While I am still waiting for the pieces for my alarm clock to arrive, I’m continuing to develop my long-term project that I am going to present on this article.
Last summer I decided to build myself a drone : a quadcopter to be precise. My main goal is to create my own flight controller with an arduino card. Here is what it looks like now :
I didn’t want to spent much time choosing the motors or propellers so I bought a kit on Hobbyking with the frame, the motors and ESC (motor controllers) so I knew that there would be no dimension problem.
As long as electronics components are concerned, I chose to have a cheap alternate of the Arduino Uno (I know shame on me), and the MPU9150 as “attitude sensor”. I already had a Remote Controller (RX/TX).
The MPU9150 is 9 degrees of liberty sensor that is in fact composed of 3 sensors :
- a 3-axis accelerometer
- a 3-axis gyroscope
- a 3-axis magnetometer, which is the equivalent of a compass
My goal with this project is to program and understand the process of flight stabilisation. The first step will be to change the data from IMU into a pitch, roll and yaw indication.
