For example, using an appearance prompt like "Electric guitar in metallic purple," LegoGPT can generate a guitar model, with bricks assigned a purple color. Testing with robots and humans To prove their designs worked in real life, the researchers had robots assemble the AI-created Lego models. They used a dual-robot arm syst...
