Domotic Dojo!Why me?What is domotic?What is home automation?What are the current platform?What are the current trends?How does Robomotic see the future?

An overview

Robots are taking over

Yes they are taking overRoomba sold 940,000 vacuum in 2008, not too bad for a young market

But wait!

Rodney Brooks lost his way?

Left in 2009 the role of CTO to found

Heartland robotics For human-robot

And now we got this?

A camera with wheels?

Home automation

It is the use of computerized systems or components to control devices and/or processes, in a hose or building, so that the user of the compound can satisfy their needs in a more simple, quick and effective way, than without automation.

Domotic

Introduced in 1984 by Bruno De Latour Several meanings:

Domus + Informatics Domestic robotics

It is ubiquitous home automation with built in intelligence

A typical architecture follows

Domotic Architecture

RF wired orWireless network

StuffApp Layer: SimplicityRF layer: Zigbee etc.

Gateway Internet

PachubeInternet of Things

FHEMHouseAgent

HomeNet

RF layer

RF layer: carrier frequency and modulation Example: 433 Mhz, ASK modulation IEEE standard allocates RF bands for home

and recreational use: Sub Ghz band:300-348 MHz, 387-464 MHz and

779-928 MHz 2.4 Ghz band: Zigbee

What is better in the indoor environment?

I love japan!

Data Rate and Range

Security

Private and public encryption could be implemented virtually on every RF layer but..

Lower frequency= lower data rate Most cheap producers don’t bother Common RF protocols are vulnerable to reply

attacks. High end RF modules provides dedicated

hardware like AES block etc.

Security examples

TI CC2520: 128 bit AES Xbee: 129 bit AES hardware and

asymmetric encryption PanStamp implements NONCE with the

CC1101 Jeenode uses a simple MD5 symmetric

ZigBee ISO standard 2003:  IEEE 802.15.4 ISO manufacturers:

Ember: certified original firmware stack Amber wireless: Zigbee. Sub Ghz, Bluetooth Texas Instruments: Zigbee. Sub Ghz, Bluetooth DigiMark from Zigbee Standard Freaklabs: open source firmware stack!

Home automation

Domotic

HomeMatic: Web interface iPhone, iPad interface

HomeEasy: Web interface SMS interface

Domotic

Alert Me: Web interface iPhone interface

And now the bad news...

Although we kind of managed to choose a common RF protocol

A proliferation of application protocols: FS20, FHT, HMS, OneWire, X10, S300, EM,

HomeMatic, KNX

A first attempt: KNX

KNX is the only global standard for home and building control with A single, manufacturer independent design and

commissioning tool (ETS). A complete set of supported 

communication media (TP, PL, RF and IP). A complete set of supported 

configuration modes (system and easy mode).

Why is not widely adopted? Don’t ask me!

Zwave an example

How closed and open source coexists

Zwave is proprietary BUT some vendors opened and now there’s Open ZWave

What about the open community?

Open hardware: Sensor network like Jeenode, Panstamp, Norduino Plug computers: Chumby Hacker Board, Open Picus,

TuxGraphics Board

Open software: Gateways: HomeNet, HouseAgent, FHEM Utils ... Protocols: PANSTAMP Cloud computing: Pachube, ThingSpeak

Sensor networks

Anatomy of a gateway

FHEM:  GPL'd perl server for house automation Supports many protocols except OpenZWave RF interface: CUL busware
