Hii Yukesh!
As robotics engineer the starting salary in India is three lakhs to four lakhs per year. But as the person gains more knowledge and experience eventually the salary can go on increasing with time. Robotics is indeed a promising career option in India and its scope is increasing day by day. You can even get easy placements in foreign countries through IITs. The beginner robotic engineer easily earns sixty thousand dollars per year in USA.  Hope this helps.
Good luck!
