# Research Progress and Prospects of Agricultural Aero-Bionic Technology in China
###### Abstract  
Accelerating the development of agricultural aviation technology is the need of China's modern agricultural construction. With the rise of emerging industries such as artificial intelligence, biotechnology, autonomous navigation, and the Internet of Things, agricultural aviation is further developing toward the direction of intelligence to meet the requirements of efficient and sophisticated agricultural aviation operations. Bionics is a multi-discipline and comprehensive border subject. It is produced by the mutual penetration and integration of life science and engineering science. Bionic technology has received more and more attention in recent years, and breakthroughs have been made in the fields of biomedicine and health, military, brain science and brain-like navigation, and advanced manufacturing. This study summarized the research progress of biomimetic technology in the field of agricultural aviation from three aspects of biological perception, biological behavior, and biological intelligence. On this basis, problems of related research and application of agricultural aircraft in real-time obstacle avoidance, path planning, and intelligent navigation were analyzed. Combined with the practice of the rapid development of agricultural aircraft, research and application of bionic technology suitable for agricultural aircraft were then proposed. Finally, prospects of agricultural aero-bionic technology were also discussed from multiple bionic target fusion, three-dimensional spatial information exploration, sensors, and animal brain system mechanism. This review provides a reference for the development of bionic technology in China's agricultural aviation. agricultural aviation; aero-bionic technology; unmanned aerial vehicle; obstacle avoidance; path planning; convolutional neural network; sensors; review +

aviation is moving towards intelligence [4; 5]. As one of the new technologies that are of great significance to the development of emerging industries in the future [6], bionic technology provides new ideas for the intelligent development of agricultural aviation. Bionic sensing technology can realize the precise operation and real-time obstacle avoidance of agricultural aircraft, which is one of the important directions for the development of intelligent agricultural aviation in the future [7]. Bionic intelligent technology can complete autonomous learning and intelligent decision-making, realize autonomous navigation of agricultural aircraft, and improve operational efficiency [8]. The intelligent bionic algorithm can improve the operational path optimization and multi-aircraft cooperative operation of agricultural aircraft, which is the development trend of mobile robot path planning in the future [9]. Bionics, founded in 1960, is a science that studies biological systems, structures, traits, and working mechanisms. At present, bionic technology has penetrated into almost every field, and scholars from all over the world have carried out related research on bionics and made breakthrough progress. A lightweight and high-strength aircraft [10] was developed by imitating the truss structure of insect wings [11] and the dumbbell-shaped structure of animal bones [12]. Inspired by the sensitivity of cellulose to humidity, the spider egg sac silk was used to develop a humidity sensor with high sensitivity, heat resistance, and repeatability [13]. Through the research of the elephant nose and octopus hand, a flexible robotic arm has been developed, which has the characteristics of strong flexibility and adaptability to complex environments. The combination of bionic technology and agricultural aviation can achieve precise control of aviation aircraft, enabling it to have functions such as intelligent navigation and fine pesticide application, which is of positive significance to the development of precision agricultural aviation.
