In the early 2050's, Na Robotics began designing a huge amusement park to be built near Colorado. It intended the park to have educational as well as amusement value and to entertain adults and their children. The company aptly called it the Ai and Robot World -- this is an amusement park for vacationers, it provides its customers a way to live out their fantasies through the use of AI and robotic technology that provide anything they want. The features of the robot theme park were kept a secret from the public, and no one knows what is contained in the 100 feet steel doors. Today two visitors won tickets to this special park: Jackson and his little brother David, 17 years old and 7 years old respectively.
