Thank you Soeren, I'll look for it.
I need a very simple device, just to grab a single page of a book, in other words, it will touch the paper, no problem with the distance, no problem making a robot arm to touch the paper and move the pick along an angle. It shouldn't be too big, of course.
I just don't know how to do that without put a DC motor spining an acrylic cilinder over a piece of wool.
