If you wanted to avoid a motor or servo on the rotating arm (and thereby the electrical hassle of extra wire or sliprings), you could run a setup similar to a helicopter's flybar. The flybar allows the rotor on a chopper to maintain a commanded orientation, regardless of where in the rotation the rotor is. It also translates changes up to the rotors. Something like that provides a mechanical solution to the problem (expense of weight). A slipring is probably the best option.

Ah I see! So basically since We HAVE to mount the servos directly on, it would be easier to do a slipring? And we're actually mounting the encoder to the outside of the shaft so that wiring is independent then taking the shaft and in the middle of the arm we're creating a "keyed" (really just filed) section the then move with the arm. No extra anything needed it just let's the encoder sit on the outside. So then we only have 3 servos on the claw. Sorry about the grammar, but I am on my iPhone getting posts in before sleep lol
