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

Building robots that operate independently at sizes below one millimeter is incredibly difficult,” says roboticist Marc ...

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 ...

Solving a technical challenge that has stymied science for 40 years, researchers have built a robot with an onboard computer, sensors and a motor, the whole assembly less than 1 millimeter in size — ...

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

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 ...
