Abstract: This paper describes the design of an optical fiber actuator of the arm type for multiple-object spectroscopy, based on the arm systems described by Hill (1986) and Ingerson (1987). The equipment (called Medisis) has three arms activated by step motors under computer control. Each arm-tip is carrying two single-core fibers for spectrographic use, one for the object, one for the sky recording. On the same tip, there is a coherent image-conducting fiber bundle for locating objects with poorly known coordinates. An anticollision software is controlling the instrument and deciding the arm object fit.
