Project: Robot Follows Typed Commands

Working in pairs, students should develop a program that includes these elements:

Together with the program, a student pair must write a paragraph that describes what tests are needed to demonstrate the program is working correctly. That is, what should a tester do to demonstrate the program works? Also, the student pair must present a sequence of steps that the tester should do to carry out the test plan. (E.g., what should be typed in a terminal window, including the details of the compile, link, and run steps?)

Command Requirements

Grading

This project will be worth 25 points, based on the following rubric:

Note

This project is planned for use as the base of a later project, so you will want to document your code well now — in anticipation of later activities.
