Abstract: Against the backdrop of global promotion of clean energy transformation, the wind power industry is rapidly expanding. As one of the important tools to ensure the reliable operation of wind turbines, low altitude flight inspection robots for wind power have attracted much attention for their technological development. This article introduces the key technological research progress in the fields of control technology and structural design. In addition, this article summarizes the limitations of existing technologies in terms of multi-sensor fusion accuracy and real-time path planning algorithms. In the future, with the development of artificial intelligence, new materials, interdisciplinary integration, and communication technology, the performance and reliability of wind power low altitude flight inspection robots are expected to be further improved, providing stronger support for efficient operation and maintenance of the wind power.
