The four-axis aircraft is also known as the four-rotoring aircraft, a four-rotor helicopter, referred to as a four-axis, four rotor. This four-axis aircraft (quadrotor) is a multi-rotator. The four propelles of the four-axis aircraft are simple mechanisms directly connected to the cross-shaped layout allows the aircraft to adjust their own posture by changing the power of the rotating body by changing the motor speed. Specific technical details are described in the Basic Motion Principle. [1] Because of its inherent complexity, there is no large commercial four-axis aircraft in history. [1] In recent years, it has benefited from the development of micro-electromechanical control technology, and the stable four-axis aircraft has been widely concerned, and the application prospect is very considerable.

3, four-axis aircraft full information (four-axis schematic + PCB + remote control schematic + four-axis and remote control source code + top papers)
This project is my graduation design (big first learning single chip, big two contact STM32 must have a whole tall, there is this kind of actual at the time, flying directly on the head of the judges at the time of the judgment 98 Divided .. Haha), for a year, including program design, component procurement, painting PCB, procedure, write procedure, debug (including flying control and remote control). Now you can fly, add a small camera, you can fpv, and you can drop it. It is best to take the best to use the four-axis aircraft, and you can study the four axes.

7. Design of simple four-axis aircraft based on single chip microcomputer
The four-axis aircraft has all the advantages of Vtol (verticaltake-offandilanding, vertical and landing) aircraft, and has the characteristics of low cost, high repeatability and low accident cost, and has broad application prospects. Can be applied to military ground battlefield reconnaissance and monitoring, and get information that is not easy to obtain. It is possible to perform special tasks such as patrols and close air support, which can deal with modern warfare models such as modern electronic warfare. In civilian aspects can be used for many aspects such as post-disaster search and rescue, urban traffic patrols and target tracking. Industrial can be used in safe inspection, large chemical site, high-pressure transmission line, dam, bridge, and seismic mountainous areas.
This design mainly includes two parts: the remote control and the aircraft, the central processor CPU uses STC15W4K58S4, IAP15W4K58S4 (both can simulate the USB direct download program), is one of the most advanced chips of STC, and the internal resources are very rich. 58K byte memory, 4096 byte data memory, 5 timers, 4 independent serial port, 8 channels 10 high speed ADC converters, 1 SPI interface supports host and slave mode, 2 channels CCP / PCA / PWM, 6-way belt-dead zone control dedicated PWM, 1 comparator, etc., support USB direct download programs and serial download programs, internal integration, high-precision R / C clock and high reliability reset circuit, support 2.5 ~ 5.5V wide operating voltage range . The wireless communication between the aircraft and the remote control uses the NRF24L01 module of the 2.4GHz communication frequency band. The NRF24L01 module and the MCU communicate between 1 MHz communication rate between the NRF24L01 module and the MCU; the aircraft end is mounted with a 3-axis accelerometer integral with a three-axis gyroscope The MPU6050 inertial measuring unit is used as a posture Euler angle measuring unit, and the MPU 6050 communicates with the I2C protocol between the MPU 6050 by the I2C protocol; the aircraft terminal MCU is calculated by receiving wireless data and collecting the MPU6050 data through the four-dimensional complementary filtering. The angle, the motor PID automatically controls, and finally drives the hollow cup 820 DC brush motor with a 20kHz PWM to achieve the design of the remote four-axis aircraft.
