The micro-robot is the size of a single biological cell, and scientists hope it will open the door to a vast array of medical applications.


This article by Paul McClure, writing for New Atlas, makes the following points:
  • The robot navigates using both electricity and magnetic fields.
  • The micro-robot is propelled using a magnetic field.
  • It requires no fuel or direct contact with body tissues.
  • Inspired by ‘swimmers’ such as bacteria and sperm, the micro-robot can move around the body autonomously.
