The search for planets around stars with empirical methods turn out to be as one of the most remarkable astronomical topics since late 90's. New observational techniques and instrumentations which are introduced in last decade made possible the discoveries of very low-mass and planetary companions around distant stars. More than 340 exoplanets have been discovered so far (see http://exoplanet.eu) and their numbers are still increasing. Most of them are discovered with Precise Radial Velocity Measurement Technique. In this contribution, we shall give a summary on our exoplanet search project started at TUBITAK - Turkish National Observatory in the framework of an international collaboration between Turkish, Japanese and Russian colleagues and present the achieved radial velocity precision after the 2 years of test observations.
