Area of Science:

Robotics and Automation
Agricultural Technology
Computer Vision

Background:

Traditional SLAM (Simultaneous Localization and Mapping) faces challenges in complex environments like multi-layered chicken coops.
Issues include low effective particle counts, high particle repetition, and point cloud penetration, hindering accurate robot navigation.

Purpose of the Study:

To develop an optimized mapping method for chicken coop disinfection robots.
To improve the accuracy and robustness of Simultaneous Localization and Mapping (SLAM) in livestock environments.

Main Methods:

An improved Iterative Closest Point (ICP) algorithm was employed to enhance laser point cloud registration.
Particle sampling was optimized by limiting range and screening based on predicted particle poses and map matching.
Environmental map information particle diversity and accuracy were enhanced.

Main Results:

The proposed mapping method achieved a maximum error of 3.5 cm in chicken coop environments.
Significant improvements in laser point cloud registration performance were observed.
The method effectively preserved the unique environmental characteristics of chicken coops.

Conclusions:

The developed mapping method is effective and robust for chicken coop environments.
This research provides a scientific foundation for navigation systems in livestock and poultry breeding robots.
Optimized SLAM techniques are crucial for advancing agricultural automation.
