Area of Science:

  • Agricultural Engineering
  • Robotics
  • Computer Vision

Background:

  • Free-range chicken farming enables natural hen behavior but involves labor-intensive manual egg collection.
  • High labor costs associated with traditional egg gathering methods present a challenge for poultry farmers.

Purpose of the Study:

  • To develop a smart mobile robot for automated egg collection in free-range poultry farming.
  • To enable the robot to recognize, pick up, sort, and store eggs of different colors without damage.

Main Methods:

  • Utilized an egg feature extraction method with automatic thresholding for white and brown egg detection.
  • Implemented a behavior-based navigation system with visual tracking for obstacle avoidance and egg localization.
  • Designed a collection system for gathering, sorting, and storing eggs within the robot.

Main Results:

  • The robot demonstrated successful recognition, collection, and sorting of eggs in outdoor field experiments.
  • Average egg recognition rates ranged from 94.7% to 97.6% under varying climatic conditions.
  • The system proved effective in navigating and collecting eggs while avoiding obstacles.

Conclusions:

  • The proposed mobile robot offers a low-cost, simple-to-operate solution for automatic egg gathering on free-range farms.
  • This technology can significantly reduce labor costs and improve operational efficiency in poultry farming.
  • The robot's ability to handle different egg colors and operate in diverse conditions highlights its practical applicability.
