• What IoT IS and IS NOT?

• Computer Intelligence

• Azure Cognitive Services

• Demo

• Tessel v2 “Thing”

• Node.js for “Things”

• “Thing” in Action

Nov 19, 2016

What is (NOT) IoT

• A $1.5 trillion market by 2020

“… A network of networks

of uniquely identifiable endpoints (‘things’)

that communicate locally or globally

using IP connectivity

without human interaction …”

International Data Corporation (IDC)

• A “Thing”?o IP is not enough

o Does not require human interaction

o Often w/o display

o Machine makes a decision rather than human

Nov 19, 2016

Collect – Communicate – Analyse – Act

IoT would not work w/o AI

• How to make IoT?

• More sensors = Seas of data

• Just data has no value

AI provides tools to go beyond

trivial real-time IoT use cases

AI Engines are:

• Sophisticated

• Time consuming

• Expensive

How to make IoT work?

Microsoft Cognitive Services

• Give your applications a human sideo Intelligent APIs and SDKs

o On top of Microsoft Machine Learning API

• Initially “Project Oxford”o Announced on “Build 2015”

• Pricingo All APIs have free plans available

• Samples & Documentationo https://www.microsoft.com/cognitive-services/en-us/apis

Vision API

Allows computers to understand images and video

• Computer Vision

• Emotion

• Faceo Recognize faces and emotions

o Group faces that are alike

o Verify two faces are the same

o Computer vision

Nov 19, 2016

Cognitive Services (Highlights)

• Speecho Convert Audio (Mic, File) <-> Text (28 languages)

o Speaker Verification & Identification

• Languageo Language Understanding (Intent)

o Sentiment Analysis

o Topic detection

• Knowledgeo Entity Linking

o Recommendations – Frequently bought together, Item to Item recommendations

Nov 19, 2016

DEMO

Nov 19, 2016

IoT Challenges?

• Non-proprietary technologies

• Keep costs reasonable

• CPU revolution

• Network revolution

• Battery revolution ?

Nov 19, 2016

IoT from Cloud to Fog

• Cloud Computingo Complex services accessible over the web

o Rent resources (storage, power, processes)

o Minimal management effort

• Cloud computing issues?

• Fog Computingo Lower cost of HW

o Cloud services moved to the ground

• Fogging advantageso Lower latency

o Better QoS and UX

o Improved security

• Smart Gateways

Nov 19, 2016

Hardware built for the web

Nov 19, 2016

• By Technical Machine (2013)

• Crowd funded at Dragon Innovation platform

It is…

• 2nd gen Internet connected microcontroller

• Programmable in JavaScript

• compatible

• WiFi programmable

• Open source HW and SW

Production or just Playing?

• Costs add up in scaleo Element14(PI), Seeed Studio (Tessel) allow mass production customizations

• Availability and quantity

• Support and maintenance

• Reliability & Securityo SD card (PI) – system may not boot, card can be replaced

o What is the worst thing to happen if controller stops?

o Heat, moisture, dust, vibration, power loss…

• Programmable logic controller (PLC)o Designed for rougher environments

o Have 2-5x longer lifespan

o Tight tolerance on performance

o Non-popular programming languages

Nov 19, 2016

JavaScript for IoT

• Widely usedo Strong community and ecosystem

o Standardized (ECMAScript 5, 6, 7)

• High-level languageo More productive

• Suited to embedded deviceso Asynchronous function calls and I/O

o Event-driven

• High performance engineso Chrome V8 is nearly as fast as C++

o The fastest “high-level” language available

• Platforms availableo Johnny-Five Robotics & IoT Platform

o CyclonJS

Nov 19, 2016

JavaScript is not the same

Node.js JavaScript

• Designed for server-sideo No GUI by default

• Async and event-driven

• Variety of protocols (n/o HTTP)

• No built-in sandbox

• Focus on functionality

• Automatic download-install

• Community driven modules

HTML JavaScript

• Designed for client-sideo Generate and control UI

• Control browser (window)

• HTTP (+ HTML5 WebSocket)

• Sandboxed

• Focus on security

• Manual download

• Limited HW supporto Browser specific (GPS, webcam)

Nov 19, 2016

Node.js for IoT

• Strong ecosystem and package managemento 320’000+ packages, Growth 400+/day, npm package manager

o 48% of IoT developers use Node.js

• Programming model suites from embedded to serverso Event-driven model, Asynch functions

o Support for C/C++ libraries (SWIG, node-ffi)

• Completeness of Node.jso End-to-End solution (client-server)

• Supported HWo Tessel 2, Raspberry PI, Intel Edison, Intel Galileo

• Good documentation (Does not apply to modules)

IO.js

• Node.js problemso Lack of active contributors

o Lack of releases

• IO.js is a Node.js fork (2014)o JavaScript platform built on Google V8 engine

o Started by Node.js primary contributors

o Open source

o Compatible with most npm modules

o More active developers than Node.js

o Indefinitely backward compatible

• Merged to Node.js again

• require('tessel')

• require('tessel-av')o https://github.com/tessel/tessel-av

• require('servo-pca9685')o https://github.com/tessel/servo-pca9685

• require('request‘)o https://github.com/request/request

• require('os')o https://nodejs.org/api/os.html

Nov 19, 2016

Making it work

• Install Node.js (v4.4.3 LTS or later) https://tessel.github.io/t2-start/

• Install Tessel CLI

• Plugin Tessel to USB & Boot (30s)

• Verify Tessel connection

• Connect to WiFi

• Run

npm install -g t2-cli

t2 list

t2 wifi –n NetworkName –p password

t2 init

… edit index.js …t2 run index.js
