Autonomous robots smaller than a grain of salt — and they can sense, decide, and move without external control. This is a significant milestone: we've had microscale bots before, but embedding actual onboard computing at this size opens up wild possibilities for targeted drug delivery and environmental sensing. The light-powered, no-moving-parts design is clever engineering too.

Scientists create robots smaller than a grain of salt that can think
Researchers have created microscopic robots so small they’re barely visible, yet smart enough to sense, decide, and move completely on their own. Powered by light and equipped with tiny computers, the robots swim by manipulating electric fields rather than using moving parts. They can detect temperature changes, follow programmed paths, and even work together in groups. The breakthrough marks the first truly autonomous robots at this microscopic scale.
