The minuscule house features a tiled roof, seven windows, a door and a teensy chimney. It was created at the Femto-ST Institute in Besançon by a robot controlling a tightly focused beam of charged particles known as ions.
The micro-dwelling was built inside a vacuum chamber to demonstrate the dexterity and precision of the team’s robotic system. But the project was more than just a chance to show off. The scientists say the capability to create such intricate nanostructures could one day transform industries ranging from aerospace to medicine.
