The Garden Guardian is an advanced robotic system designed to protect gardens from monkey intrusions using a humane deterrence mechanism. This project, developed by Muhammad Ammar Yaseer Bin Azizan, leverages cutting-edge technology to ensure effective and non-harmful deterrence.

Key Features:

• Robotic System: Powered by Raspberry Pi 5 and Arduino Uno R4, the system is equipped with a 30W speaker and TDA7266 amplifier to emit sounds that deter monkeys.

• Movement Tracking: Utilizes MG996 180-degree servo motors, controlled by the PCA9685 PWM module, to track monkey movements both vertically and horizontally.

• Real-Time Monitoring: A web interface developed with the Flask framework facilitates real-time monitoring. Secure access is ensured through user registration and login, with notifications sent via email and WhatsApp when a monkey is detected for more than three seconds.

• Hardware Components:

  • DFRobot DFPlayer Mini: Produces deterrent sounds.
  • Joystick Module with ADS1115: Allows manual head positioning.
  • LCD1602 I2C: Displays button functions for user interaction.
  • Webcam: Provides high-quality tracking and recognition of monkeys.

• Design and Fabrication: The robot’s base and head are designed using SolidWorks and fabricated through metal bending, with 3D-printed covers made from PLA material.

• User Interface: Features three buttons for controlling the robot’s functions—power on, manual mode, and AI mode—with an additional button for toggling motion detection.

Future Enhancements:

• Optimization: Plans to optimize YOLOv5 models for edge devices like Raspberry Pi.

• Patrol Capabilities: Exploring the integration of ROS for broader coverage.

• Enhanced Deterrence: Considering the addition of a water gun for improved deterrence.
