The Fibre Multi-Object Spectrograph (FMOS) for the primary focus of Subaru Telescope is one of the second generation instruments, aiming at acquiring spectra of faint objects with target multiplicity of up to 400. The optimised wavelengths span from 0.9 to 1.8 microns so as to extend our knowledge of galaxy formations and evolutions at higher redshifts in a systematic way, as well as of variety of intriguing near-infrared objects. On the basis of detailed design of FMOS, actual processes of fabrication are in progress, and some of critical hardware components have successfully been developed. In this report, we present the status of the FMOS project, the results of developed components, and also instrument control systems such as the new detector electronics as well the related contol softwares.
