NEW VIDEO: Magnetic Micro-Robots!
Added 2019-04-25 15:55:38 +0000 UTCSo I had no idea this research was a thing until last week. There have been a number of papers published recently about the things you can do by manufacturing devices with particular magnetic properties.
You can drive them with external magnetic fields to grasp, roll, and jump. These could be used for internal medicine application.
Smaller robots have been shown to form swarms that can take many different forms to help them navigate the human body. There are even tiny magnetic 'tweezers' being used to poke organelles inside living cells. Apparently how an organelle responds to pressure can be used to diagnose diseases.
