Karel 15a
Complete the following in class or for homework. Do NOT hand in your work unless other instructions were given.
| 1. | Karel is in a completely enclosed rectangular
room that has, unfortunately, litter strewn all over it (see the sample room
given below). Create a new class of robot that can pick up the litter. This
robot is a child of Robot. The room is always 4 intersections wide and 3 intersection high. Karel always starts in the top-left corner and maybe facing any direction. You must turn and face east before you start cleaning up. Karel should move back to its starting location when its task is complete. It should then face north. Examine the Robot documentation to find out how to make the city display the number of things that are on each intersection. You must make one new method that will pick up all of the items that are on the intersection. You can assume that there is no more than 4 pieces of litter on any intersection. As you move the robot in the city, use the new method on each intersection. Create two different city files that contain:
so that you can test your robot. |

| 2. | Build another version of LitterBot that is called
LitterBotSE and extends RobotSE. Examine the Robot documentation to find out easier ways of having this robot clear the room. |
