Robot

This project is an educational Robot simulator for learning basic programming and algorithms. Students write short Python programs that move the Robot on a grid, paint cells, read the environment, and complete small tasks with immediate visual feedback in a desktop window.

It is intended for school students and anyone beginning to learn programming: sequencing, loops, conditions, and simple problem solving in a friendly, game-like setting.

Website: robot.stepindev.com – task catalog, command reference, and articles.

Example: task intro8

Task: Move the Robot onto the cell with the house, painting every marked cell along the way.

Sample solution in Python:

from robot import *

task("intro8")

move_down()
paint()
move_right()
paint()
move_up()
paint()
move_right()
paint()
move_down()

Robot commands

paint()
Paints the current cell.

is_free_left()
Returns True if there is no wall on the left.

is_free_right()

Using the distributed module

1. Download the module archive from the GitHub Releases page.
2. Extract the archive into the student’s working folder.
3. Save your solution file next to the robot module. Use sample_solution.py from the archive as a starting point.
4. To run a different exercise, change the string passed to task() (see the Available tasks for task() section above).

Requirements: Python 3.7+ with the standard library (the UI uses tkinter, which is included with most Python installations on desktop systems).
