I got 4567 rank in JEE mains 2022. and I am confident to get a good rank in JEE advanced. I want to pursue robotics. Should I do mechanical from IIT and then MS in robotics ? Please tell me your suggestions.

This is a very interesting question. If you want to pursue robotics further, then for now you can do either mechanical engineering from IITM, or ECE or Electrical Engineering from any Indian Institute of Technology. Nowadays there is a much better branch for UG which is Data Science and Artificial Intelligence and many good IITs like IIT Guwahati, IIT Bhilai, IIT Hyderabad and IIT Jodhpur offer it.

Going for an AI degree nowadays will be a better option that traditional branches like Mechanical due to the competitive edge they provide.
