Girls invent page-Turning Device

The battery-powered device, built from Legos, was created after the girls spoke with a librarian who told them some people have difficulty turning the pages of books, Tulsa World reported. The troop, who were the youngest inventors at the fair, then thought of people with arthritis or who are paralyzed and wanted to create an invention that would help them.

The Supergirls sketched out a design concept and culled through motorized Lego components and gears to figure out how to build a working prototype. They discovered that the friction from rubber Lego tires could be used to lift and turn the pages of a book. They honed the device with a second motorized component that forces pages to lay flat after being turned over.

The Supergirls’ creation was selected by the statewide FIRST program director to be the only project exhibited at an educational conference for librarians and educators in the region.

At the moment, the device only moves at one speed because it is a prototype, the girls explained, when asked by Obama if the device can slow down or speed up.

They were given the opportunity to show Obama how their Lego-made, battery-powered automatic page turner could help paralyzed or arthritic patients read books.
