Im studying chemical engineering(Bsc).But I want to be a mechatronics engineer.Is it possible?

After you get your degree you will mostly be supervising people, so it doesn't make much difference what kind of an engineering degree it is. You can learn the basic mechanical stuff in a couple of months and pick up the rest as you go along.

Scientists study how things work.
Engineers study how to make things.
Technicians study how to make things work.
