The Pixelbot 3000 turns easy AI prompts into Lego mosaic masterpieces

A faithful YouTuber has designed and built a Lego printer that may automate the method of assembling elaborate brick-built mosaics, much like Lego’s artwork units like da Vinci’s Mona Lisa or Hokusai’s The Great Wave. However whereas the creation attracts inspiration from one other Lego printer referred to as the Bricasso, it streamlines the method utilizing AI.

Though technically spectacular when it debuted eight years in the past, Jason Allemann’s Bricasso required a sophisticated course of the place mosaic designs needed to be manually created, printed on paper, after which scanned by the machine’s digital camera. The YouTube channel Creative Mindstorms used some customized code and AI, so producing a Lego mosaic requires one easy enter.

With the Pixelbot 3000, customers merely should sort in what paintings they need the printer to create. The immediate is distributed to OpenAI’s DALL-E 3, which the underlying code requests as being generated in a cartoon type to provide a simplified picture that’s 1024 x 1024 pixels in measurement.

The mosaics assembled by the printer are restricted to a a lot smaller grid that’s simply 32 x 32 Lego tiles in measurement, however as an alternative of resizing the picture generated by DALL-E 3 to make it smaller, the Pixelbot 3000’s code divides the AI-generated picture right into a 32 x 32 grid and samples the colour of the middle pixel in every sq.. This ends in a high-contrast scaled picture that produces a greater mosaic in the long run.

One other limitation imposed through the use of Lego as a creative medium is that the plastic bricks are solely obtainable in about 70 completely different colours, and the Pixelbot 3000 makes use of simply 15 of them. The scaled AI-generated picture requires one closing go to seek out the closest match of every coloured pixel to the 1 x 1 Lego tiles used to assemble the ultimate mosaic.

Designing, constructing, and programming the Pixelbot 3000 looks like it could be simply as a lot work as assembling considered one of Lego’s mosaic artworks, which can be over 11,000 pieces in measurement. When you’re actually seeking to de-stress, simply take quarter-hour and watch Inventive Mindstorms’ course of because the Pixelbot 3000 goes from an idea to a useful actuality.
