Meet the Duco robot: an autonomous electronics fabrication robot that enables room-scale circuitry to make everyday surfaces interactive. As the researchers explain, Duco
achieves single-layer or multi-layer circuit fabrication on 2D surfaces as well as 2D cutouts that can be assembled into 3D objects by loading various functional inks  to the wall-hanging drawing robot, as well as employing an optional laser cutting head as a cutting tool.
As the above video shows, this robot can be used to turn a wall into a musical instrument or smart home controller.
