Xmpp gets refactored

GroG's picture

Not checked in yet - but its showing promise ..
Xmpp is very nice in the sense its a protocol which will allow connections over challenging obstacles.
Like NATs  (Network Address Translation) - most people have this on their local network at home (or in the office) where devices are not connected directly to the internet.

But with NAT tranversalling, which Xmpp can do - you can connect one InMoov to another and connect those to phones.


Jython 2.5.2 vs 2.7.0

GroG's picture

Okay, we've been going back and forth on this.
Functionality wise, 2.7.0 has json serialization in it (a good thing) , but something is wonky with some encoding..

I would prefer to use 2.7.0 vs 2.5.2 but I don't know all the encoding issues people have been suffering, or the details.  My own experience is that it's killing my unit tests, which is why we are back to 2.5.2 at the moment.

Does anyone know any details ?  Kwatters said he tried using jvm parameters to fix 2.7.0 encoding.  Do we know what is going wrong ?


WebGui - new functionality

Hi All,

The WebGui has some new functionality.  Its basic positioning, hiding, and showing which can be accessed through the WebGui service.  All functionality of any Service can be accessed through Python.  

First download the myrobotlab.jar from the "latest" link to a new directory.

Xmpp now with Xmpp Server @myrobotlab.org !

This was just a quick test of the new Xmpp server running @ myrobotlab.org.
I tried the service with Google, and they now do not accept connections Booo ! :(
But  I am currently running an Xmpp server which allows the Xmpp MRL service to connect and send/recieve messages.


AudioFile - updates

I thought I do a quick post to describe some of the updates & refactoring I did with AudioFile.

I believe previously most of the Speech Synthesis systems would inaccurately publish events because they did not directly hook into the events of the AudioFile playing of files.


Virtual InMoov in WebGui (a start)

Virtual InMoov currently works in Blender, but wouldn't it be great if we did not need Blender to display ?
Three.js is an great library for using webgl and displaying 3d models and environments.


Things to Come....

DIY Oculus Case

Oculus VR Headset arrived today .. Yay! .. 

  • Suction cups for a phone
  • Open at the end for wired connections
  • Width adjustable eye lenses
  • Focal length adjustable
  • Adjustable head straps

Overall very pleased with design.  The adustable focal length is important because my eyes need very different magnification to focus.

Got NFC stickers too as Alessandro suggested.


Serial Line Speed

We now have lines speed on the serial port.  It will appear and publish the line from a pre-defined sample interval.  The publishing point is Service.publishStats .. the reason I put it in Service is "all" services could potentially use it to measure the speed of MRL's messaging system.  You can only optimize something you can see !   Lots more fixes to do..
