It’s a gentle way to teach object-oriented
programming that really is “objects first”.
It’s an implementation of Rich Pattis’
Karel the Robot.
It goes way beyond traditional implementations of
Karel by targeting the entire introductory programming course, not just
the first two weeks.
It’s not just robots! Other examples include
graphics, a credit card, a combination lock, graphing polynomials, input and
output for a game of Connect4, an on-line telephone book, recordkeeping for Big
Brothers/Big Sisters, and using classes from the Java library.
