# Crazyflie

For this Cylon demo, we're going to connect to a Crazyflie, and then make it
take off and land. Before we get started, make sure you've got the
`cylon-crazyflie` adaptor installed.

To start us off, let's import Cylon:

    var Cylon = require('../..');

Now that we've got that set up, we can start defining our robot:

    Cylon.robot({

We'll be using one connection and one device for this robot, both using the
crazyflie adaptor. We'll be connecting to the Crazyflie using the CrazyRadio.

      connections: {
        crazyflie: { adaptor: 'crazyflie', port: "radio://1/10/250KPS" }
      },

      devices: {
        drone: { driver: 'crazyflie' }
      },

With the parts in place, we can start defining our robot's work.

      work: function(my) {

When our drone is ready, we'll make it takeoff. After ten seconds, we'll tell it
to land, and five seconds after that to stop.

        my.drone.on('start', function() {
          my.drone.takeoff()
          after((10).seconds(), my.drone.land);
          after((15).seconds(), my.drone.stop);
        });
      }

With all that done, we can start up the robot and get the Crazyflie flying:

    }).start();
