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.
