We are still far removed from the point where LEGO robots can build copies of themselves, but the ‘Fabrik Mosaïque’ built by minkowsky shows an interesting first step.
The factory building itself is nice, but when I first saw it, it didn’t strike me as all that remarkable. I’m glad I took a closer look, however, because of what it does: using LEGO Mindstorms it scans an image and then produces an 8 x 8 pixel two colour mosaic of that image using lines of LEGO tiles.
I can’t quite see a factory like this appearing in every shopping district and I wonder how well it does with an image that isn’t pixelated to start with, but this is clever stuff.
