Towards Autonomous Aircraft Towing Car: Path Planning Based on Enhanced RRT Algorithm
摘要
The Aircraft Towing Car is essential in airport ground operations, with automation playing a crucial role in enhancing efficiency and safety. This study introduces an Enhanced Rapidly exploring Random Tree (RRT) algorithm to improve the operational capabilities of Autonomous Aircraft Towing Cars. A high-fidelity virtual testing environment was developed using the ROS/Gazebo platform to address practical operational conditions and spatial constraints. An integrated system automates tasks before and after towing engagement, focusing on dynamic path planning after coupling. The Enhanced RRT algorithm incorporates real-time path planning, target biasing, and dynamic map adjustments to navigate restricted zones while ensuring compliance with aviation safety standards. Validation was performed using a 2D maze map and a 2D cost map with restricted zones, comparing the proposed algorithm to traditional methods. Results demonstrate that the enhanced RRT achieves faster convergence, fewer iterations, and lower path costs, excelling in complex environments.
