No CAD, no code — still build a machine that really moves. Hardware has nine cells that can fail (idea / prototype / product × 3D / electronics / software); any one blocking cell stalls the whole thing — 3C compresses all nine into one.
Construct · what to buildAssemble a mechanism like building blocks. Joints carry their own constraints — wrong connections don't fit; right ones really move.
Cube · what to plug inTurns electricity into motion, and the world into numbers. In simulation, drag it in and it works; on a real board you wire it to the pins shown on its card.
Code · what to doSay a sentence → AI generates blocks; drag blocks → compiles to a program. No programming background needed.
Drag in a mechanism — pick from 667 in the library, or upload your own
Drag a cube onto it — put it anywhere; move it and the reading changes
Drag blocks, or pick a preset — one program per board; blue reads, red writes
▶ Run in simulation — the same program exports as board code (proven end-to-end for distance, buzzer and screen so far)
Two engines cross-checked: the browser runs kinematics; MuJoCo is the second ruler — on the same car it only let it travel about half as far, so simulation alone isn't the final word. MK: proven in simulation, built by hand. MK Pro: the same three C's unchanged, plus a fourth — C₄ Calibrate — to get the machine standing on real ground.
