JavaScripting

Cylon.js is a JavaScript framework for robotics, physical computing, and the Internet of Things (IoT).

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

Build Status:

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, gpio, and i2c modules:

npm install cylon-firmata cylon-gpio cylon-i2c

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.

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

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)

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 + HTTP API Plugin

To use the HTTP API plugin, first install it's NPM module:

$ npm install cylon-api-http

Then it can be used in scripts:

var Cylon = require('cylon');

// tell the HTTP API plugin to listen for requests at https://localhost:4000
Cylon.api("http", { 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 chainable syntax:

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();

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.

API Plugins

Cylon.js has support for different API plugins that can be used to interact with your robots remotely. At this time we have support for http/https, mqtt, and socket.io with more coming in the near future.

To use an API plugin, install it alongside Cylon:

$ npm install cylon-api-http cylon-api-socketio

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

var Cylon = require("cylon");

// For http
Cylon.api('http');

// Or for Socket.io
Cylon.api('socketio');

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

You can check out more information on the Cylon API in the docs here.

CLI

Cylon uses the Gort 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.

Documentation

We're busy adding documentation to our website, check it out at cylonjs.com/documentation.

If you want to help with documentation, you can find the code for our website at on the https://github.com/hybridgroup/cylon-site.
