Not nano yet, but already micro
A group of scientists from Carnegie Mellon University in Pittsburgh (USA) develops tiny robots that can connect with each other and thereby take an arbitrary shape.

The essence of the project is the use of electromagnetic or electric forces to unite small-sized robots into groups. In early experiments, scientists used cylindrical “typewriters” with electromagnets placed on their housings. The wheels of these robots were not equipped with any drives, and therefore, when maneuvering, the devices relied solely on electromagnetic forces.

Later prototypes of mini-robots are made in the form of cubes, equipped with six “legs” with tips in the shape of a star. Each of these stars contains several aluminum electrodes and may have a positive or negative charge. Robots are connected to each other using static forces.
The main difficulty is the writing of specialized software for communicating with schools of robots and coordinating their actions. Scientists simply do not know how to create such a program. Accordingly, it is too early to talk about the practical use of microrobots.
