Hello Hemanthsaikumarjmc

I hope you are doing good . With reference to your query, in my opinion doing BE in  mechatronics would be better option and then for masters in mechatronics. Mechatronics  is a subset of mechincal in which you are focused on automated manufacturing industry . It is specialization whereas in mechanicals you have to study electronics too which becomes difficult to do if you are not passioante about it

Hope you found this answer helpful. Good luck for your future
