All possible photos we can take (as far as I know) of Caretaker is from an tilted position looking to the drone when it change views with the photo robot.
After that the Caretaker stay in the tilted position all the time while we are using the drone.
Maybe, after the change of POV the caretaker at least go back to standing position. Or if possible the Caretaker could move after some commands? Idk, but so far we never been able to take "selfies" of the Caretaker doing things or showint the weapons, etc.
