difficult jobs. Some robots do regular jobs. Bobby, the mail carrier , brings mail to a large office building

       Mr Leachim , who weighs two hundred pounds and is six feet tall,has some advantages as a teacher. One is that he does not forget details.  He knows each child's name, the parents' names and what each

child knows and needs to know. Except that,he knows each child's petsand hobbies. Mr Leachim does

not make mistakes.  Each child goes and tells him his or her name,  then dials and an ID number.   His

computer brain puts the child's voice and number together. He identifies the child with no mistakes. Then

he starts the lesson.

they can move switches. In this way they can repeat Mr Leachim's lesson over and over again.When the

children do a good job,  he tells them something interesting abouttheir hobbies.  At the end of the lesson

the children switch Mr Leachim off.
