1. Overview
A mechanical sweeper designed to automatically collect, evaluate, and arrange badminton shuttlecocks using a wheel-driven conveyor system and optical sensors.
2. Problem
Manually collecting and sorting damaged shuttlecocks after badminton practice is inefficient, time-consuming, and physically demanding.
3. Mechanical Design
Engineered a wheel-powered conveyor belt system with brush-type propellers to sweep and lift shuttlecocks without requiring an external power source for mobility.

4. Smart Classification
Developed an Arduino-controlled sorting module utilizing 16 IR light sensors to evaluate the structural integrity of shuttlecock feathers, automatically separating damaged units from reusable ones.

5. Tech Stack & Fabrication
- SolidWorks (CAD & Mechanism Design)
- Arduino / C++ (Sensor integration & Motor control)
- 3D Printing & Aluminum Profile Assembly
