If it works. Frankly, I'll believe it when I see it. Even as a trained human with decades of experience turning hundreds of thousands (millions?) of pages, I still have difficulty on occasion turning one page instead of more than one, and being certain that I have done so. I'm skeptical that your device could do a better job, and suspect that it would need some feedback and error-correction add-ons before it would be something I could trust to run unattended. If it can't run unattended, and I only have one book scanner, its usefulness to me is limited. If it can't run unattended, but one operator can attend to ten scanners at once, maybe there is a commercial market.
If your prototype, when built, works as well in the real world as you hope it will, the $60 cost to manufacture might be a problem. At that price, you'll need to sell it for over $100 to be profitable. I'm not sure it would be worth it to me, as a DIY bookscanner builder, because a page turner by itself is not so useful. I'd need to automate the raising and lowering of my platen, and synchronize that with your page-turning device. I don't know how easy or difficult that would be at this point. Maybe you'd find a better market selling a $10 set of plans than a $100 device. If you're committed to manufacturing devices yourself, is the book scanner market large enough to generate economies of scale which would lower your unit costs? Would you be able to interest manufacturers of commercial scanners in licensing your device?
One promising market might be for people who are disabled, who want to read books which have not been previously scanned. They might have a need for a standalone page-turning device, if it is flexible enough to let them control when a page is turned.
The first requirement is to build a prototype that actually works. Yes, a device that can turn the pages of a book is worth building. Can you make money building one? In my opinion, it's too soon to be asking that question.
