Hi all, I am trying to get an ardrone to fly by getting directions from tags. I am having problems correcting my roll, pitch and yaw, To be honest my code is based off of someone else, and I am not sure I understand it properly, but basically when I detect a tag (using artrackalvar) I then run the command:

 roll, pitch, yaw = euler_from_quaternion([data.pose.orientation.x, data.pose.orientation.y,    data.pose.orientation.z, data.pose.orientation.w])

I was hoping this would give me the roll, pitch and yaw with respect to the tag but the results I am getting don't make any sense. My roll and yaw are always either ~3.14 or ~-3,14 (roll and yaw aren't identical, one might be positive and the other negative, but they both get those values) My pitch is mostly between 0.2 and -0.2.

I could not figure out any correlation between my drones orientation and the roll, pitch and yaw I am getting, so I am assuming I am doing something completely wrong, but if Im somehow making sense then any help as to how to correct myself would be greatly appreciated.

If there is a better way to go about it I am open to suggestions.

Thanks for any help available!
