🤖 SENTRI — Automated Pickup & Cleaning Robot

Summary:
SENTRI is an autonomous robot designed to navigate cafeteria tables and collect leftover bottles. The system integrates perception (YOLOv8n-based object detection), navigation control, and a simple pickup mechanism to perform table-level cleaning tasks.

My Role: System designer & Computer Vision developer

Technologies Used: Raspberry Pi, Arduino Uno, Python (OpenCV, YOLOv8n), Arduino C, DC motors, motor drivers

GitHub Repo: View Project

Key Achievements / Outcome

• Built and tuned a vision pipeline that works under mixed indoor lighting.
• Implemented robust pickup behavior with sensor feedback.
• Demonstrated the integrated prototype in live cafeteria trials.
