As per the UGC guidelines, a student can't pursue two full time degree courses simultaneously. So nope! if you are thinking of the two courses simultaneously in regular mode then you will not be able to do that.

Now if you wish to pursue one course in distance education mode then you can go for it.

But as per my opinion if you want to go for Robotics just go for it or if you want to go for physics just go for it. But if you try to learn the both at a same time, then usually you will not be able to understand both the subjects as well. So you will have degree but the understanding will not be upto the mark. So I would say you should pursue one course at a time and learn it to the best level as you can. There are many physicist who works in Cognitive Science and Robotics as well as there are many Robotics engineer who work in the field of Semiconductor Physics, Nanoscience etc. So if you go to higher education your understanding will matter more. So please focus on that.

I hope this answer helps. All the very best for your future endeavors!
