I would like to make a robotic

I would like to make a robotic DSLR panoramic vr head that is easily folded up to make for easy travel.

It would also be modular. The big annoyance I have with today's tech is that everything seems to be disposable rather than upgrading an old part. Also if something goes wrong with the electronics or mechanics, I would like to be able to remove that part, and clip a new one into place.
