My Idea Is A Robot That Can Re

My idea is a robot that can read. It would help blind people and could also be a great study-buddy. Instead of looking back and forth multiple times to write down a long math equation the robot would read it for you. Even if it could only read one font and one size there could be some type of program that automatically converts everything for you, and any mistakes you can edit before you save it. I think this could really help a lot of people. I'm sure there are many more real world applications that I haven't thought of for this robot.
