Google Carbon builds a 60-second Rube Goldberg machine with CUDA path tracer and MuJoCo
AI_Andrew · x · 2026-11-11
- A demo shows Google's Carbon model completing a long-horizon engineering task: writing a custom CUDA/C++ path tracer from scratch and integrating MuJoCo rigid-body physics.
- Carbon designed and tuned a 60-second Rube Goldberg machine, running 120,000 gravity and contact steps in MuJoCo with no keyframes.
- It also built a 3D studio scene and synced a continuous camera take to a custom Lyria 3.5 track.
- Commenters verified the MuJoCo contact steps; a showcase of long-horizon coding and multi-tool orchestration.
