Abstract
With the advancement of modern technology and the continuous development of science, research into flapping wing aircraft is becoming increasingly sophisticated. Addressing issues such as the large wingspan and heavy mass of existing bionic butterfly aircraft, this paper proposes the design of a lightweight lithium battery power supply, a chip integrated into a small circuit board, and a reference to the natural characteristics of butterfly wings. The wings are simulated using 0.125 mm polyethylene terephthalate (PET) film to replicate their movement. The driving structure employs a double motor and a four-bar mechanism to achieve natural and smooth wing vibrations. The control system features a lightweight motor, battery, and a high-performance low-power microcontroller for precise control. Using 3D printing technology, a lightweight design is realized, successfully simulating the structure and movement characteristics of a specific butterfly, demonstrating the principles of mechatronics. Furthermore, the design process incorporates multidisciplinary knowledge, and a workshop combining competitive discipline events with innovation and entrepreneurship has been established. This initiative fosters the deep integration of innovation and entrepreneurship education with professional training, effectively cultivating application-oriented technical talents.
