Final CAD Model

🛠️ Hardware + Firmware

• Custom CAD-designed turret with 2 DOF (pitch + base rotation)
• AprilTag detection to locate each plant and calculate distance + offset
• PID alignment with trigonometric computations for optimal water trajectory
• Servo-controlled tunable water gun for precision watering
• Powered by Arduino and controlled via Python serial interface

☁️ Cloud + Web App

• Firebase backend + Next.js frontend deployed on Vercel
• Robot publishes:
  • Soil moisture sensor data
  • Computer vision snapshots for analysis
• Web app enables remote control:
  • Water now
  • Run plant scan
  • Get current moisture status
• Commands execute in real time via a Python threaded controller
• Full remote monitoring — no local setup required

🧩 Python Control Layer

A multithreaded Python system integrates all components:

• Runs computer vision (AprilTag detection)
• Manages serial communication with the Arduino
• Handles Firebase reads/writes
• Oversees timing, alignment, and command execution
• Enables smooth, concurrent hardware + cloud operations
