eg: 
http://ruby.about.com/od/Automation-and-FFI/fl/Automating-with-Robot.htm

Use JRuby if you want to implement Robot class:

require 'rubygems'
require 'Selenium-webdriver'
require 'java'
java_import 'java.awt.Robot'
java_import 'java.awt.event.InputEvent'
java_import 'java.awt.event.KeyEvent'
class WatirTest
#  browser = Watir::Browser.new :firefox
  browser = Selenium::WebDriver.for :firefox
  browser.get 'http://gmail.com'
  sleep 3
  browser.find_element(:id, 'Email').send_keys 'vicky.venu81'
#  puts browser.execute_script("return document.body").inspect

  robot = Robot.new
 
  robot.key_press(KeyEvent::VK_ENTER)
  puts robot.methods
#  robot.mouseMove(963,10);

#  browser.quit
end

Working eg: 2
require 'java'
java_import 'java.awt.Robot'
java_import 'java.awt.event.InputEvent'
java_import 'java.awt.event.KeyEvent'

class RobotTest
  def testing
    x = 'a'
    puts x.ord
    
    puts "ASCII value of 'a': #{'a'.ord}"
    puts "ASCII value of 'z': #{'z'.ord}"
   
    puts "ASCII value of 'A': #{'A'.ord}"
    puts "ASCII value of 'Z': #{'Z'.ord}"
   
    word = "abcdefg"
    word.each_byte {|b| print b.chr }
    puts '+++++++++++++++++'
    sleep 5
    word.each_byte do |chr|
      puts chr
      robot = Robot.new
      code = chr-32
      robot.key_press(code)
    end
  end
end

RobotTest.new.testing()
 
Output:
97
ASCII value of 'a': 97
ASCII value of 'z': 122
ASCII value of 'A': 65
ASCII value of 'Z': 90
abcdefg+++++++++++++++++
97
98
99
100
101
102
103

if wanted to implement additional methods using Robot class, ref the below the example in java:

public class JavaRobotExample

{

  Robot robot = new Robot();

  public static void main(String[] args) throws AWTException

  {

    new JavaRobotExample();

  }

   

  public JavaRobotExample() throws AWTException

  {

    robot.setAutoDelay(40);

    robot.setAutoWaitForIdle(true);

     

    robot.delay(4000);

    robot.mouseMove(40, 130);

    robot.delay(500);

    leftClick();

    robot.delay(500);

    leftClick();

    robot.delay(500);

    type("Hello, world");

    robot.mouseMove(40, 160);

    robot.delay(500);

    leftClick();

    robot.delay(500);

    leftClick();

     

    robot.delay(500);

    type("This is a test of the Java Robot class");

     

    robot.delay(50);

    type(KeyEvent.VK_DOWN);

     

    robot.delay(250);

    type("Four score and seven years ago, our fathers ...");

    robot.delay(1000);

    System.exit(0);

  }

   

  private void leftClick()

  {

    robot.mousePress(InputEvent.BUTTON1_MASK);

    robot.delay(200);

    robot.mouseRelease(InputEvent.BUTTON1_MASK);

    robot.delay(200);

  }

   

  private void type(int i)

  {

    robot.delay(40);

    robot.keyPress(i);

    robot.keyRelease(i);

  }

  private void type(String s)

  {

    byte[] bytes = s.getBytes();

    for (byte b : bytes)

    {

      int code = b;

      // keycode only handles [A-Z] (which is ASCII decimal [65-90])

      if (code > 96 && code < 123) code = code - 32;

      robot.delay(40);

      robot.keyPress(code);

      robot.keyRelease(code);

    }

  }

}
