Karel The Robot Learns Python How To Write Programs

They learn basic commands, the repeat loop, if-else conditions, the while loop, and finally user-defined commands.FANUC Robot Software Options. Starting with simple keystrokes in Game 1, learners move on to typing lines of code to create and run programs. Karel the Robot teaches learners how to write programs using the Karel programming language, which is based on Python.

To do so, follow these steps within your repl: Click the 'Packages' tab. Additionally, when using repl.it, you may have to import manually. Some IDEs (such as PyCharm) might be able to automatically run this command if you type the import sequence.

It has a lot of terribly useful information. Before you start on this assignment, make sure to read Handout Using Karel with PyCharm. There is a starter project including all of these problems on the CS106A website under the вЂњAssignmentsвЂќ tab. Design machines and roller coasters, build towers with robots.This assignment consists of four Karel programs (and one extra credit optional program). Based on problems by Nick Parlante and Eric Roberts, lovingly modified by your current CS106A staff.The Bible App for Kids is a great way for your children to learn Biblical stories about.

Problem 1 (CollectNewspaperKarel.py)Your first task is to solve a simple story-problem in KarelвЂ™s world. You may not use other features of Python (including variables, parameters, break, and return), even though the PyCharm-based version of Karel accepts them. There is also a bonus problem described at the end that is optional to complete, as well as other suggestions for extensions you can complete for this assignment.Please remember that your Karel programs must limit themselves to the language features described in the Karel the Robot Learns Python reader. If you discover an error after youвЂ™ve made a submission, just fix your program and submit a new copy.The four Karel problems to solve are described on the following pages. Remember that you can submit more than one version of your project, but only the most recent submission will be graded.

You must get Karel to pick up the newspaper located outside the doorway and then to return to its initial position.This exercise is simple and is meant to help you get you started programming with Karel. The newspaper, like all o=bjects in KarelвЂ™s world, is represented by a beeper. The problem you need to solve is to get Karel to collect the newspaper. During this time, you might correctly surmise that Karel is sheltering-in-place.KarelвЂ™s starting state for CollectNewspaperKarelKarel starts off in the northwest corner of its house as shown in the diagram.

Problem 2 (RampClimbingKarel.py)Write a program that has Karel draw a diagonal line acrossAn example end state of Karel walking up a ramp.The key to drawing a diagonal line with slope ВЅ is to move two steps forward and one step up between each beeper. Note that all Karel worlds are located in the worlds folder in the Assignment 1 project folder. In your solution, include a function for each of the three steps shown in the outline above.Your program should run successfully in the following world:CollectNewspaperKarel.w (default world. Thus, all you have to do is write the sequence of commands necessary to have Karel:Although the program does not have many lines of code, it is still worth getting some practice with decomposition.

You may assume that the world is an odd number of columns across Karel always begins at the bottom left corner of and empty world facing East. Solving the problem for even columns as well is much harder and would count as an 'extension'.

The columns are always exactly four Avenues apart, so they would be built on 1st Avenue, 5th Avenue, 9th Avenue, and so on. The first column should be built on 1st Avenue. Karel starts at the corner where 1st Avenue and 1st Street meet, facing east, with an infinite number of beepers in KarelвЂ™s beeper bag. There are several example worlds in the starter folder, and your program should work correctly in all of them.When Karel is done, the missing stones in the columns should be replaced by beepers, so that the final picture resulting from the initial world shown in Figure 5 would look like the illustration below.Karel should repair the Main Quad to a structurally sound state after completion.KarelвЂ™s final location and the final direction Karel is facing at the end of the run do not matter.Karel may count on the following facts about the world: In particular, Karel should repair a set of arches where some of the stones (represented by beepers, of course) are missing from the columns supporting the arches, as illustrated in the figure below.An initial example world with broken arches that StoneMasonKarel must repairYour program should work on the world shown above, but it should be general enough to handle any world that meets the basic conditions outlined at the end of this problem. The world is always square (the world's height is the same as its width)Your third task is to repair the damage done to the Main Quad in the 1989 Loma Prieta earthquake.

Avenues that will not have columns will never contain existing beepers.You should make sure your program runs successfully in all of the following worlds (which are just a few different examples to test out the generality of your solution):StoneMasonKarel.w (default world), SampleQuad1.w, SampleQuad2.wNote that all Karel worlds are located in the worlds folder in the Assignment 1 project folder. Your program should not put a second beeper on corners that already have beepers. In an initial world, some columns may already contain beepers representing stones that are still in place. However, Karel cannot assume that columns are always five units high, or even that all columns within a given world are the same height. The top of a beeper column will always be marked by a wall. Although this wall appears after 13th Avenue in the example figure, your program should work for any number of beeper columns.

The starter code folder contains several sample worlds with these special cases, and you should make sure that your program works for each of them.This problem is hard: Try simplifying your solution with decomposition. Some examples of such cases are discussed below.Odd-sized checkerboards are tricky, and you should make sure that your program generates the following pattern in a 5x3 world:Karel should generate this checkerboard pattern for a 5x3 world.Other special cases you should consider are worlds with only a single column or a single row. As you think about how you will solve the problem, you should make sure that your solution works with checkerboards that are different in size from the standard 8x8 checkerboard shown in the example above. (KarelвЂ™s final location and the final direction it is facing at the end of the run do not matter.)The beginning and end states for CheckerboardKarel.This problem has a nice decomposition structure along with some interesting algorithmic issues.

Along the way, Karel is allowed to place additional beepers wherever it wants to, but must pick them all up again before it finishes. For example, say Karel starts in the 5x5 world pictured in the figure:An example beginning state for MidpointKarel.Karel should end with Karel standing on a beeper in the following position:The corresponding end state for MidpointKarel.Note that the final configuration of the world should have only a single beeper at the midpoint of 1st Street. Note that all Karel worlds are located in the worlds folder in the Assignment 1 project folder.Optional Bonus Problem (MidpointKarel.py)As an exercise in solving algorithmic problems, program Karel to place a single beeper at the center of 1st Street (aka Row).

If the width of the world is odd, Karel must put the beeper in the center square. The world need not be square, but you may assume that it is at least as tall as it is wide.Your program, moreover, can assume the following simplifications: The initial state of the world includes no interior walls or beepers. Karel starts at the bottom left corner, facing east, with an infinite number of beepers in its bag.
