Become a Ruby Professional

This module provides a thorough explanation of modern concepts for beginners. 
Beginners will get a refresher on Ruby. Those who’re already familiar with the language will rediscover object-oriented concepts, memory organization, find career advice, and save the planet from a nuclear apocalypse.
Let's tune in!

The Handbook for Ruby Developers

## Problem Statement

The robot game that we developed early in this chapter is given below. Let’s edit our game with the following changes.
 
Let the `initialize` method accept another option—the number of a robot, so this number is another parameter that defines the state of a particular robot instance. Modify the `up` and `down` methods so that these methods are no operations and do nothing if the number is odd. If the number is even, `right` and `left` methods should be no operations. Try to guess how the animation will look like with these changes.
