Didnt understand. What it does? What is it for? What is it about? How to use? Usable for Android Phones???
Quite simple. mad scientists like me like that cool stuff.
Just have a look at dotscene.com an extended high scale developed flying mapping drone.
On a very low level you can use
Tello in combination with OpenCV, python, etc .... to do very simple scans.
Just to have fun with kids in a computer club to teach them that sience, mainly Physic, Math and Computer Science is not a Rocket Sience. Look the strange discussion around Computer Sicience at German schools today.
I hope to start again a computer club at a school at my home town. So I start now looking for sponsors
to buy a couple of
Tello's and Raspberry's.
