-# Структура репозитория:
+# OZON Sorter Digital Twin
+
+Complete Track 3 Ozon Tech solution in one repository: a web digital twin of the sorting line, plus a real RealSense/OpenCV CV prototype.
+
+**Production:** https://arhipovdan.ru
+
+## 1. Overview
+
+This repository delivers a continuous web simulation of an Ozon conveyor sorter: CAD conveyor, product models, camera/measurement stage, B/C/D classification, diverters, and Rapier physics. The public demo runs on https://arhipovdan.ru with routes `/` (simulation) and `/documentation` (engineering status).
+
+Separately, `cv/` contains a **working hardware prototype** that reads Intel RealSense D415 depth, measures parcels with OpenCV, classifies B/C/D, and can publish results over MQTT. It is **not** wired into the live website.
+
+Both paths share the same Track 3 classification domain (exclusive 10×10×10 … 450×320×320 mm, roundness K > 0.8). The web twin uses a digital sensor simulation; the CV folder uses real depth frames.
+
+`main` is the canonical complete solution. Developers do not need other branches to run the web app or inspect/run the CV prototype.
+
+Large submission artifacts (presentation, video, optional CAD/model mirrors) belong in team cloud storage; runtime assets required by deploy stay in Git.
+

-Тут находится простой python скрипт для управления шагововым двигателем по средствам последовательных команд.
+No other top-level product directories are required to run or understand the solution.

-## Папка kicad 
+## 8. Requirements

-Тут будут находится электрические схемы проекта
+**Web:** Node.js 20+, npm (`package-lock.json`).
+**CV:** Python 3.10+, ffmpeg, V4L2; RealSense D415 for live mode (`cv/requirements.txt`).
+**Hardware (CV live / MQTT):** D415 USB3; optional MQTT broker + servo/motor controllers on site network.

-## Папка specification
+## 9. Web quick start

-В этой папке разрабатывается спецификация на проект
+```bash
+npm ci
+npm run dev          # http://127.0.0.1:3100
+npm test -- --run
+npm run build
+npm run preview      # http://127.0.0.1:3100
+```
+
+## 10. CV quick start
+
+```bash
+cd cv
+./demo.sh            # venv + deps; HUD on :8080 (needs D415 for live view)
+# without camera:
+python3 -m venv .venv && .venv/bin/pip install -r requirements.txt
+.venv/bin/python test_classify.py
+.venv/bin/python test_geometry.py
+# live pipeline (hardware):
+./run.sh --preview --no-mqtt --no-motor
+```
+
+`npm install` does **not** install CV dependencies.
+
+## 11. Configuration
+
+**Web (build-time, optional):** `VITE_BUILD_COMMIT`, `VITE_BUILD_BRANCH`, `VITE_BUILD_RELEASE` → `/version.json`. No runtime secrets.
+
+**CV:** copy `cv/config.example.yaml` → `cv/config.yaml` (gitignored). MQTT/motor/routing **disabled by default**. Never commit real passwords or broker credentials.
+
+## 12. Classification rules
+
+Verified in web (`src/domain/classifier.ts`) and CV (`cv/classify.py`):
+
+- dimensions strictly **> 10×10×10 mm** and **< 450×320×320 mm**
+- circular when **K > 0.8** (web) / `circle_ratio ≥ 0.8` (CV)
+- order: dimensions fail → **C**; else circular → **D**; else **B**
+
+Official citation: `official_sources/doc-1783095831.pdf` (present; not re-parsed on every doc pass). Missing extracted brief PDF is not claimed.
+
+## 13. Physics (accepted `main`)
+
+From current source (not superseded experimental branches):
+
+- belt speed **1.0 m/s** (`CONVEYOR_SPEED_MPS`)
+- fixed timestep **1/60 s** (`PHYSICS_TIMESTEP_SEC`)
+- CCD for light/thin product bodies
+- diverters LEFT **−45°**, RIGHT **+45°**
+- full contact-only junction sorting through CAD: **not fully validated**
+
+## 14. CAD and assets
+
+| Asset | Path |
+|---|---|
+| Author CAD | `3d_models/conveer.FCStd` |
+| Runtime GLB | `public/models/sorter/conveyor-clean.glb` |
+| Products | `public/models/*.stl` |
+
+Keep runtime assets in Git for deploy. Mirror large CAD/models/presentation/video to cloud for submission.
+
+SHA-256 (frozen):
+
+```
+3d_models/conveer.FCStd
+90c1844a4ca05e26def783d6130fc4b993430dde14307534ef8fbb21c9fac2e6

