Things to make — from a printer and a board.
Every build here is the same recipe made concrete: a printable body, a recommended brain (sized to the job, never locked to one), its sim twin to train against, and a real policy to run. Start cheap, then climb.
UAVs, rovers, aquatic drones, humanoids — and everything in between.
UAVs
Multirotors and fixed-wing craft that fly on perception, not just radio.
Rovers
Wheeled and tracked robots that navigate, avoid, and manipulate.
Aquatic drones
Surface boats and underwater vehicles for a buoyant, 6-DOF world.
Humanoids
Bipeds and arms — balance and dexterity, the general-purpose form.
Quadrupeds
Four-legged walkers, the iconic Physical AI gait.
Everything between
Grippers, soft robots, sensor rigs, and the odd hybrids you invent.
Four parts, brain-agnostic.
No design forces a single board. Each one names a recommended brain per budget — a few-dollar microcontroller for the cheap path, an edge-AI module when the policy is heavy.
Printable body
STLs and a bill of materials — Bambu / MakerWorld-anchored, printable on any FDM machine.
Recommended brain
A sized suggestion from Digital Brains — cheap, mid, and heavy options, never one lock-in.
Sim twin
The matching in-browser physics model, so you design and train before you print.
A policy to run
A real Physical AI model to drive it — ours to start from, or the one you train yourself.

The first design is drivable in your browser this second: write a policy, run it in real MuJoCo physics, then take it to hardware. Cheapest and most community-ready first.
The CyberBrick Rover
The cheapest end-to-end build: a printed two-motor rover, a brain-agnostic board (CyberBrick, ESP32, or Pi), a drivable sim twin, and a policy you write and run right on the page.

Quadruped, FPV drone, aquatic surface rover, and a printed arm are next — each brain-agnostic and sim-twinned, landing as it's verified end to end.
