquid environments, detect temperature changes, make decisions, and operate for months without wires or external control. They move by influencing the liquid around them and use sensors to adjust their behavior and cooperate. This technology is considered a platform for future developments in robotics.
