[Fiware-robotics] Robotics GE live demo - Kurento and Wirecloud

[Luis López Fernández]

Hi Gianmario,

Modifying the Kurento demo for one-to-many to support several robots it's quite trivial. We can do it for you if necessary. This is not an issue.

The main problem I detect is at the WebRTC client embedded in the robot. If this client is Chrome, then you may need human intervention for webcam capture. There are hacks for this, but we need to analyze carefully your requirements. Otherwise, the option is to compile the WebRTC Chrome stack separately and write a C++ application at the robot controlling it. This may require some more relevant efforts and this is the issue we need to discuss.

I'm available during most of this week for discussing. Just propose a slot and we can try to arrange for a call.

Thanks.

> As a short summary, we also have tested a WebRTC client based on Webkit but haven’t yet found the optimal solution, then it would be useful to discuss further this issue.
> The team has done tests with the JS version for the Kurento Client with NodeJS; our idea is to use a single App Server for the master Client and all Viewer clients as in the One-To-Many Kurento tutorial (http://www.kurento.org/docs/current/tutorials/node/tutorial-3-one2many.html ).

> We are also waiting feedback from Wirecloud to understand how we may use or adapt the Kurento widget.

> The guys of the Robotics team will go through your notes to check your proposals and to define technical details if needed.

The only exception is in relation to the WebRTC software to be embedded at the robot. In principle, it seems that you are planning to use directly a Chrome browser instance. This restricts a lot the type of features you may be capable of accessing and this may require human intervention at the robot each time the webcam is activated. I thing it should be worthy to discuss about this specific item so that all of us are in the same page in relation to the consequences of using directly a Chrome instance for that.

> -          The second one (Design of step 1: Teleoperation as a Service (TaaS)) is more or less the same contents of deliverable section 4.4.4
> -          The third part (Detailed description (script) of demo implementation) is the most important one: we took as an example the live demo script doc that Javier distributed through the live demo mailing lists, which seemed to us a helpful way to provide a detailed description of the demo, both for people who will watch it and for implementers of the demo itself.

> We kindly ask Luis, Javier, Alvaro (well all team members…) to go through the description of the demo and provide us a feedback, about how/when this can be implemented (is it meaningful/feasible, etc?), giving possibly answer to the questions/comments we have written there. With your support in linking with Kurento media server and developing specific widgets, we’ll be able to ‘complete the picture’ and proceed straight to the assembly of all demo parts.

>  
> 1)      For what concern Kurento, in our past tests we tried the tutorial http://www.kurento.org/docs/current/tutorials/node/tutorial-3-one2many.html where it is said that it can be present only one WebRTC-Master and many WebRTC-Viewers (i.e. it is created a kind of WebRTC-Room where only one can send the video and the others can receive the video).
> Starting from this point we think the slide2 at the link https://docs.google.com/presentation/d/110H_bSo6QDOgSX9AYxF8fqB7MAoL6Fb_tcnNtIGnBhk/edit#slide=id.p3 depicts the Kurento One2Many architecture.
> Considering what mentioned above, if we want to use two different robots (that act as WebRTC-Masters in order to send video) do we need to use two different Kurento Application Servers (that act as Kurento-Clients) or a single Kurento Application Server (that acts as Kurento-Client) is able to manage multiple robots video transmission?
>  
> 2)      For what concern Wirecloud widgets for Kurento, starting from the slide2 at the linkhttps://docs.google.com/presentation/d/110H_bSo6QDOgSX9AYxF8fqB7MAoL6Fb_tcnNtIGnBhk/edit#slide=id.p3 do the Wirecloud widgets act as Viewer1-UbuntuPC, Viewer2-UbuntuPC, … of the Kurento One2Many architecture explained above in the point1?
> If it is correct, for the Robotics live demo will Wirecloud also host the Kurento Application Servers (i.e. a single one or one for each robot that act as WebRTC-Master in order to send video) within the Wirecloud Application Server as depicted in the slide3 at the link https://docs.google.com/presentation/d/110H_bSo6QDOgSX9AYxF8fqB7MAoL6Fb_tcnNtIGnBhk/edit#slide=id.p3?
