Robots could assemble themselves into ARMIES: New material could lead to swarms of machines that act as a single-minded unit

A new material has been created that can self-assemble into a swarm, acting as a single-minded unit.

The material, which is made up of a set up spheres, is able to automatically arrange into a pattern when exposed to an electric field.

In the future, this could be used to create armies of robots that act as a relentless, single-minded unit.
