Sure, unrolling toilet paper and tearing it from the roll is not difficult. But if Lego Mindstorms can do it for you, why not?
"This is a project that me and my friends built for school (UCBerkeley). Its made of lego mindstorms, scissors, and some scrap metal. With all things considered, I think it turned out alright. Not only does it fold your paper for you, it also cuts it. It would be the perfect accessory for a fancy, high-tech, Japanese bathroom!" says Kyle Yeats, creator of the clever contraption.
