ROS 2 Nav2 agricultural-navigation paper validates real-time costmap updates on Husky

Evidence notes

• The paper extends the ROS 2 Navigation Stack with depth-camera classification and real-time local costmap corrections for outdoor agriculture settings.
• The system is implemented and validated on a Clearpath Husky to traverse tall grass and weeds that standard LiDAR costmaps may treat as obstacles.
• The work adds a Husky research example for practical outdoor Nav2 adaptation in orchards, vineyards and field-like environments.
