Researchers built autonomous robots the size of salt grains—with onboard computers, sensors, and motors that think and swim ...

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 ...

A tiny robot so small it can barely be seen can still "sense, think, and act" autonomously, according to the engineers who ...

Powered by light, the robots carry computers and can move in complex patterns, say Penn Engineering and University of ...

In a joint advance from the University of Pennsylvania and the University of Michigan, engineers have designed the smallest fully programmable autonomous robots ever built – ...

The robot is hard to see without a microscope. It’s small enough to rest on the ridge of a fingerprint and can operate in ...