+public/models/sorter/conveyor-clean.glb
+1dc7a8d7891bfe756e277ad5368df74cb73410156b2fe0f92845afb8a56f285a
+```
+
+## 15. Testing
+
+```bash
+npm test -- --run
+# current release result: 196/196
+npm run build
+PLAYWRIGHT_BASE_URL=http://127.0.0.1:3101 npm run test:e2e -- e2e/routes.spec.ts e2e/smoke.spec.ts
+
+cd cv && .venv/bin/python test_classify.py && .venv/bin/python test_geometry.py
+```
+
+## 16. Deployment
+
+Nginx terminates TLS for `arhipovdan.ru` and proxies to Docker `owl-web-1` (`docker-compose.server.yml` + `Dockerfile`) on `127.0.0.1:3100`. Deploy from `main` with build-args for `/version.json`. CV is **not** part of the web container.
+
+## 17. Submission materials
+
+| Material | Status |
+|---|---|
+| Presentation URL | REQUIRED_FROM_OWNER |
+| Video demo URL | REQUIRED_FROM_OWNER |
+| Cloud folder URL | REQUIRED_FROM_OWNER |
+
+Do not invent links. Runtime site assets remain in Git even when mirrored to cloud.
+
+## 18. Known limitations
+
+- Mobile uses 2D lite fallback on current baseline
+- CV is a prototype and is not live-integrated into arhipovdan.ru
+- Simulation physics is engineering-derived; hardware calibration still required
+- Contact routing through CAD diverters not fully validated
+- Large presentation/video must be uploaded to cloud by owner
+
+## 19. Branch history policy
+
+**`main` is the canonical complete solution** (web + cleaned CV under `cv/`). Historical branches (`dan_branch`, `drho1y-mvp_1`, …) may remain for audit but are not required to run the product.

-
-## 📌 Общая информация
- **Архитектура**: ESP32 (FreeRTOS задача `mqttTask`).
- **Период опроса телеметрии**: 500 мс.

-This directory is intended for project header files.
-
-A header file is a file containing C declarations and macro definitions
-to be shared between several project source files. You request the use of a
-header file in your project source file (C, C++, etc) located in `src` folder
-by including it, with the C preprocessing directive `#include'.
-
-```src/main.c
-
-#include "header.h"
-
-int main (void)
-{
- ...
-}
-```
-
-Including a header file produces the same results as copying the header file
-into each source file that needs it. Such copying would be time-consuming
-and error-prone. With a header file, the related declarations appear
-in only one place. If they need to be changed, they can be changed in one
-place, and programs that include the header file will automatically use the
-new version when next recompiled. The header file eliminates the labor of
-finding and changing all the copies as well as the risk that a failure to
-find one copy will result in inconsistencies within a program.
-
-In C, the convention is to give header files names that end with `.h'.
-
-Read more about using header files in official GCC documentation:
-
-* Include Syntax
-* Include Operation
-* Once-Only Headers

-This directory is intended for PlatformIO Test Runner and project tests.
-
-Unit Testing is a software testing method by which individual units of
-source code, sets of one or more MCU program modules together with associated
-control data, usage procedures, and operating procedures, are tested to
-determine whether they are fit for use. Unit testing finds problems early
-in the development cycle.

+# Real CV prototype — RealSense D415 + OpenCV
+
+**Status:** WORKING_PROTOTYPE
+**Production integrated:** NO (https://arhipovdan.ru does **not** consume this pipeline)
+**Source:** consolidated from branch `drho1y-mvp_1` (`vision_classifier/`) into `cv/`
+
+Same Track 3 B/C/D rules as the web twin; different input path (real depth camera vs simulated sensor).
+
+## Purpose
+
+Measure parcels on a conveyor with an Intel RealSense D415 (depth + color), estimate L×W×H and circularity, classify into zones **B / C / D**, optionally publish results over MQTT for hardware routing.
+
+## Data flow
+
+```
+RealSense D415 (V4L2 depth + color)
+  → OpenCV segmentation on depth (optional RGB flat detect)
+  → measure L×W×H + circle_ratio
+  → stabilize (median / vote → LOCK)
+  → classify B/C/D
+  → optional MQTT (category, dimensions, servo/motor topics)
+```
+
+## Entrypoints (start here)
+
+| Command | Role |
+|---|---|
+| `./demo.sh` | Browser HUD demo on `:8080` (needs camera for live view) |
+| `./run.sh --preview` | Live pipeline with JPEG preview frames |
+| `./run.sh --once --no-mqtt --no-motor` | Single-shot / dry hardware |
+| `.venv/bin/python test_classify.py` | Classifier unit checks **without camera** |
+| `.venv/bin/python test_geometry.py` | Geometry helpers **without camera** |
+
+Primary modules: `main.py` (live), `demo.py` (HUD), `classify.py` (rules), `measure.py` (depth metrics), `camera.py` (V4L2 RealSense).
+
+## Classification rules (Track 3)
+
+1. Dimensions must be strictly **> 10×10×10 mm** and **< 450×320×320 mm** → else **C**
+2. Else if `circle_ratio ≥ 0.8` → **D**
+3. Else → **B**
+
+Stabilization: median window + vote → **LOCK**. Uncertain cases fall back to zone **C** after N frames.

