KAIST Mobile Software Project - Drone Heliport Platform

본 토픽은 현재 준비중입니다. 공동공부에 참여하시면 완성 되었을 때 알려드립니다.

1. Selection of Drone model and purchasing the components

* The consideration for selecting model of Drone Flight Controller

1. Whether it supports Open source for Flight Controller(FC)

     => FC should supports open source for controlling drone. The source code can be modified and re-build without any problem.(This is the most important.)

2. Whether it supports the interface for external communication like a UART.

     => It should support connection and communication between FC and raspberrypi board.(Important)

3. Price - School supports only small money.

     => The price of all drone components is ten million twenty thousand won. 

          Remote controller supporting 2.4Ghz 9ch is three million ninety thouand won.

 

 

4. Controlling Drone should be easy.

    => Basically Drone should be easliy controllable to do hovering in the fixed position.

         Without this skill, we could not continue this project. 

         For improving control skill, we purchased controller simulator and have practiced much.

 

In the Drone market, there are three major manufacturers. Parrot(EU), DJI(Chania), 3D Robotics(USA).

All of them supports open source but take a little different direction to the Drone market.

Parrot supportㄴ easy control of Drone. People plays with it as a just Toy. 

DJI products has low price because of producing by china. It looks for advanced and supports open source but there are only few documents and not many users who are using that. Therefore there are no references. 

Finally, we selected PixHawk of 3D Robotics.  It supports Open source very weel and there are rich documents and guidelines.
