This Tiny Robot Swims Inside Your Body With No Battery!

Researchers at Leiden University have 3D printed a robot so small it makes a strand of hair look massive. Measuring just five micrometers in length, the device has no motor, no battery, and no onboard computer of any kind.
It is built from a flexible chain of microscopic segments connected by joints too small to see with the naked eye. When exposed to an electric field it begins swimming through liquid on its own, moving like a tiny snake navigating its environment.

When its path is blocked it twists and reroutes itself around the obstacle without any external instruction. What makes this particularly significant is where it could eventually go.
Robots at this scale could one day travel through the human body and deliver medication directly to tumours with a precision no conventional drug delivery method can match.
This is nanotechnology moving from theory into something that actually swims.
