My pots are ordinary under 1$, the neck and head motor both will have less than 180deg. movement.The state of neck and head (turning left or right, up or down) will be reported by pot for the process and by limiting micro switches for end points so this should not be a problem. I first added micro switches and implemented them, then I had a problem with debouncing and turned to forum and made a post some days ago. Got great new ideas like always. Now in redesigning (will use debouncing with flip-flop chip this time, as suggested by community people).
Well for less than a full circle you a rotary encoder can still offer better precision then the setup you describe, but the much greater cost of a precise rotary encoder means the potential improvement is probably not worthwhile.
