Measuring just 200 by 300 by 50 micrometers — smaller than a grain of salt and roughly the size of a single-celled paramecium ...

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 ...

Scientists have built microscopic, light-powered robots that can think, swim, and operate independently at the scale of ...

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

Despite their size, the robots can navigate liquids, respond to their environment and operate without external control.

Scientists have created robots smaller than a grain of salt that can sense their surroundings, make decisions, and move ...

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

There is no avoiding robots. With increasing autonomy, satellites span the skies; vacuums vroom underfoot; and bots conduct surgery, deliver packages and explore the solar system. Robot expert Sooyeon ...
