n the last 40 years, astronomers have charted the 3D position of galaxies in the Universe. With the recent Sloan Digital Sky Survey (SDSS) and the Dark Energy Spectrosopic Instrument (DESI) survey, a much clearer picture is arising on the matter distribution across the Universe. These measurements confirm the Lambda-CDM cosmology model even though some tension in the model still exists, and need to be understood. I will give a summary of the recent progress and understanding, as well as an outlook of the future projects. In particular, I will present the required instrumental development needed in robotics to make the next generation spectroscopic survey possible.
