I am writing a term paper (for my university) within the framework of which I've developed a new position controller for the Crazyflie. For my final report I need to use several pictures of the Crazyflie. So, instead of making low quality pictures by myself, I would like to use the picture of the Crazyflie from the website:
https://www.bitcraze.io/products/crazyflie-2-1/
One picture will be used as it is, and the second one will be modified with some coordinate frames...
Of course I will cite this pictures and will give the reference, but officially to do that I also need your permission.

Best regards!
