Management Question

Question 1:

A robot is capable of delivering parcels from one location to another location. To describe the environment of the robot, we introduce the following predicates:

robot_at(l): the robot is located at location l.

parcel_at(p,l): the parcel p is located at location l.

handfree: the robot does not hold any parcel.

holding(p): the robot is holding parcel p.

The robot can perform three actions: Grab, Goto and Drop. The following table provides the STRIP specification of the actions:

Assume that the initial state of environment is:

robot_at(l1), parcel_at(p1, l1), parcel_at(p2, l1), handfree

the goal of the robot is:

parcel_at (p1,l2), parcel_at (p2,l2), robot_at(l1).

Generate a run that brings the initial state to the goal states (10%). Depict the details of state transformation alone the run by indicating what facts are added and what facts are deleted after each action that is performed (10%)¹.

Question 2 :

Download the GDL description for Eight Puzzle (eightPuzzle.txt). Read the description and answer the following questions:

• According to the game description, write the initial states of the game.
• According to the game description, write the goal states of the game (i.e., the states with goal value 100)?
• According to the game description, what are the possible actions “you” as a robot can take (legal actions)?
• Write action descriptions in STRIPS.
• Define a utility function (over states) for a game player (or called heuristic function) .
• Assume that the initial state changes to

Write a plan for the robot to achieve its goal.
