Microrobot (IMAGE) Paul Scherrer Institute Caption The scanning electron microscope image shows the bird-like construct with arrangements of nanoscale magnets. The magnets can be magnetised in different orientations parallel to the colour bars. By programming their magnetisation, the researchers can make bird carry out different movements in a magnetic field.
