Review previous minutes

Mar-24 minutes

McCool: (go through the minutes)
... Philip's family name "Tran" should be mentioned at the first position

kaz: ok

Lagally: btw, wondering how to handle people's coming in from which entrance and going out from which exit...

McCool: let's talk about that separately

Jennifer: note the requirements for fleet management are complicated

McCool: right
... any problems with the minutes themselves?

Apr-7 minutes

McCool: don't see any problems
... other than Philip's name

<McCool> name "Philip" should be "Philip Tran"

McCool: any objections to publish the both minutes?

(none)

McCool: approved

Agenda for today

McCool: agenda items: use cases, python integration

Lagally: location sensors and people density

<McCool> agenda: use cases (people density, fleet management, connected farms, other), swarm robotics w/ Intel, edgeX/WoT integration update, python-WoT integration

Hazel: some question about possible use cases for Jennifer

Jennifer: you can contact Chinn directly

<McCool> https://github.com/w3c/wot-architecture/blob/master/USE-CASES/smart-agriculture.md

McCool: we're holding discussion on use cases for agriculture as well

Lagally: that use case has specific configuration in Japan

Guest from Intel

McCool: Dibyendu is from Intel Robotics in Singapore

Use cases - revisited

McCool: would like to look at each use case

* use case 1: people density

Jennifer: there is not huge density so far

McCool: need output of people's number?

Jennifer: yes
... the robotics team intends to use AI

<McCool> input is image, uses ai service to identify people, counts them, outputs a number

<McCool> as extension, may measure distance between people

Lagally: analogy of a supermarket

<inserted> scribenick: McCool

Lagally: what happens if density is too high? what is the consequence?

Jennifer: consequence would be an alert (eg via email) to a guard

<kaz> McCool: there is not a uniqueness problem in this use case

<kaz> ... let's pick features from the minutes

Lagally: other sensors like cell phone location?

McCool: specifically bluetooth proximity

Jennifer: problem is, not everyone turns on bluetooth

* use case 2: fleet management

<kaz> scribenick: McCool

McCool: in the future, but...
... (comment from dibyendu: can thermal camera go on a drone?)

Jennifer: dashboard interface to control all robots and view sensors through the entire city in real time
... control meaning you can send commands to robots to move to new locations, drop off or pick up packages, etc
... sensors can include environment, people management (counts, thermal cameras, etc)
... dashboard would include mapping functionality, status of robots and sensors, data visualization, historical comparisons
... which implies location data; also camera and data streaming

* use case 3 - connected farms

McCool: let's defer and discuss in the future...

swarm robotics

McCool: let me send an email to set up a meeting w/ SG robotics team
... summary is Intel Labs in Bangalore have been working on the problem of coordinating multiple ground and air robots, relevant to SG

edgeX/WoT

McCool: demo timeframe is October 2020, at NACS, targetting Retail use cases
... but the work done on the system should also be applicable to Smart City and SG
... collaboration with Conexxus and (probably) Fraunhofer (LinkSmart directory project, eg supporting discovery)

Python integration

Jennifer: any solutions for how to use WoT with python

McCool: could do microservices, perhaps using 0mq for lightweight communication, but I assume you want direct integration

Sebastian: for python integration, are you interested in consumers or producers?

Jennifer: consumer, images

Sebastian: what is the protocol?

Jennifer: http, restful... future, might be video over websockets

Sebastian: main thing is to know what the sensors is offering; need to create and share a wot TD

McCool: summary is don't have full node-wot equivalent in python, but there are a lot of simpler use cases that are straightforward

Jennifer: need to think about websockets and video

Lagally: should we gather requirements first?

Jennifer: people counting uses video, for instance...

McCool: also is a gap in the current health monitoring use case; should document there as well

Jennifer: also interested in C++ integration

Lagally: best to try and capture use case discussions in arch call
