     var Cylon = require('../..');
 
+For easier use later, let's define the colors we'll be using with the Spheros,

+
+    var Green = 0x0000FF,
+        Red = 0xFF0000;
+
 We'll be using four robots for this example, but they'll have very similar
 programming so we just need to define what's different between them for now.
 Each of the robots will have a unique name, and will communicate on their own
 port.
 
-    var bots = [

-      { port: '/dev/rfcomm0', name: 'Thelma' },

-For easier use later, let's define the colors we'll be using with the Spheros,
-green for alive and red for dead:
-
-    var Green = 0x0000FF;
-    var Red = 0xFF0000;
 
 That gets the basics out of the way.
 
 Since, as previously mentioned, our robots all have the same basic
-functionality, we can define that functionality in a CoffeeScript class. Since
+functionality, we can just loop over the `bots` object, and create robots as we
-we're feeling particularly creative today, let's call this class `ConwayRobot`:
+go.
 
-    var ConwayRobot = (function() {
+    Object.keys(bots).forEach(function(name) {
-      function ConwayRobot() {}
+      var port = bots[name];
 
 All of our robots will be connecting to a Sphero, and be operating via a single
 device (you guessed it, a Sphero).
 
-      ConwayRobot.prototype.connection = { name: 'Sphero', adaptor: 'sphero' };
+      Cylon.robot({
-      ConwayRobot.prototype.device = { name: 'sphero', driver: 'sphero' };
+        name: name,
+
+        connection: { name: 'sphero', adaptor: 'sphero', port: port },
+        device: { name: 'sphero', driver: 'sphero' },
+
+Now that the pieces are there, we can set up our robot's work. It starts by
+being "born", then moves every three seconds if it's alive, celebrates it's
+birthday every ten seconds, and increments it's contacts every time the Sphero
+detects a collision.
+
+        work: function(my) {
+          my.born();
+
+          my.sphero.on('collision', function() {
+            my.contacts += 1;
+          });
+
+          every((3).seconds(), function() {
+            if (my.alive) {
+              my.move();
+            }
+          });
+
+          every((10).seconds(), function() {
+            my.birthday();
+          });
+        },
+
+When a robot is asked to move, it rolls in a random direction at speed 60.
+
+        move: function() {
+          this.sphero.roll(60, Math.floor(Math.random() * 360));
+        },
 
 When the robots are first started, they are born. This sets their contacts to
 zero, their age to zero, makes them "alive", and starts them moving for the
 first tick.
 
-      ConwayRobot.prototype.born = function() {
+        born: function() {
           this.contacts = 0;
           this.age = 0;
           this.life();
           this.move();
-      };
+        },
-
-When a robot is asked to move, it rolls in a random direction at speed 60.
-
-      ConwayRobot.prototype.move = function() {
-        this.sphero.roll(60, Math.floor(Math.random() * 360));
-      };
 
 In the case of our robots, "life" just means the robot's internal "alive" state
 is set to `true`, and the Sphero's LED is set to green.
 
-      ConwayRobot.prototype.life = function() {
+        life: function() {
           this.alive = true;
           this.sphero.setRGB(Green);
-      };
+        },
 
 Similarly, "death" just sets the "alive" state to false, the Sphero's color to
 red, and stops the Sphero from moving.
 
-      ConwayRobot.prototype.death = function() {
+        death: function() {
           this.alive = false;
           this.sphero.setRGB(Red);
           this.sphero.stop();
-      };
+        },
 
 A robot is decided to have enough contacts if it has between two and six
 contacts.
 
-      ConwayRobot.prototype.enoughContacts = function() {
+        enoughContacts: function() {
-        return (this.contacts >= 2 && this.contacts < 7);
+          return this.contacts >= 2 && this.contacts < 7;
-      };
+        },
 
 On a robot's birthday, it increments it's age, prints it's name, age, and
 contacts to the console, and then determines if it's now alive or dead based on
 the number of contacts it had in the last tick.
 
-      ConwayRobot.prototype.birthday = function() {
+        birthday: function() {
           this.age += 1;
 
+          if (this.alive) {
             console.log("Happy birthday, " + this.name + ". You are " + this.age + " and had " + this.contacts + " contacts.");
+          }
 
           if (this.enoughContacts()) {
-          if (this.alive == null) { this.rebirth(); }
+            if (!this.alive) {
+              this.born();
+            }
           } else {
             this.death();
           }
 
           this.contacts = 0;
-      };
-
-Now that the pieces are there, we can set up our robot's work. It starts by
-being "born", then moves every three seconds if it's alive, celebrates it's
-birthday every ten seconds if it's alive, and increments it's contacts every
-time the Sphero detects a collision.
-
-      ConwayRobot.prototype.work = function(me) {
-        me.born();
-
-        me.sphero.on('collision', function() {
-          this.contacts += 1;
-        });
-
-        every((3).seconds(), function() {
-          if (me.alive != null) { me.move(); }
-        });
-
-        every((10).seconds(), function() {
-          if (me.alive != null) { me.birthday(); }
-        });
-      };
-
-      return ConwayRobot;
-    })();
-
-Now that we've defined the behaviour of our Conway's Game robots, we can make
-the robots themselves.
-
-For each of the sets of unique characteristics in the earlier `bots` array,
-we'll create a new `ConwayRobot`, assign it it's unique characteristics, and
-pass it to Cylon so it will keep track of them.
-
-    for (var i = 0; i < bots.length; i++) {
-      var bot = bots[i];
-      var robot = new ConwayRobot;
-
-      robot.connection.port = bot.port;
-      robot.name = bot.name;
-
-      Cylon.robot(robot);
         }
+      });
+    });
 
 Now that Cylon knows about our robots and what they do, we can get started!
