FiberPolish Smart System

A touch-friendly Python HMI for controlling a fiber-optic polishing machine on Raspberry Pi 5 with a 7-inch touchscreen.

Project context: This repository is the GitHub snapshot of an internship project developed at Quantum Center. The deployed/prototyped system was developed around Raspberry Pi hardware owned by the center. The repository is preserved as a portfolio snapshot and is not intended to claim production-ready industrial safety certification.

Architecture

The application follows a lightweight Model–View–Presenter (MVP) structure:

• Model: hardware-facing control classes for the light, Lissa motor and polishing/column motors.
• View: the ttkbootstrap touchscreen GUI and its control panels.
• Presenter: connects GUI events to the corresponding model and keeps interaction logic out of the view.

Features in this repository

• Touch-friendly control panels
• Light brightness control
• Lissa motor ON/OFF control
• Polishing pad speed and direction control
• Column up/down control
• Stopwatch and countdown UI
• Drawer-style navigation
• Full-screen/kiosk-oriented UI
• Raspberry Pi GPIO integration through gpiozero

Some UI sections are intentionally kept as prototype/in-progress elements because the original hardware environment is no longer available to the author.

Installation

Requirements

• Python 3.10+
• Raspberry Pi 5 for real GPIO/hardware operation
• 7-inch touchscreen (recommended for the intended HMI layout)

Clone the repository:

git clone https://github.com/matin-mohamadi/FiberPolish-Smart-System.git
cd FiberPolish-Smart-System

Install dependencies:

python -m pip install -r requirements.txt

Running

The current source uses project-local imports, so run the entry point from the src directory:

cd src
python main.py

This application expects Raspberry Pi GPIO hardware for the hardware-facing models. Running it on a normal laptop without the required GPIO environment is not expected to reproduce the full system behavior.

Hardware mapping

The GPIO mapping currently defined in src/main.py is:

Function	GPIO
Light	18
Lissa motor	26
Pad PWM	12
Pad CW	13
Pad CCW	6
Column enable/PWM	19
Column direction	5

Safety: This software controls physical hardware. The repository should be treated as an internship/prototype codebase, not as certified industrial safety software. Hardware behavior must be independently verified before any real-machine deployment.

Status

The original internship work is complete. The repository is maintained as a portfolio snapshot rather than as an actively developed product.