+cp config.example.yaml config.yaml   # optional; scripts auto-copy
+```
+
+Or simply:
+
+```bash
+cd cv
+./demo.sh          # creates .venv and config.yaml on first run
+```
+
+## Demo / tests without claiming live camera
+
+Classifier and geometry (no RealSense required):
+
+```bash
+cd cv
+python3 -m venv .venv && .venv/bin/pip install -r requirements.txt
+.venv/bin/python test_classify.py
+.venv/bin/python test_geometry.py
+python3 -m compileall .
+```
+
+Live HUD (requires D415):
+
+```bash
+./demo.sh
+# open http://127.0.0.1:8080/
+```
+
+Live pipeline:
+
+```bash
+./run.sh --preview --no-mqtt --no-motor
+# or full hardware once MQTT/routing configured in local config.yaml:
+./run.sh --preview
+```
+
+## Configuration
+
+| File | Role |
+|---|---|
+| `config.example.yaml` | Committed safe defaults; **MQTT/motor/routing disabled** |
+| `config.yaml` | Local overrides — **gitignored**; never commit credentials |
+
+Optional MQTT (enable only locally):
+
+```yaml
+mqtt:
+  enabled: true
+  broker: "127.0.0.1"
+  port: 1883
+  user: "<your-user>"
+  password: "<your-password>"
+```
+
+CLI overrides: `--no-mqtt`, `--no-motor`, `--dry-route`, `--once`, `--preview`.
+
+## Output schema (LOCK)
+
+- Zone: `B` | `C` | `D`
+- Dimensions mm: L×W×H
+- `circle_ratio`
+- Optional MQTT topics (when enabled): `vision/feedback/category`, `…/dimensions`, `…/circle_ratio`
+- Optional JSONL: `logs/decisions.jsonl` (local, gitignored)
+
+## Limitations
+
+- Not connected to the web digital twin runtime.
+- Requires calibrated intrinsics / belt height for accurate mm.
+- Live demo needs a physical D415; CI hosts usually lack it.
+- MQTT/servo/motor path is optional and site-specific.
+
+## Troubleshooting
+
+| Symptom | Check |
+|---|---|
+| No `/dev/video*` | USB3, `lsusb`, `v4l2-ctl --list-devices` |
+| Depth empty | ffmpeg installed; correct `depth_device` |
+| Wrong sizes | run `calibrate.py --length … --width …` |
+| MQTT offline | expected when `mqtt.enabled: false` |
+
+## Relation to web twin
+
+Web (`src/domain/classifier.ts`) and CV (`classify.py`) implement the **same official bounds**. The public site uses a **digital sensor simulation**; this folder is the **hardware prototype** for future integration.

+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)

+## 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 |

+| 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`.

+# Draco 3D Data Compression
+
+Draco is an open-source library for compressing and decompressing 3D geometric meshes and point clouds. It is intended to improve the storage and transmission of 3D graphics.
+
+[Website](https://google.github.io/draco/) | [GitHub](https://github.com/google/draco)
+
+## Contents
+
+This folder contains three utilities:
+
+* `draco_decoder.js` — Emscripten-compiled decoder, compatible with any modern browser.
+* `draco_decoder.wasm` — WebAssembly decoder, compatible with newer browsers and devices.
+* `draco_wasm_wrapper.js` — JavaScript wrapper for the WASM decoder.
+
+Each file is provided in two variations:
+
+* **Default:** Latest stable builds, tracking the project's [master branch](https://github.com/google/draco).
+* **glTF:** Builds targeted by the [glTF mesh compression extension](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_draco_mesh_compression), tracking the [corresponding Draco branch](https://github.com/google/draco/tree/gltf_2.0_draco_extension).
+
+Either variation may be used with `DRACOLoader`:
+
+```js
+var dracoLoader = new DRACOLoader();
+dracoLoader.setDecoderPath('path/to/decoders/');
+```
+
+Further [documentation on GitHub](https://github.com/google/draco/tree/master/javascript/example#static-loading-javascript-decoder).

