BoardInfo Bug

GroG's picture

Sorry,
I created this one :P

As Calamity pointed out there is some missing runtime type identification of the board, which I recently  commented out. (I owe a unit test ! :P)

Now some history on it :

MRL can now "potentially" compile and upload the board, its necessary to send the correct command line parameters to avrdude.  This is "sort of" done in the ArduinoUtils - but it does not have all the needed types for all the boards.


Advice appreciated with a couple of issues - Windows and Mac OSX

I would appreciate anyone's thoughts on these issues:

I'm using a USB Hub which is working okay. The same one Gael recommended. 


Plantoid Deep Dive Research

Lately I've been able to pick up on Plantoid research, its been great to be able to stretch out in a new shop space and unpack the 'bots, which are in great need of repair and upgrade. 

So far, updates to latest MRL and services seem to be going well, though many services still aren't starting, I haven't been able to keep testing for bugs, as lots of areas need some direct attention there. 


Tutorials

ShaunHolt's picture

Video or picture tutorials? Which do you find more useful?

Starting with a complete 3d printed Inmoov, this is what I am starting with for a series of tutorials.

Giving the robot vision, a voice, hearing, and personality.

Connecting 2 raspberry pi's to work together, also two instances of MRL communicating with each other.

OpenCV running on one.

Program A/B and MaryTTS running on the other.

 

My intention is to make these as simple to follow and understand as possible, with newcomers in mind.


Kinect One with MRL under windows

Bretzel_59's picture

OK guys,

 

This is how to use kinect one with Open NI under windows :

just download this driver : 

https://github.com/kaorun55/OpenNI2-Kinect2Driver/blob/master/Bin/OpenNI...

and copy it under this directory : root:\MRL\libraries\native\OpenNI2\Drivers\

 

Launch the Open NI service :


ProgramAB and InMoov

kwatters's picture

----- UPDATE 2017/05/16 ----

InMoov and ProgramAB can be modeled a bit like a human.  Let's  think of it in terms of the parts.

  • Ear
  • Brain
  • Filter
  • Mouth

Ok,  above we have an ear, an ear recognizes text and publishes that to the brain.  The brain takes that text and produces 2 things. 1. a responses as text and 2. out of band messages ( generic mrl messages , we'll talk about these in other posts.)


My 3D printed omni-directional mechanum wheels for Ghost the inMoov

I've made 4 of these, from ABS, with the Flashforge 3D printer and hope to make them work on my inmoov, 'Ghost'.  


More cool stuff from Festo

Very cool stuff from Festo ..  First time I heard them say ROS (what?) :)

 

 

Simple compressions joints ... very cool


Help ! strange things again about servo moves

moz4r's picture

Before to call an exorcist I will ask you :

I have sometime problems about no worky commands ( rest() moveTo() or autodetach if velocity =-1 )
Problems ocure often at startup.

This is the smallest thing I can use to isolate. When I launch rest() , slider in swing go to the asked position, but no action on servo or virtual servo. ( like the servo is disabled, but servo is electrised)
and if I move the slider a little degree, servo go to good position.
