Add the following text to the end of the rule “Visitors”:

An NPC is any Visitor controlled by the Proprietor other than the one named “Grandpa Fuller”.

Create a subrule to “Visitors” named “The Robot” with the following text:

There is an NPC named “Bucky Bot”, who is the Robot . At any given time, one Group is the Robot Operator, defaulting to the Proprietor; this is publicly tracked. The Robot Operator may cause the Robot to take Traffic Actions as though they controlled the Robot. The Proprietor, unless he is also the Robot Operator, may not cause the Robot to take Traffic Actions.

Add a subrule to “Attractions List” called “Robot Race”, with the following text:

The Robot Race is a Queue. Its Front Effect is “Admit 1: their Group becomes the Robot Operator.”

Create the “Bucky Bot” visitor under the Proprietor’s control.
