This project is dedicated to the development of a DIY quadcopter and its remote controller. The hardware, firmware, and software have been developed from scratch.
The quadcopter and the controller are both equipped with 2.4GHz radio transceivers. The controller consists of two parts:
- An Android smartphone running an application that allows receiving and displaying telemetry data from the quadcopter, as well as adjusting quadcopter control system parameters such as PID controller coefficients
- A custom Arduino-based board to which the smartphone is connected via Bluetooth. This board essentially serves as a data converter, transmitting information received via Bluetooth over the 2.4GHz radio, and vice versa
MCU: STM32F103
IMU: GY80 (L3G4200d + ADXL345 + HMC5883 + BMP085)
Radio: NRF24L01
ESC: Chinese ESC with SimonK firmware
Motors: SunnySky X2212-13 980KV
Frame: Chinese noname one
Based on: Arduino Nano
Radio: NRF24L01
Bluetooth: HC-05
The firmware was developed from scratch in C, except for the IMU code, which was taken from here
The software in this project is a custom application written in Java for Android. Here are a couple of screenshots of this application:
