Autonomous Robot for Basketball Rim Detection & Shooting

• Led all software and AI development in collaboration with Mechanical Engineering students who built the robot hardware.
• Developed a custom-trained YOLOv11 model for real-time basketball rim detection and autonomous shooting.
• Annotated 400 images to prepare the training dataset for the object detection model.
• Programmed Arduino to control movement, positioning, and shooting mechanism via USB serial communication.
• Integrated a USB camera for rim detection and distance estimation, with Python logic triggering shooting when within optimal range and detected objects.

Autonomous Robot Navigation with YOLO11 Object Detection

• Built a manual motor control interface in Isaac Sim and established a ROS2 bridge for seamless communication between the simulation and ROS ecosystem.
• Implemented the YOLOv11 AI model to perform real-time object recognition using a simulated camera within the Isaac Sim environment.
• Streamed camera and LiDAR sensor data to RViz for real-time visualization and environmental perception.
• Developed Python-based control logic that enables the robot to autonomously navigate, locate, and approach target objects.
• Integrated a perception pipeline combining computer vision (YOLO) with spatial awareness (LiDAR) to support intelligent decision-making.

2048 Puzzle Game - Dual Language Implementation

• Implemented core 2048 game logic including tile merging, four-direction movement, random tile spawn, and win/loss detection.
• Built scoring system that accumulates points when tiles merge (value × 2) and a real-time timer tracking game duration.
• Developed a persistent ranking system storing top 10 scores with custom player names, sorted by descending scores.
• Added interactive multimedia effects for moves, tile merges, wins, and game over events.
• Created console-based GUI with color-coded tiles for improved visual clarity and accessibility.
