So is Aradia to somehow... possess the robot, or just use it by remote control?
A kernelsprite that's been prototyped with a ghost should be able to possess people and objects, as one of its acquired powers. It's one of the things ghosts do.
EDIT: extra discomfort: Equius "paid a great deal of attention to quality and detail" on this facsimile of a female for whom he has amorous intentions.
One assumes she would be... fully functional.