-# Алгоритм работы сортировщика
-
-```mermaid
-mindmap
-  root((Алгоритм работы))
-    Этап 1: Ожидание и Движение
-      Arduino запускает шаговый двигатель
-      Лента движется с постоянной скоростью
-    Этап 2: Детекция и Анализ
-      Объект проходит под датчиком и камерой
-      Предмет соответствует габаритам?
-        Да
-          Есть признак круга в сечении?
-            Да - Требуется доупаковка
-              Секция 2
-            Нет - Подходит для сортировки
-              Секция 3
-        Нет
-          Не подходит по габаритам
-            Секция 1
-    Этап 3: Трекинг Синхронизация
-      Arduino отсчитывает шаги двигателя
-      Вычисляется момент времени T
-    Этап 4: Маршрутизация
-      В момент T сервопривод поворачивает барьер на 45°
-      Объект смещается в выбранную зону
-      Сервопривод возвращается в исходное положение
-    Этап 5: Завершение
-      Объект попадает в накопитель
-      Система возвращается в состояние Ожидание

-Привет! Как инженер-конструктор и эксперт по электронике, я с удовольствием помогу тебе спроектировать этот макет. Задача ясна: создаем систему автоматизированной сортировки с точным управлением скоростью и маршрутизацией по высоте.
-
-Давай разберем твои вопросы по порядку.
-
-### 1. Выбор двигателя: Шаговый vs Коллекторный
-
-Для твоей задачи — **максимально точного выдерживания скорости** и управления с микроконтроллера — выбор очевиден.
-
-| Характеристика | Коллекторный двигатель (DC) | Шаговый двигатель (Stepper) |
-| :--- | :--- | :--- |
-| **Точность скорости** | Низкая. Скорость зависит от напряжения и нагрузки. Для точности нужен энкодер (обратная связь). | **Высокая**. Скорость задается частотой импульсов. Постоянна при заданной нагрузке. |
-| **Управление** | Простое (PWM/ШИМ). | Требует специальный драйвер (например, A4988 или TMC2208). |
-| **Пуск/Стоп** | Плавный разгон, сложно точно позиционировать. | **Идеальный**. Можно точно задать количество шагов и мгновенно остановиться. |
-| **Крутящий момент** | Высокий на высоких оборотах. | Высокий на низких скоростях (идеально для ленты). |
-| **Сложность реализации** | Очень низкая. | Средняя (нужен драйвер и настройка тока). |
-
-**Мой вердикт:** Используй **шаговый двигатель (например, NEMA 17)**. 
-Если ты хочешь «выдерживать скорость максимально точно», обычный DC-мотор тебя разочарует: при увеличении веса объекта на ленте скорость будет падать. Шаговый же двигатель будет поддерживать заданный темп, пока не будет достигнут предел его крутящего момента.
-
---
-
-### 2. Селекторы (Сервоприводы)
-
-Использование сервоприводов с барьером под 45° — это классическое и эффективное решение для макета. 
-
-**Советы по реализации:**
-*   **Механика:** Чтобы объект не застревал и не «зажевывался», сделай барьер обтекаемым или используй гладкий пластик/алюминий.
-*   **Угол:** 45 градусов — оптимально, но убедись, что при срабатывании сервопривод не толкает объект слишком резко, чтобы тот не перевернулся.
-*   **Логика:** В промышленном подходе, как отмечено в контексте, важно отслеживать «корректность маршрутизации» [1]. Рекомендую добавить в код проверку: действительно ли объект ушел в нужную зону, или произошла ошибка.
-
---
-
-### 3. Датчик определения высоты
-
-Для измерения высоты объекта сверху, когда лента движется, тебе подойдут три варианта в зависимости от требуемой точности:
-
-1.  **Ультразвуковой датчик (HC-SR04):** Самый дешевый и популярный. 
-    *   *Минус:* Широкий луч (может «цеплять» борта конвейера) и низкая скорость обновления.
-2.  **ИК-датчик расстояния (Sharp GP2Y0A21YK0F):** Более точный, узкий луч.
-    *   *Минус:* Аналоговый сигнал, чувствителен к цвету объекта (черный поглощает ИК).
-3.  **Лазерный ToF-датчик (VL53L0X / VL53L1X):** **Мой выбор для этого проекта.** 
-    *   *Плюсы:* Измеряет время полета фотона (Time-of-Flight), работает независимо от цвета объекта, очень высокая точность (до миллиметров) и очень узкий луч.
-
---
-
-### Итоговая архитектура (предложение):
-
