Programming Logic and Design, Introductory 7th Edition by Joyce Farrell

Exercise 9

Assume that you have created a mechanical robot that can perform the following tasks:

• Stand up.

• Sit down.

• Turn left 90 degrees.

• Turn right 90 degrees.

• Take a step.

Additionally, the robot can determine the answer to one test condition:

• Am I touching something?

a. Place two chairs 20 feet apart, directly facing each other. Draw a structured flowchart or write pseudocode describing the logic that would allow the robot to start from a sitting position in one chair, cross the room, and end up sitting in the other chair. Have a fellow student act as the robot and carry out your instructions.

b. Draw a structured flowchart or write pseudocode describing the logic that would allow the robot to start from a sitting position in one chair, stand up and circle the chair, cross the room, circle the other chair, return to the first chair, and sit. Have a fellow student act as the robot and carry out your instructions.
