The astrometry technique is an important tool for detecting and characterizing exoplanets of different types. In this review, the different projects which are either operating, in construction or in discussion, are presented and their performance is discussed in the framework of the Blue Dots study. We investigate the sensitivity of astrometry to different sources of noise and we show that astrometry is a key technique in the path of discovering and characterizing new types of planets including the very challenging category of Earth-like planets orbiting the habitable zone of solar-type stars.
