Auto Docking Vessels

This project presents a Webots simulation environment and a vision-based autonomous docking algorithm for robotic vessels with a novel latching system that enables robotic boats to create dynamic united floating infrastructure while overcoming water disturbances.

This project is fonded by China National Innovation and Entrepreneurship Training Program.

Features

• Docking scene simulation in Webots
• Vision-based autonomous docking algorithm
• ArUco pose estimation
• Omni-directional locomotion controller
• GPS and IMU filtering with the moving window filter
