# Engineering notes (canonical)
|
||
|
||
Companion to `README.md` and `/documentation`. Not a stage changelog.
|
||
|
||
## Coordinate conventions
|
||
|
||
- World units: **1 unit = 1 meter**.
|
||
- Belt travel primarily along **+X**; belt top Y ≈ **0.70 m**.
|
||
- Lateral: **+Z** = physical LEFT (category C), **−Z** = physical RIGHT (category D).
|
||
- Sorter CAD module origin X = `0`; camera module `−2.01`; clean module `−4.02`.
|
||
- Longitudinal plane S for diverter timing is world X along the sorter module.
|
||
|
||
## Canonical constants (code)
|
||
|
||
| Symbol | Value | File |
|
||
|---|---|---|
|
||
| `DIVERTER_LEFT_SIGNED_DEG` | −45 | `src/domain/pusherMotion.ts` |
|
||
| `DIVERTER_RIGHT_SIGNED_DEG` | +45 | same |
|
||
| `rotationDurationSec()` | 0.50 | same (45° / 90°/s) |
|
||
| `OPENING_SAFETY_MARGIN_SEC` | 0.15 | same |
|
||
| Contact / clear planes | ≈1.0538 / 1.6000 | `buildDiverterPlanes` + mount hinge |
|
||
| Classifier min/max | exclusive 10³ / 450×320×320 | `src/domain/classifier.ts` |
|
||
| Roundness | K > 0.8 | same |
|
||
| `CONVEYOR_CAD_URL` | `/models/sorter/conveyor-clean.glb` | `ConveyorCadModel.tsx` |
|
||
|
||
## Active source tree (runtime)
|

```

src/main.tsx
|
||
src/App.tsx
|
||
src/pages/{MainPage,DocumentationPage}.tsx
|
||
src/components/{AppNav,SorterScene,CVInspectionOverlay,BuildIdentityBadge}.tsx
|
||
src/components/ThreeD/* (active twin only)

|
||
## Asset provenance
|
||
|
||
| Role | Path |
|
||
|---|---|
|
||
| Author CAD | `3d_models/conveer.FCStd` |
|
||
| Runtime conveyor | `public/models/sorter/conveyor-clean.glb` |
|
||
| Products | `public/models/*.stl` from official STL ZIP |
|
||
| Classifier PDF | `official_sources/doc-1783095831.pdf` |
|
||
| Workspace / scoring PDFs | `input_info/doc-1783009942.pdf`, `doc-1783011400.pdf` |
|
||
|
||
## Physics roadmap (not completed)
|
||
|
||
1. Surface-velocity belt at 1 m/s with visual loop.
|
||
2. Contact-validated CAD diverter deflection for all playlist SKUs.
|
||
3. Calibrated per-SKU mass, COM, friction, damping.
|
||
4. Receiver capture verification under dynamic drops.
|
||
|
||
CCD for light/thin items exists in runtime/sim; that alone is **not** full contact validation.
|
||
|
||
## Compliance evidence rules
|
||
|
||
- Prefer present official files under `input_info/` and `official_sources/doc-1783095831.pdf`.
|
||
- Missing: `input_info/extracted/Постановка_Задача_3_сжато_2.pdf` — never claim it is available.
|
||
- Internal engineering criteria are not automatic Ozon pass/fail.
|
||
|
||
## Соответствие подтверждённым требованиям
|
||
|
||
Grounded only in present sources + current `main` code/tests (not a full official scorecard):
|
||
|
||
| Area | Official source present | Current implementation | Evidence | Status |
|
||
|---|---|---|---|---|
|
||
| B/C/D bounds & roundness | `official_sources/doc-1783095831.pdf` | web `classifier.ts`, CV `cv/classify.py` | unit tests | PARTIAL (PDF not re-parsed each pass) |
|
||
| Digital twin demo | workspace PDFs in `input_info/` | `/` + `/documentation` | e2e smoke/routes, production | PASS (demo present) |
|
||
| CAD conveyor | author pack / STL references | `3d_models/`, `conveyor-clean.glb` | checksums in README | PASS (assets present) |
|
||
| Real measurement CV | Track 3 camera intent in briefs | `cv/` RealSense+OpenCV | `cv/README.md`, `test_classify.py` | PARTIAL (prototype, not live web) |
|
||
| Physical industrial line | scoring/workspace PDFs | web physics + optional MQTT CV | code; contact not fully validated | PARTIAL |
|
||
| Presentation / video | platform rules | cloud links | README §17 | NOT_VERIFIED (links missing) |
|
||
|
||
## Real CV prototype
|
||
|
||
Path `cv/` — OpenCV + RealSense D415 depth pipeline. Same B/C/D domain as the web twin. **Not** consumed by https://arhipovdan.ru. Details: `cv/README.md`.
|
||
|
||
## Layout drawing
|
||
|
||
`docs/engineering/work-area-layout-source.png` — workspace layout provenance image retained for engineering reference.
