## Overview

Agents that work in a chemistry lab need more than meshes. They need to know that a fume-hood sash travels 673 mm and
stops at 457 mm, that moving a balance's draft-shield door restarts its stability check, and which quantities a policy
may observe and which are hidden ground truth kept for evaluation. ChemLab-Assets ships that knowledge with the geometry.

Each asset is one specific commercial instrument, chosen from a survey of 200 instruments and modules used in university
chemistry teaching and research, and built from published brochures, manuals and papers. The models reproduce documented
behaviour; they are not manufacturer CAD and have not been calibrated against physical units.

This dataset holds everything: models, contracts, runtimes, tests and the catalog. The code is mirrored on [GitHub](https://github.com/mbzuai-nlp/ChemLab-Assets); see also the [Project website](https://mbzuai-nlp.github.io/ChemLab-Assets/).

## Request an instrument

Missing an instrument from your lab? [Open an instrument request](https://github.com/mbzuai-nlp/ChemLab-Assets/issues/new?template=instrument_request.yml) and tell us the maker and model.
Manuals, brochures, photos from several sides and a few lines on how you use it help us build an accurate model.
Please only attach files you are allowed to share; for the manufacturer's public documents a link is enough.

## Quick start

**1. Get the data.** Everything (about 1.5 GB), or one instrument plus the code:

```bash
pip install -U huggingface_hub
hf download MBZUAI/ChemLab-Assets --repo-type dataset --local-dir ChemLab-Assets
pip install -r ChemLab-Assets/requirements.txt   # NumPy 2.0–2.3, SciPy, Pillow, OpenCV, CoolProp, pytest

hf download MBZUAI/ChemLab-Assets --repo-type dataset --local-dir ChemLab-Assets \
    --include "assets/expansion_batch05/t2_vacuum/esco_efa5uduvw/*" "scripts/*" "examples/*"
```

`catalog/catalog.csv` gives every instrument's folder, so any subset can be fetched the same way. Run the test suite
with `python -m pytest` from the dataset root (tests that re-hash cached third-party source files skip themselves,
because those files are not redistributed).

**2. Run an instrument.** The fume hood below starts with an uncalibrated airflow monitor. The robot raises the sash,
sees a low reading, measures the opening with an anemometer and calibrates the monitor. It never sees the true face
velocity (0.299 m/s), which is an evaluator-only slot. Full script: [`examples/quickstart_fume_hood.py`](examples/quickstart_fume_hood.py).

```python
from asset_runtime import esco_efa5uduvw as rt   # run from the repo root with scripts/ on sys.path

hood = rt.EscoEfa5uduvwRuntime("hood_01")
hood.register_principal("lab", "evaluator")    # sets up the world, sees hidden truth
hood.register_principal("robot", "agent")      # sees what a policy may see
lab, robot = hood.session("lab"), hood.session("robot")

call(lab, "plant.configure", **rt.PLANT_EXAMPLE)        # 295.15 K, 101.325 kPa
call(lab, "exhaust.configure", **rt.EXHAUST_EXAMPLE)    # building exhaust, damper half open
call(robot, "sash.set", height_m=0.457)                  # raise to the 18-inch stop
call(lab, "sim.step", dt_s=30.0)
show("before calibration")

v = call(robot, "anemometer.measure")["face_velocity_m_s"]
call(robot, "monitor.calibrate", reference_m_s=round(v, 3))
call(lab, "sim.step", dt_s=10.0)
show("after calibration")
```

```text
before calibration   reading 0.28 m/s   alarm low
anemometer           0.309 m/s
after calibration    reading 0.31 m/s   alarm none
```

**3. Load it in a simulator.** URDF mesh paths are relative, so any URDF loader works from the asset folder. All 203
URDFs load with [yourdfpy](https://github.com/clemense/yourdfpy):

```python
import yourdfpy
hood = yourdfpy.URDF.load("assets/expansion_batch05/t2_vacuum/esco_efa5uduvw/model.urdf")
hood.update_cfg({"sash_joint": 0.45})   # raise the sash 450 mm
hood.show()
```

For Isaac Lab, convert `model.urdf` with the Isaac Lab URDF importer. GLB files keep the Z-up asset frame; rotate −90° about
X in Y-up viewers (the catalog's `glb_up` column says which files need it).

## What an asset contains

```text
assets/expansion_batch05/t2_vacuum/esco_efa5uduvw/
├── asset.contract.json      # the contract: components, joints, state slots, capabilities, sources, limitations
├── model.glb                # viewing (asset frame: Z up, front faces −Y)
├── model.urdf               # simulators: links, joints with limits, primitive collision proxies
├── meshes/                  # one OBJ + MTL per functional part (78 files here)
├── textures/                # panel, label and screen textures drawn for the model
├── model.blend              # Blender source with named parts
├── geometry_manifest.json   # parts, frames, dimensions and joint layout
├── collision_proxies.json   # primitive colliders per part
├── instrument_model.json    # runtime parameters (this instrument)
├── vapour_templates.json    # reference data used by the runtime (53 vapour sources)
└── 说明.md                  # notes on the model and its data (Chinese)

scripts/asset_runtime/esco_efa5uduvw.py   # the behaviour runtime
tests/test_asset_esco_efa5uduvw.py        # its tests
```

The contract is the centre of each asset. It names every functional **component** and binds it to meshes and colliders;
lists **state slots** with type, unit, range, origin (setpoint, sensor, derived, process truth) and visibility (agent,
evaluator, debug); defines **capabilities** with JSON-Schema arguments, preconditions, state effects, declared errors and
a verification level for process, host, scene, robot and hardware; and records **mechanisms**, **ports**, **sources** and
**limitations**. The specification is in [`skills/chemistry-lab-assets/references/contract.md`](skills/chemistry-lab-assets/references/contract.md)
and the call protocol in [`protocol.md`](skills/chemistry-lab-assets/references/protocol.md) (both in Chinese); the
validator is `skills/chemistry-lab-assets/scripts/asset_tool.py`.

## Provenance, licences and limits

* **Sources.** Each state slot and capability lists the sources it rests on: manufacturer documents for dimensions,
  ranges and limits; papers, standards and open databases for the measurements behind instrument outputs; explicit
  assumptions where neither exists. Raw third-party documents (PDF manuals, brochures, application notes, papers,
  spectra files, photos) are not redistributed; contracts keep the citations and derived values.
* **Licences.** Code is MIT ([`LICENSE`](LICENSE)). Models, contracts and data are CC BY-NC 4.0
  ([`LICENSE-ASSETS.md`](LICENSE-ASSETS.md)). Some data files carry their source's terms (CC BY-SA, non-commercial, or
  rights reserved by the publisher); [`NOTICE.md`](NOTICE.md) lists every one with its source.
* **Trademarks.** Product and company names identify the modelled instrument only. This project is not affiliated
  with or endorsed by any manufacturer.
* **Limits.** 804 capabilities are declared but marked unsupported. No capability claims robot-contact or
  real-hardware validation. Treat the assets as documented, testable behaviour models for embodied-AI research, not
  as certified digital twins.
* **Build records.** Contracts list the files of the original build (validation logs, review records, cached source
  documents). Those are not part of the release; `release_manifest.json` says which artifacts ship.

## To-Do List

- [x] Real reference data for every instrument that measures samples (v1.1)
- [x] Shared compound table linked to the instruments (v1.1)
