AI-Powered LEGO Robot Builds Pixel Portraits

With over 17 years of writing experience, Jonathan has had a passion for all things tech-related, ever since watching Inspector Gadget as a child. He's disassembled countless appliances and managed to put a few back together, and one still works. When not writing, he can often be found playing video games or accidentally hurting himself in the garage.

Built by Dutch creator Sten of the YouTube channel Creative Mindstorms, the AI LEGO PixelArt Robot (aka PixelBot 3000) is a LEGO robot that can build pixel-style portraits with 1×1 LEGO studs using text prompts. You simply type in a subject, and the AI art program DALL-E 3 generates an image. Then, Sten’s custom Python code transforms it into a piece of pixel art capable of fitting on a 32 x 32 baseplate. PixelBot, build me the Mona Lisa!

The robot can use up to 15 colors to create its portraits, with 1×1 studs fed to it from a vertical hopper, which does require human refilling if a color gets low. PixelBot creates its pictures line by line, with a corkscrew mechanism automatically moving the baseplate when it’s time to start a new line.

It’s a pretty impressive feat of programming and engineering. How people can develop and execute these builds never ceases to amaze me. And all in their own spare time! I couldn’t even do this if I was getting paid good money to.
