Solutions
Problem I. Intelligent Agents [15 Marks]
1. Consider an intelligent chess-playing robot (a robot, NOT just a software). For this robot and
its task environment, answer the following questions and justify your answers. [Note: There is not
necessarily a “right” answer to each question. The answer can depend on your problem definition
and assumptions. So state them clearly].
a. [5 marks] What is meant by PEAS? Give a PEAS description of the task environment.
Performance measure: % of wins, playing a decent game of chess, etc.
Environment: Chess board, pieces, opponent, etc.
Actuators: Arm, gripper, etc.
Sensors: Camera, arm joint sensor, etc.
b. [2 marks] Is this a fully or partially observable environment? Justify your answer.
Fully observable – since the robot can always see the board with the chess pieces.
[“Partially observable, since the robot cannot see everything in the overall environment” is
also a valid answer. However, “It is partially observable because we can’t read the opponent’s
mind” is not a valid reason]
