Abstract-With the development of science and technology, the science and technology used in military investigation and surveying and mapping are becoming more and more advanced, and small reconnaissance UAV gradually walked into people's lives. This paper mainly aimed at the improved design of the existing reconnaissance robots. It has improved the aesthetics and practicability of the small detection machine from the aspects of material, appearance, form, working method and manmachine interaction. The small surveillance aircraft can be used both on land and in the air, thus satisfying multi-disciplinary and multi-form work requirements.
