Design of Quadrotor UAV Based on MSP432

Abstract

In order to solve the problems of UAV flexibility, stability and safety, this paper designs a quadrotor UAV based on MSP432. The UAV includes five parts: main control part, flight height measurement module, gyroscope, fixed point correction module and visual recognition module. In order to protect the main control and other parts, we designed the outer protective carbon plate, so that its security is greatly improved. Based on the in-depth study of the existing remote control flight function, an improved active disturbance rejection controller is added, and the dual control mode of autonomous control and manual control is adopted to prevent unnecessary losses due to operation errors. The combination of GPS and laser rangefinder allows for more precise fixed-point positioning and measurement of the altitude above the ground, allowing the operator to determine the position of the UAV so as to observe its status. The integration function and key technology of each subsystem of UAV are analyzed in detail by simulation software. The experimental results show that each part of the quadrotor UAV and the surrounding protective carbon plate can provide a systematic solution for the intelligent and systematic development of the UAV, further improve the stability, flexibility, safety and the ability of swarm intelligence of the UAV, and make it have a better performance in the flight process.
