Old and New side by side

Here is some general crazyness ... 

This is using 2 completely different GUI systems at the same time.   Since MRL IS NOT THE GUI !  It works quite well :)

2 MRL Instances on 2 different machines have combined and give access to all of the services running on both machines.  2 Views of distributed computing !

The layout is as follows:

Laptop - running runtime (borg)


Shape of things to come ....

Simplicity Is Beauty

And the following I think is very simple

http://somehost/services/myThingy/someMethod/parameter0/parameter1/..../parameterN

Unfortunately - this breaks down when there is a "/" in the parameter :(
An example of this would be 

http://localhost/services/arduino/setSerialDevice//dev/ttyUSB0

instead of this being equivalent to 

arduino.setSerialDevice("/dev/ttyUSB0")

it becomes


We are One !

This is our two instances joined together.  One is mine which has grey tabs - gui, runtime.  And the other tabs are from your system. python, raspi, remote.  I can now start any service on your system from my system - including executing scripts.  The "bad news" is OpenCV is not behaving nice (as usual) .. so no video at the moment ..


A Rare Sight Indeed !

Thanks Gael !

I'm getting all emotional ... because, how often does this happen ?   :D D D


MRL's Dynamically Generated WSDL

GroG's picture

A WSDL is a interface defintion.  It's like a contract, that is written in XML.  What is good for? I'm glad you asked :)


Multi-Parameter Subscriptions

Update

To more easily understand - this is how MRL currently does subscribptions

A possible enhancement would allow references or static values to be mapped into the subscription / publication route.

Like this :


Servo I2C Progress

Small but relevant success.  I managed to connect all  the pieces together and get the Adafruit 16 channel Servo test to work with 1 servo.  Now to borg it into MRL :)
