The Navigation of Robotic Fiber Positioners in SDSS-V Project: Design and Implementation

SDSS-V project is one of the major observational cosmological projects which aims to generate the map of the observable universe by collecting spectroscopic data from the sky using optical fibers. Each optical fiber is attached to a robotic positioner to be automatically coordinated. This paper illustrates the solution to the navigation problem of robotic fiber positioners corresponding to the SDSS-V project. We note the principal challenging requirements to navigate the robotic fiber positioners. These requirements are those which differentiate the navigation problem of the SDSS-V project from that of the other projects. Then, we discuss the solution in view of both design and implementation. In particular, we specify the hardware and the software components of the solution in a systematic perspective. We illustrate the effectiveness of our solution based on practical results.
