[![Cylon.js](http://i.imgur.com/U3paNhR.png)](http://cylonjs.com)

Cylon.js is a JavaScript framework for robotics and physical computing built on
top of Node.js.

It provides a simple, but powerful way to create solutions that incorporate
multiple, different hardware devices concurrently.

## Build Status:

[![Build Status](https://secure.travis-ci.org/hybridgroup/cylon.png?branch=master)](http://travis-ci.org/hybridgroup/cylon) [![Code Climate](https://codeclimate.com/github/hybridgroup/cylon.png)](https://codeclimate.com/github/hybridgroup/cylon) [![Code Climate](https://codeclimate.com/github/hybridgroup/cylon/coverage.png)](https://codeclimate.com/github/hybridgroup/cylon)

## Getting Started

### Installation

All you need to get started on a new robot is the `cylon` module:

    npm install cylon

With the core module installed, now install the modules for whatever hardware
support you need. For the Arduino + LED blink example, we'll need the `firmata` module:

    npm install cylon-firmata

## Examples

### Arduino + LED

The below example connects to an Arduino over a serial connection, and blinks an
LED once per second.

The example requires that the Arduino have the Firmata sketch installed; which
can be obtained either through the Ardunio IDE or the `gort arduino upload
firmata` command available in [gort](http://gort.io).

```javascript
var Cylon = require('cylon');

// define the robot
var robot = Cylon.robot({
  // change the port to the correct one for your Arduino
  connections: {
    arduino: { adaptor: 'firmata', port: '/dev/ttyACM0' }
  },

  devices: {
    led: { driver: 'led', pin: 13 }
  },

  work: function(my) {
    every((1).second(), my.led.toggle);
  }
});

// connect to the Arduino and start working
robot.start();
```

### Parrot ARDrone 2.0

```javascript
var Cylon = require('cylon');

Cylon.robot({
  connections: {
    ardrone: { adaptor: 'ardrone', port: '192.168.1.1' }
  },

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

  work: function(my) {
    my.drone.takeoff();

    after((10).seconds(), my.drone.land);
    after((15).seconds(), my.drone.stop);
  }
}).start();
```

### Cat Toy (Leap Motion + Digispark + Servos)

```javascript
var Cylon = require('cylon');

Cylon.robot({
  connections: {
    digispark: { adaptor: 'digispark' },
    leapmotion: { adaptor: 'leapmotion' }
  },

  devices: {
    servo1: { driver: 'servo', pin: 0, connection: 'digispark' },
    servo2: { driver: 'servo', pin: 1, connection: 'digispark' },
    leapmotion: { driver: 'leapmotion', connection: 'leapmotion' }
  },

  work: function(my) {
    my.x = 90;
    my.z = 90;

    my.leapmotion.on('hand', function(hand) {
      my.x = hand.palmX.fromScale(-300, 300).toScale(30, 150);
      my.z = hand.palmZ.fromScale(-300, 300).toScale(30, 150);
    });

    every(100, function() {
      my.servo1.angle(my.x);
      my.servo2.angle(my.z);

      console.log(my.servo1.currentAngle() + ", " + my.servo2.currentAngle());
    });
  }
}).start();
```

### Multiple Spheros + API Server

To use the API server, first install the plugin:

    $ npm install cylon-api-http

Then it can be used in Cylon scripts:

```javascript
var Cylon = require('cylon');

// tell the API server to listen for requests at
// https://localhost:4000
Cylon.api({ port: 4000 });

var bots = [
  { port: '/dev/rfcomm0', name: 'Thelma' },
  { port: '/dev/rfcomm1', name: 'Louise' }
];

bots.forEach(function(bot) {
  Cylon.robot({
    name: bot.name,

    connections: {
      sphero: { adaptor: "sphero", port: bot.port }
    },

    devices: {
      sphero: { driver: "sphero" }
    },

    work: function(my) {
      every((1).second(), function() {
        console.log(my.name);
        my.sphero.setRandomColor();
        my.sphero.roll(60, Math.floor(Math.random() * 360));
      });
    }
  });
});

// start up all robots at once
Cylon.start();
```

## Fluent Syntax

For those more familiar with jQuery, D3, or other fluent-style JavaScript
libraries, Cylon.JS also supports a fluent syntax:


```javascript
var Cylon = require('cylon');

Cylon
  .robot()
  .connection('arduino', { adaptor: 'firmata', port: '/dev/ttyACM0' })
  .device('led', { driver: 'led', pin: 13 })
  .on('ready', function(bot) {
    setInterval(function() {
      bot.led.toggle();
    }, 1000);
  });

Cylon.start();
```

## Hardware Support

devices. The following 34 platforms are currently supported:

Our implementation of GPIO (General Purpose Input/Output) allows for a shared
set of drivers supporting a number of devices:

- [GPIO](https://en.wikipedia.org/wiki/General_Purpose_Input/Output) <=> [Drivers](https://github.com/hybridgroup/cylon-gpio)
  - Analog Sensor
  - Button
  - Continuous Servo
  - Direct Pin
  - IR Rangefinder
  - LED
  - MakeyButton
  - Motor
  - Maxbotix Ultrasonic Range Finder
  - Servo

Additionally, we also support a number of I2C (Inter-Integrated Circuit) devices
through a shared `cylon-i2c` module:

- [I2C](https://en.wikipedia.org/wiki/I%C2%B2C) <=> [Drivers](https://github.com/hybridgroup/cylon-i2c)
  - BlinkM
  - BMP180
  - HMC6352 Digital Compass
  - LCD Display
  - MPL115A2 Barometer/Thermometer
  - MPU6050

We'll also have many more platforms and drivers coming soon, [follow us on
Twitter][Twitter] for updates.

## Browser & Mobile Support

Cylon.js can be run directly in-browser, using the `browserify` NPM module. You can also run it from withing a Chrome connected app, or a PhoneGap mobile app.

For more info on browser support, and for help with different configurations, you can find more info [in our docs](/documentation/guides/browser-support).

## API

Cylon's HTTP API plugin can be used to interact with your robots remotely.

To use it, install it alongside Cylon:

    $ npm install cylon-api-http


Then, all you need to do is call `Cylon#api` in your robot's script:

```javascript
var Cylon = require("cylon");
Cylon.api();
```

Then visit `https://localhost:3000/` and you are ready to control your robots from a web browser!

<img src="http://cylonjs.com/images/screenshots/robeaux.jpg" style="margin-top: 15px; width: 100%">

You can check out more information on the Cylon API in the docs [here](http://cylonjs.com/documentation/guides/api).

## CLI

Cylon uses the Gort [http://gort.io](http://gort.io) Command Line Interface (CLI) so you can access important features right from the command line. We call it "RobotOps", aka "DevOps For Robotics". You can scan, connect, update device firmware, and more!

Cylon also has its own CLI to generate new robots, adaptors, and drivers. You can check it out at [https://github.com/hybridgroup/cylon-cli](https://github.com/hybridgroup/cylon-cli).
