We have developed new, tiny robotic surgical tools that may let surgeons perform "keyhole surgery" on the brain. Despite their small size, our tools can mimic the full range of motion of a surgeon's ...

On the other hand, the easily shapeable bonded neodymium magnets made from the melt spinning process have proved particularly useful in small devices that require compact yet high-performance ...

A team at UC Berkeley has developed the world’s smallest wireless flying robot, inspired by bumblebees. Weighing just 21 milligrams and measuring under a centimeter in diameter, the miniature drone ...

Researchers in California have created an incredibly small robot that needs no battery or wired power supply to zip through ...

A tiny, soft robot that moves with magnets could crawl through debris or inside the body to find survivors, deliver medicine, ...

A new insect-inspired flying robot created by engineers at the University of California, Berkeley, can hover, change trajectory and even hit small targets. The flying robot is less than 1 centimeter ...

Permanent magnets can come in lots of different shapes ... The needle of a compass is a small magnet that can turn. It turns around until its own magnetic field lines up with the Earth’s ...
