I Propose A Robot That Would H

I propose a robot that would help in assisting school teachers in paper corrections. Everyone knows that exams are necessary but if there is an answer key for an exam and someone has to sit and correct all the answers that is very tedious. Instead we can have a robot correct the papers by scanning the students paper and writing the total and points assigned for the question. He can read through his camera and interpret the results in his micro controller while doing math to assign the total which will reduce calculation errors. He can also upload the scores to the course learning website that the school uses. May be he can even go in and teach the students. I think this would be a brilliant and beneficial innovation
