Mister Rogers arrives with a device which plugs into an electrical outlet and turns things on with the clap of the hands. Demonstrating the device with a lamp, Mister Rogers sings You've Got To Do It. Mr. McFeely stops by with a small remote-controlled robot and invites Mister Rogers to join him on a visit to where people make robots. At the robot factory, Tom Zaken provides a detailed demonstration of how some of his robots work. He then takes Mister Rogers and Mr. McFeely to the assembly area to see how the robots are put together.
