}

index.php

<?php

$loader = new \Phalcon\Loader();

$loader->registerDirs(array('controllers/'))->register();

$app = new Phalcon\Mvc\Micro();

$robotsController = new RobotsController();

//Retrieves all robots
$app->get('/', array($robotsController, 'index'));

$app->get('/robots', array($robotsController, 'index'));

$app->get('/robots/show/{id}', array($robotsController, 'show'));

$app->handle();

but we cannot use service from $di in controller, Im already done with that.. still not work to access $this->response or $this->request from controller ....
