Abstract: This paper expounds the development process of the mini quadrotor aircraft teaching platform. Firstly, the shape is designed and processed by using 3D printing technology, and the modular assembly is realized. And then the open source flight control resources are used to guide students to design the schematic circuit and PCB. Finally APP software is developed for control. Because this teaching platform is small in size, high in safety, and has the same functional principle as other large-wheelbase quadrotors, the design and production process of this platform can be used for teaching, so that more students can participate in it. This course can not only open up students’ innovative thinking, but also exercise students’ hands-on ability. The course has been practiced many times, and the effect is remarkable, which proves the practicability of this platform in practice teaching.
