Instead of physical contact, these 300-micrometer robots use fluidic torque — creating controlled whirlpools in the surrounding liquid to exert force on objects ...

Magnets can move metal objects without even making contact—but how do they do that? In this video, you’ll learn how magnetic fields are formed, how poles attract and repel, and where we see this ...

Tiny magnetic microrobots spinning in liquid can generate fluidic torque strong enough to move gears and objects without any physical contact.

Researchers have developed a technique to move objects around with a jet of wind. The new approach makes it possible to manipulate objects at a distance and could be integrated into robots to give ...
