Like this guy's project


I made a similar project. IMG_0252.jpg IMG_0253.jpg
Here is the video:

The target was to make it fly in a circle, but it's a little bit troublesome, so I just made it fly to some points in a circle.

Now I simply use opencv(aruco library) to estimate the position of tello, and use pd controller to adjust it's position.

I used tellopy in my project.

It's open source, you can try it in my GitHub.

But to control the drone better, I want to know the attitude of tello(if you know how to get it, please tell me!!!! thanks!!)
also I will answer any thing I've made in my project.

I don't know the SDK but I think you will need to use the binary protocol to get that. All info is hidden throughout this thread, and in Krag's TelloLib also referenced therein


But I doubt that attitude will help you much for indoor control. Attitude data is not realtime but batched and delayed by at least 100 ms.
