|
| - **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. |
