Reeborg the Robot   Fundamentals

• Reeborg's World
• Reeborg's Capabilities
• Reeborg's Jobs

Reeborg's World

• is bounded on the sides by impenetrable boundary walls.
• contains horizontal streets (running east-west) and vertical avenues (running north-south).
• can contain interior wall sections that are positioned between adjacent street corners and prevent Reeborg from moving directly between these street corners.
• can contain beepers, small plastic tokens emitting a quiet beeping noise that Reeborg can sense, on any street corner.

One (example) arrangement of Reeborg's world is given below:

Reeborg's Capabilities

• SIGHT: three video cameras focused to detect walls immediately to the left, right, and straight ahead.
• SOUND: a microphone to hear if there are any beepers on the corner that Reeborg is on.
• DIRECTION: an internal compass to determine Reeborg's direction, either North, South, East, or West.
• TOUCH: Reeborg has a soundproof pocket and has a mechanical arm to pick up beepers and place them in the pocket or remove them from his pocket and place them on the street corner. Reeborg can use this mechanical arm to detect if the bag contains beepers.

Reeborg's Jobs

• Reeborg's jobs can be very different. They generally consist of a task we want Reeborg to do, and a situation that describes exactly the current state of Reeborg's world (where are walls and beepers, where is Reeborg, how many beepers are in his pocket, etc.) Here is an example:

Every morning Reeborg is awakened in bed when the newspaper - represented by a beeper - is thrown on the front porch of the house. Program Reeborg to retrieve the paper and bring it back to bed. The newspaper is always thrown to the same spot, and Reeborg's world, including his bed, is as pictured.
