Microrobots move thanks to magnets

Magnetically controlled microrobots using the so-called smart grid or smart grid. When you watch it in the movies, it may seem like just a toy. However, designers are seriously thinking about their use, for example, in the factories of the future, where they will be busy producing small elements on a belt. work at home work in pa  

The advantage of this solution, developed by the SRI International research center, is that no power cords are required. Programmed to work in a swarm, they can, for example, assemble small device components or assemble electronic circuits. Their movements are controlled by boards with printed electronic systems and embedded systems of electromagnets on which they move. The microrobots themselves need only relatively cheap magnets.

The materials that these little workers can work with are glass, metals, wood, and electronic circuits.

Here is a video showing their capabilities:
