First after 10th you have to go for 12th with science stream. Then you have to qualify for entrance examination of engineering and after that you can take admission in Robotics or AI or Computer Science and Engineering courses. For IIT's, NIT's you have to qualify JEE MAINS & ADVANCED and for anyother colleges you have to appear in their own organized entrance examinations like VITEEE for Velore Institute of Technology or State JEE's for state government engineering examinations.
