In this talk I will present how I modified the remote control of a cheap 15$ quadcop in order to add a computer interface:
* First, I developed a small hardware board for signal tapping from and signal injection into the quadcop's remote control.
* Next, I connected an Arduino board and developed a small software written in the C programming language, that does real-time signal A/D conversion of incoming / outgoing flight control signals, time-stamping and low-level signal processing of incoming signal data, and buffering of incoming and outgoing signal data.
* Third, I connected a Raspberry Pi 3 board to the Arduino board and developed a Java Application that retrieves flight control signal data from the Arduino with the possibility to record it to a file. Also, the application allows for replaying recorded data back to the Arduino for signal injection into the quadcop's remote control.
* The next step would be to extend the Java application for either editing recorded flight control data or creating completely new flight control data from scratch.
