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

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

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 ...

Researchers have commanded swarms of magnetic microrobots to manipulate, rotate, and assemble objects without ...
