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 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.
Live now: every one drivable.
Each design's sim twin is live: drive it in real MuJoCo physics, then take the same commands to hardware. Cheapest and most community-ready first.
The CyberBrick Rover
One printed body, one board of your choosing, one policy, proven end to end. Drive the twin now, then take the same code to real hardware. This is the smallest complete loop in Physical AI.
● Twin liveQuadruped · from ~$140The Printed Quadruped
The iconic Physical AI form: a twelve-servo legged dog you print at home. A central-pattern-generator turns a stick into a stable trot, the same gait you'll port to the servos.
● Twin liveUAV · from ~$110The FPV Drone
A perception-driven quadrotor: a printed frame, a real flight controller for stabilization, and a brain for the policy. Fly the twin first, in real rigid-body physics.
● Twin liveAquatic · from ~$120The Reef AUV
A free-swimming underwater vehicle: near-neutral buoyancy, six degrees of freedom, and a floaty momentum you learn to anticipate. Pilot the twin through a reef before you waterproof a thing.
● Twin liveManipulator · from ~$90The Printed Arm
The workhorse of Physical AI: a fixed-base arm that picks a block and places it on a target. Real datasets, real imitation learning, the platform behind the checkpoint and VLA courses.
● Twin liveIn the shop
Soft grippers, sensor rigs, and the odd hybrids you invent are next, each brain-agnostic and sim-twinned, landing as it's verified.
