AI Technical Summary
Existing technologies for visual navigation and positioning on wind turbine blade surfaces lack robustness, adaptability to unknown environments, safety of control strategies, and closed-loop feedback capabilities. This leads to problems such as pose estimation drift, path drift, accumulated deviation, collisions, and missteps that can easily occur during robot inspections.
A multi-legged robot motion control method is adopted, which acquires RGB images and depth images through a depth camera, extracts surface edge points by fusing edge detection, plans the foot trajectory using cubic Bézier curves, and performs closed-loop control by combining visual deviation closed-loop feedback and contact torque feedback to achieve stable inspection.
It improves the robot's motion adaptability and safety in complex curved surface environments, reduces collision risks, achieves stable path tracking and navigation functions, and enables autonomous mapping and path planning in unknown environments.
