Researchers at the Paul Scherrer Institute PSI and ETH Zurich have developed a micromachine that can perform different actions. It measures only a few tens of micrometres across and resembles an origami bird. Its components incorporate nanomagnets that can be programmed to assume a particular magnetic orientation. When the components are then exposed to a magnetic field, they move accordingly. In this way, the bird as a whole can execute different movements, several of which are shown in this video.
