+Modèles principaux :
+
+| Modèle | Rôle |
+|---|---|

+
+## Overview
+
+**PlanarianScanner** is a web application developed for monitoring the activity
+and movements of **planarians** (*Platyhelminthes*) in laboratory research.
+
+The system controls a motorized multi-well scanner composed of a CNC arm (GRBL)
+and a high-definition ArduCam camera mounted on a Raspberry Pi 4. It enables
+automated image acquisition on a **6×4 wells × 4 plates** grid,
+high-performance storage of captures, and export to remote analysis machines.
+
+---
+
+## Hardware
+
+| Component | Details |
+|---|---|
+| Board | Raspberry Pi 4 |
+| Camera | High-definition ArduCam |
+| Motion system | CNC arm (L2544) controlled by GRBL |
+| Well grid | 6×4 × 4 multi-well plates |
+| Network | Local LAN — Samba/rsync export |
+
+---
+
+## Technical Stack
+
+| Layer | Technology |
+|---|---|
+| Backend | Django + Django Channels |
+| Real-time | Redis (broker + channel layer) |
+| Acquisition | OpenCV + Picamera2 |
+| Storage | ReductStore (high-performance time series) |
+| Asynchronous tasks | Celery + django-celery-beat |
+| Export | Samba (CIFS), rsync/SSH |
+| Platform | Raspberry Pi 4 — Debian Linux |
+
+---
+
+## Features
+
+### Application 1: Test Tube Scanner

+- CNC arm control through GRBL — automatic well-by-well movement
+- Multi-well calibration with database synchronization
+- High-definition image acquisition via ArduCam (OpenCV + Picamera2)
+- Frame storage in ReductStore time-series database
+- Configurable scan sessions (full grid or selected wells)
+- Asynchronous export (Celery):
+  - ZIP archive of JPEG images per session
+  - MP4 video generated from captured frames
+- Automatic transfer of exports to remote machines (Linux / Windows)
+- Nightly export scheduling via django-celery-beat

+- Supports multiple planarians with configurable parameters via Django or CSV.
+
+    - Strategy:
+

+          via the Hungarian algorithm (scipy.optimize.linear_sum_assignment)
+        - Independent inter-frame state per individual (PlanarianState)
+        - Returns a list of results, one for each tracked individual
+
+- Per-planarian CSV export compatible with EthoVision XT.

+Installation
+
+Full documentation coming soon.
+
+Using piImager, install Raspberry Pi OS 64-bit Trixie on the Raspberry Pi 4.<br>
+Customize your Raspberry Pi with at least SSH enabled (SSH key or password).<br>
+Later, for convenience, you may install a VNC server.
+
+ssh rpi4@ip.of.raspi
