I'm new to topic of gimbals. I'm trying to accomplish following scenario: I have a phone, and I want to keep its camera always facing ceiling (parallelly) and always in same rotation in respect to xy coordinates.
To illustrate this: While I move (and rotate) with phone from point A -> B -> C, I want it to have always the very same xyz rotation.
Is it possible to achieve this with commercial phone gimbals? If yes, for which features in specifications should I look for to know gimbal is capable of it?
