The flight of butterflies, characterized by its grace, agility, and efficiency, presents a captivating model for biomimicry. This project endeavors to emulate the complex flight patterns and structural elements of butterflies, leveraging advanced engineering techniques and bio-inspired principles. Our group combine with our own ideas to design and try to manufacture a bionic butterfly which can achieve the function of stably flying and rotating. The total cost is about 1000 yuan, and it is has finally been tested in physical manufacturing and basic functions.

The project aims to create a biomimetic butterfly model inspired by the intricate and efficient flight mechanisms observed in nature. The expected outcome of the project is to make a biomimetic butterfly prototype capable of emulating the flight motions observed in natural butterflies, including flying forward and rotating stably.

During the project, we have completed the following work:

a)       Calculation and simulation: We have calculated and simulated the aerodynamics and kinematics of the bionic butterfly, based on the ANSYS Fluent.

b)      CAD design: We have designed the 3D model of the bionic butterfly, including the body, the connection parts and the wings, using Solidworks.

c)       Controlling code writing: We have successfully designed and coded a controlling system based on Arduino Nano board, using Futong i6 remote controller and A8S receiver to control the initial angle, amplitude limit and rotation speed of two servos in real time.

d)      Parts processing: We have purchased the necessary materials and components for the bionic butterfly and processed the parts of the bionic butterfly.

e)       Prototype test and improvement: We have assembled the parts of the bionic butterfly and tested its functionality and performance and made some improvements based on the results.
