🧠 Overview

Summary of the project, design philosophy, and objectives.

🧰 Setup Guide

Setup the environment using Hailo’s official RPi repo:

git clone https://github.com/hailo-ai/hailo-rpi5-examples.git
cd hailo-rpi5-examples
./install.sh
source setup_env.sh

Then run the system:

python detection/detection.py \
  --labels-json resources/nut_bolt-labels.json \
  --hef-path model/nut_bolt_model.hef \
  --input rpi

🧱 Mechanical Components & CAD

This project includes custom-designed mechanical components modeled in Creo Parametric and fabricated using 3D printing. Key components include:

• 🔧 Flapper mechanism for nut/bolt sorting
• 📦 Servo mounting bracket
• 📷 RPi HQ camera holder
