When it comes to building robots, most of us use motors. It is also possible to build them with metamaterials that bend, twist, and change shape to move. Metabot by Princeton researchers can be controlled with a magnetic field. It is a modular set of reconfigurable unit cells that are “mirror images of each other” (called chiarlity). It can twist, contract, and shrink.

Tuo Zhao, an author of the paper, created a metabot that was 100 microns in height. In the future, this approach can be used to build robots to deliver medicine to various parts of the body. The researchers were inspired by the origami structures to build this.
