DigitalTwins (DRAFT)

TUTORIAL:

USAGE:

SIMULATE:

The webthing is served and can be queried using http client

git clone https://github.com/rzr/twins ; cd twins
make start

url=http://localhost:8888

curl ${url}/properties
#| {"torso":0,"shoulder":0,"arm":0,"hand":0}

curl -X PUT -d '{ "arm": 42 }' $url/properties/arm
#| {"arm":42}

VR view can be used alternatively:

cd twins/aframe
npm install
PORT=8088 npm start

http://localhost:8088/

Some params can be added to configure app:

http://localhost:8088/?useWs=yes&verbose=yes

Next the device can be connected to mozilla-iot Gateway

PHYSICAL:

STM32F7 based MCU is running webthing-iotjs with IoTjs for NuttX (until TizenRT is supporting this board).

http://rzr.github.io/twins/aframe/?url=http://webthing-host:8888# (on HTTP)

More details soon:

For instance target

http://rzr.github.io/twins/aframe/?url=http://192.100.0.243:8888

url=http://192.100.0.243:8888
curl -X PUT -d '{ "arm": 42 }' $url/properties/arm
curl -X PUT -d '{ "arm": -42 }' $url/properties/arm

GATEWAY / Remote Access:

Once connected to mozilla gateway it can be controlled from the Web UI, or curl commands using JWT issued from security menu.

VR view can be used alternatively:

cd twins/aframe
npm install
PORT=8088 npm start

Websockets can be also used:

Some settings should be set:

wsUrl:
wss://sosg.mozilla-iot.org/things/http---192.100.0.13-8888-

http://purl.org/rzr/tmp/example Then config will stay in localstorage so direct link will work:
http://rzr.github.io/twins/aframe
http://rzr.github.io/twins/aframe?verbose=yes

CLOUD:

For development purposes app can run in cloud.

url=https://twins.glitch.me
curl -X PUT -d '{ "arm": 42 }' $url/properties/arm

Then twin can be visualized using:

http://rzr.github.io/twins/aframe/?url=http://localhost:8888

DEVEL:

I think this one is a good entry door, tell me if you’re able to replicate:

https://github.com/rzr/aframe-smart-home

Once you have replicated the earlier example, this one is good about XR binding:

https://github.com/rzr/aframe-webthing

Last one about the REST API to define abstract things and deal with I/O (sensors etc):

https://github.com/rzr/webthing-iotjs

For your curiosity other related subprojects, once you’re comfortable with ones I just mentioned above.

Good luck
