Hello everyone, I’m Victor and you probably haven’t heard of me yet but I’ve got the awesome opportunity to spend some weeks during this summer working at Bitcraze. Working… Well, I’ve spent the majority of my time here getting invaluable experience, programming, flying with drones, eating incredible falafel and having fun so it’s really been a pleasure.

I’m quite new to both programming and electronics, so while I haven’t created any huge masterpieces of code yet, I did make a small program with a GUI that let you test the health of motors and propellers of the Crazyflie. You can run multiple ones simultaneously (I’ve tried up to 8, which works fine, even with a single radio, and you should be able to run many more) and it relies on using either Lighthouse or a Flow deck for positioning.
The propeller-test is essentially the same test as the one integrated with the cfclient, however the motor-test checks the thrust-levels of the motors (by hovering in the air for x seconds) to see if any of them are off and ranks them as good/bad. The default threshold is 15% but can be changed according to needs. The program is written in Python and uses tkinter to run the GUI application and the cflib to communicate with the Crazyflie. The script can be found here.

In the end of August I’m going to study Computer Science and Engineering which I’m extremely thrilled about and this has really been a perfect preparation for that! In the future I hope to contribute to the Crazyflie projects and learn more from the great team here at Bitcraze.

So until next time, fly safe!
Victor
