Any difficulties when developing software for drones?

Hi, guys!

I’m Mina, working at a startup company that develops software and algorithms for drones.
I’d like to hear more from you guys in terms of surrounding environments or current situations.

More specifically, have you had any difficulties when working on your algorithms or software? any developing issues popping on? If you are funded from school, how much does your school approximately give out? Or, if you are doing it on your own, how much do you think you can put on your project? When you used drones to work something out, were there any restrictions or problems popping up?
Just anything you are having difficulties with would be very helpful for us.

I appreciate any kind of participations!
Thank you :slight_smile:
