@Dragoranos Obviously, for movement beyond default angle values, you would need something more complex.
However, I'm not sure I can provide any useful information in that area, since I'm not familiar with how the vehicle you are designing works.

@Dragoranos For up/down rotation, you might try some sort of -PitchAngle input (X axis). You could also try some sort of -Heading input for left/right rotation (Y axis).
If the movement is positional instead of rotational, then I don't have a solution at the moment.
This may or may not work, since I don't specialize in these types of vehicles/mechanisms.
Also, if I misunderstood, and you need Z axis inputs, you might try some sort of -RollAngle input.

up down left right

@Dragoranos Hmm. Along what axis does the part you are referring to move? (X, Y, or Z axis.)

@TheFlightGuySP A gyro stabilizer is not what I'm looking for
I found it has some downsides that prove to be very annoying for certain types of builds

@Dragoranos Ah I see. In that case, I believe Walvis has a tank stabilizer tutorial video. I know your post says that it's not just a tank, but it may still apply to whatever vehicle you are making.
Other than that, I don't really have any suggestions.

@TheFlightGuySP No, something to keep a moving part level while the rest of the vehicle moves

Are you referring to artificial stability for an aircraft?
