Robby the Automaton is a robot used to promote the Springfield Knowledgeum. He is brought to Edna Krabappel's class telling the students about the Knowledgeum. He was believed to speak and move by himself, but Bart saw the man controlling the robot from outside the classroom. When Bart knocked out the man by throwing an apple at him, the robot reverted to default setting ("Crush! Kill! Destroy!") and started strangling Skinner, much to the students' amusement.
