Research and design of four axis aircraft based on TM4C123G

With the development of UAVs, more and more technologies are applied to UAVs. New wing shapes and light materials have greatly increased the endurance of UAVs. The use of advanced signal processing and communication technologies has improved UAVs’ performance. Image transmission speed and digital transmission speed; the application of these technologies has improved the technical performance of UAVs and enlarged the application range of UAVs. With the continuous innovation in the technical field and the strong support of the country, I believe that the update and development of drone technology is becoming more and more perfect, and the future prospects of drones will be infinitely great. With UAV obstacle avoidance and tracking technology becoming the focus of the industry, it has important application value in cruising, tracking and other fields. This project aims to take the interest of drones as the carrier, with the TI Cup competition problem circumventing aircraft as the goal, to explore the UAV obstacle avoidance system. The quadrotor has reasonable structure, small size, light weight, and peripheral hardware circuit requirements. The advantages of low height, relatively simple control procedures, and vertical take-off and landing have made quadrotors more widely used. This project focuses on UAV obstacle avoidance, with STM32 chip as the main control, and elaborates on UAV information reading, calculation and control. This design is based on reality and uses STM32 series single-chip microcomputer as the control core. The real drone of this project realizes the acquisition of information through a number of sensors, and then the drone’s master STM32 chip reads its own sensor data, including the roll angle of the aircraft. , Pitch angle and yaw angle and other key information. After the UAV master control obtains the information, the cascade PID algorithm is used to calculate the speed of the four motors. Finally, the main controller sends the resolved information to the ESC through the interface to adjust the states of the four motors, thereby realizing the control of the flight attitude and ensuring the smooth operation of the aircraft.
