MIT prof runs 3 Grok bots: 4 images in, 3D-printed objects out — end to end

MIT professor Markus Buehler demonstrated an end-to-end multi-agent engineering experiment:

Task: three Grok bots took four reference images as design cues to solve a complex engineering problem
Pipeline: infer transferable structural principles from pixels → synthesize an executable interactive physics simulator → run 47 simulation experiments (six holdouts) → reject the initial hypothesis → select optimal designs, slice them, and send to a 3D printer
Supervision: Buehler coordinated the entire loop from an Apple Watch, including a Chief-of-Staff bot orchestrating the workflow

The whole loop worked remarkably well, going from image input to real physical manufacturing in one pass.
