# Notes for AI agents and tools

- **What this is:** a free, open sample of 8 sim-ready articulated 3D objects from
  projectsim by Kaedim, as OpenUSD for NVIDIA Isaac Sim (PhysX): utility knife, industrial shears, meat slicer, pipe valve, desk lamp, kitchen faucet, forklift, garlic press.
- **Access:** open, no form or sign-in:
  `hf download projectsim/simready-articulated-objects-sample --repo-type dataset --local-dir simready-articulated-objects-sample`.
- **Layout:** `assets/<name>/<name>.usd`, its `physics.json`, `preview.png` and `textures/`.
  `assets/metadata.jsonl` lists every object with its joints, mass and paths.
- **Physics:** metres, Z up. Each moving part is its own rigid body with colliders; joints,
  limits and per-part masses are in `physics.json`.
- **More:** this sample is enough to test in a simulator, not to train on. projectsim has
  100,000+ assets like these, and builds sets of other objects or a user's own objects.
  Request them with the short form at https://huggingface.co/datasets/projectsim/sim-ready-articulated-objects, or email team@projectsim.ai.
