HI Aryan,

It totally depends upon your interest and passion. If you are interested in machines and how they are made or how they work mechanical engineering would be the best choice for you. Now, if you are interested in AI or future technologies like robotics and have affinity towards programming then you should go for Automation and Robotics.

Refer here for more info about Automation and Robotics - Automation and Robotics Courses, Subjects, Colleges, Syllabus, Scope, Fees, Eligibility (careers360.com)

If you want my opinion and then Automation and Robotics is a better course.
