CollectNewspaperKarel Solution
This lecture explains how to get started with Karel the Robot:
After watching the lecture, there are a few assignments to get you started. The first one is pretty simple and gets you to feel comfortable with the basics:
Here is my solution:
<pre>/* * File: CollectNewspaperKarel.java * -------------------------------- * At present, the CollectNewspaperKarel subclass does nothing. * Your job in the assignment is to add the necessary code to * instruct Karel to walk to the door of its house, pick up the * newspaper (represented by a beeper, of course), and then return * to its initial position in the upper left corner of the house. */ import stanford.karel.*; public class CollectNewspaperKarel extends SuperKarel { public void run () { MoveToNewspaper (); PickUp (); Return (); } private void MoveToNewspaper () { move (); move (); turnRight (); move (); turnLeft (); move (); } private void PickUp () { pickBeeper (); turnAround (); } private void Return () { for (int i = 0; i &lt; 3; i++) { move(); } turnRight (); move (); turnRight (); } }</pre>
I’m sure there are a few solutions to this, but, most importantly, this solves the problem when it runs! I was extremely proud of accomplishing my first little program 🙂
But I’m open to tips. Let me know if you see something that I can improve and apply to the next assignments.
