something this school really needs...is a robot that helps the school(only children)

This school needs a robot that helps with anything. It is good because it would help children if they are hurt and helps children with reading, writing ,handwriting, inqury and maths. We need it because sometimes children can get hurt and bleed. It cant break and is made of metal. The robot is an expert on anything.He has lots of plasters and he won't run out. He can shrink itself and grow again!