-*   **Контроллер:** Arduino (Uno или Mega, если планируешь расширять количество датчиков).
-*   **Привод ленты:** Шаговый двигатель NEMA 17 $\rightarrow$ Драйвер A4988/TMC2208 $\rightarrow$ Arduino.
-*   **Сортировка:** 3 $\times$ Сервоприводы SG90 или MG90S (с металлическим редуктором надежнее).
-*   **Датчик высоты:** VL53L0X (I2C интерфейс).
-*   **Питание:** Отдельный блок питания 12В для двигателя и 5В для Arduino/сервоприводов (общий минус/земля).
-
-**Важное замечание из спецификации:** 
-Не забудь предусмотреть в логике категорию «Не подходит для сортировки» [1]. Если датчик зафиксирует объект, который либо слишком высокий, либо слишком низкий (выходит за допустимые габариты), система должна отправить его в отдельный поток или оставить на ленте до конца [1].
-
-Поскольку мы проектируем макет, важно учитывать не только функциональность, но и ограничения, упомянутые в техническом контексте: доступную площадь участка [1], разнообразие форм товаров (включая круглые в сечении) и необходимость бережного обращения с хрупкими или ценными объектами [1].
-
-
-# Сервоприводы с барьером — это надежный вариант, но в зависимости от того, какие объекты вы будете сортировать, рассмотрите следующие альтернативы:
-
-### 1. Электромагнитные толкатели (Solenoids)
-Вместо плавного поворота барьера, соленоид дает резкий линейный толчок.
-*   **Плюсы:** Очень высокая скорость срабатывания, компактность [1].
-*   **Минусы:** Резкий удар. Если ваши объекты хрупкие, этот вариант **не рекомендуется**, так как он противоречит требованию к «мягкости обращения» [1].
-*   **Когда использовать:** Для прочных, тяжелых или однотипных деталей.
-
-### 2. Откидная платформа (Tipping Platform)
-Это участок конвейера, который может наклоняться в сторону или под ним открывается люк.
-*   **Плюсы:** Позволяет перемещать объекты за счет гравитации. Это один из самых бережных способов перемещения, что важно для ценных или хрупких товаров [1].
-*   **Минусы:** Требует более сложной механической интеграции в саму ленту.
-*   **Когда использовать:** Если приоритетом является сохранность объекта и минимизация механических ударов.
-
-### 3. Поворотный диск-распределитель (Rotating Disc)
-В конце основной ленты устанавливается диск, который поворачивается на определенный угол, направляя объект в один из трех лотков.
-*   **Плюсы:** Занимает минимум места (оптимально для ограниченной площади участка [1]). Отлично работает с объектами, имеющими круг в сечении [1].
-*   **Минусы:** Требует точной синхронизации остановки ленты и поворота диска.
-*   **Когда использовать:** Если макет должен быть максимально компактным, а объекты имеют схожую форму (например, цилиндры или сферы).
-
-### 4. Боковой конвейер (Cross-Belt / Diverter)
-Это короткий перпендикулярный отрезок ленты, который включается только тогда, когда объект должен быть сброшен в зону.
-*   **Плюсы:** Самый профессиональный и «мягкий» метод. Идеален для хрупких товаров [1].
-*   **Минусы:** Высокая стоимость и сложность (нужно еще 3 маленьких мотора и дополнительные ленты).
-*   **Когда использовать:** Если вы хотите создать максимально приближенный к реальному промышленному производству макет.
-
-### Сводная таблица для выбора:
-
-| Вариант | Бережность (для хрупких [1]) | Компактность (площадь [1]) | Сложность реализации | Работа с круглыми объектами [1] |
-| :--- | :--- | :--- | :--- | :--- |
-| **Серво-барьер** | Средняя | Высокая | Низкая | Хорошо |
-| **Соленоид** | Низкая | Очень высокая | Низкая | Средне |
-| **Платформа** | Высокая | Средняя | Средняя | Хорошо |
-| **Диск** | Средняя | Очень высокая | Средняя | Идеально |
-| **Боковой конвейер**| Очень высокая | Низкая | Высокая | Хорошо |
-
-**Моя рекомендация:**
-Если вы хотите сохранить простоту управления через Arduino, но при этом учесть требования к бережности и компактности [1], я рекомендую остаться на **сервоприводах**, но изменить конструкцию барьера: вместо «толкателя» сделать **«поворотный желоб»** или **«шлюз»**. Это позволит объекту плавно скатываться в нужную зону, не подвергаясь резким ударам.
