American scientists have developed micro robots
Scientists at the Argonne National Laboratory (Argonne National Laboratory) have created self-organizing micro robots with a diameter of about 500 microns (0.5 mm).
Formed from tiny ferromagnetic particles floating in an interlayer between water and oil, these robots (microbots? Nanorobots?) Are controlled by magnets. Using an alternating magnetic field directed perpendicular to the surface of the liquid, the particles are collected in circles, called "asters", and with the help of a horizontal field they are set in motion.

The most important thing in this discovery is the accuracy that magnetic control provides. The video shows how these robots are used to transport tiny objects, or to transport a group of even smaller particles. In the first roller, a three-millimeter bead acts as a load; in the second, particles with a diameter of up to 0.15 mm.
In the short term, these micro-robots can be used for targeted delivery of doses of chemistry (or other drugs) to cancer tumors, so as not to expose the entire body to harmful effects. In the future, they can be used for the manufacture of some smallest details. The ultimate goal of robots is to complete the task and then dissolve in the liquid practically without a trace. It is not difficult to imagine a huge tank with robots producing silicon chips or, say, plastic cups.
It is important to realize that self-organization does not mean self-awareness and the ability to work independently or communicate in a group. However, control over the production line, equipped with these robots, can theoretically take over the computer. And start the production of their own kind ...
