Idol program

Performer Robot

Who is the Robot performer?

• Imagine a checkered field (like a sheet from a notebook with a checkered pattern) on which there is a certain object, which we will call a Robot. Using special teams, we can control this Robot - move it around the cells, paint over the cells. And in most cases, our task will be to write a program for the Robot, in which it will paint certain cells.

Setting up the environment Idol for the performer Robot

• The launched Idol program looks like this.

Starting situation Robot

• Before starting the program execution, it is necessary to set the starting environment for the Robot executor. This means placing the Robot in the desired position, placing walls, painting the required cells, etc. This step is very important. If you ignore it, the program may not work correctly or even crash.

Performer Robot. Simple commands.

• up
• down
• left
• right
• paint over

The result of executing these commands is clear from their names:

• up - move the Robot up one cell
• down - move the Robot one cell down
• left - move the Robot one cell to the left
• right - move the Robot one cell to the right
• paint over - paint over the current cell (the cell in which the Robot is located).

Algorithm example

• First you need to write the phrase:
• use Robot

If you know how many cells need to be painted, then the solution algorithm will be as follows!

Task No. 1

• Write a program to solve the following problem if you know how many cells need to be shaded

Cycles

• 1. Loop with counter used when it is known in advance how many repetitions need to be done.

nc time

Performer Robot

KuMir programming environment

Often in lessons and in task 20.1 the “Robot” performer is required to go down or up the stairs. You must understand that going up or down the stairs is carried out one cycle. As a rule, to check the performance of the algorithm, it is necessary to add steps on the ladder. The algorithm must be executed regardless of the number of stages, for example, both for two stages and for twenty.

TASK

In an infinite field, there is a horizontal wall that continues indefinitely to the left and ends with a staircase that goes down from left to right. The height of each step is two squares, the width is two squares. The robot is on a horizontal wall to go down the stairs. The figure shows one of the ways to position the ladder and the Robot (the Robot is indicated by the symbol ◊ ).

Write an algorithm for the Robot that paints all the cells located on the steps of the stairs. It is required to paint only the cells that satisfy this condition.

For example, for the above drawing, the Robot must color the cells:

The final location of the Robot can be arbitrary. The algorithm must solve the problem for an arbitrary field size and any number of steps. When executing the algorithm, the Robot should not be destroyed.

SOLUTION

We will solve this problem in the KuMir programming environment. Open the program and go to the Robot menu -> Edit environment

We are building a staircase. With the left mouse button we click on the walls of the cage. Move the diamond (robot) to the desired location by holding left button mice

Exit the editing mode of the Robot menu -> Edit environment. Next, write the command “use Robot” on the first line.

First, let's remember some commands for the Robot performer.

The assignment says that

The algorithm must solve the problem for an arbitrary field size and any number of steps

This means that the Robot must move using the While loop. We reason like this: there is a wall below the robot, which means it is not free from below. On the 4th line of the editor we write the command

nts is not free from below yet.

Inside the loop, you need to execute the commands sequentially:

To the right, down, paint to the right, to paint, to the left, to bottom, to paint, to the right, to paint

Fully ready-made program looks like that:

Use Robot alg start nc until the bottom is free right down paint right paint left down paint right paint kts end

To test the algorithm, let’s add a few more steps and check the result

So, the algorithm paints cells for any number of steps on the ladder.

Driver Robot is comprehensive solution for installation and update system drivers. The application has an extremely pleasant ergonomic interface and is extremely easy to use. The program allows you to radically simplify the selection and installation process necessary drivers for all system devices and periphery. Immediately after launch, the utility will analyze your system and detect all existing and connected equipment.
