If your college provide you an opportunity to take optional subjects on robotics and artificial intelligence then you can opt for them. However if this is not the case then you can take online courses on artificial intelligence and embedded system and further can take a project on it by asking your college faculties. If you work honestly then you can take letter of recommendation from the professor of your college and then take internship in some reputed University abroad 

If you did not get any opportunity in the graduation then once you complete your graduation you can go for higher studies in the field of your interest.
