I don't think robots will completely replace teachers in schools. Robots can assist students by explaining lessons, providing quick answers and grades students’ tests. However, teachers play a far more important role because they understand students' emotions and can motivate them when they feel tired or confused. Teachers also create a positive and interactive learning environment. In my opinion, robots are useful tools, but human teachers are still number one.
