Robot Memories...

kwatters's picture

So the general question is:

What should your robot remember?  What should your robot recall?  How do you want to access their memories?

More details to follow...

 

Teaser:  We will embed a "core" to store robot memories.  I think these memories probably include things like.

1. what did I hear?

2. what did I say?

3. what did I see?

4. what did I feel/taste?

5. what did I smell?

 

We can establish a common storage format for all of this and it can be shared!


The uncanny Mr. Turing and his deep learning of with LSTM neural networks

I recently attended some training classes around a deep learning framework called Deeplearning4j.  It was provided by the company SkyMind.IO, they're the ones that created, maintain, and support the dl4j open source project.

So, sometimes an arduino running mrlcomm will get away from you.  The best way to reset it is to toggle the serial port.  This resets the arduino that's connected and thus clearing the device list in mrlcomm.

Here's a small snippet of python code that will toggle the DTR pin and reset the arduino.

Campaign for MyRobotLab on Wikipedia

Update: This document now open for anyone to edit...  

https://docs.google.com/document/d/1HDlE8d--x1-A56Ff5mcQehE5togKtGt4yuuGIHVStgk/edit?usp=sharing  

 

so.. I see that there are 2 pages that point to MyRobotLab on wikipedia.

1.  the InMoov page : https://en.wikipedia.org/wiki/InMoov

2. the open source robotics page : https://en.wikipedia.org/wiki/Open-source_robotics

 


Raspberry PI + OpenCV on latest

So, it seems like the upgrade of OpenCV to version 1.3 has busted the OpenCVFrameGrabber on the RasPI3.  Where, I don't have a fix for this issue yet, I do have a work around for the problem.  Here's the steps to get OpenCV working on the RasPI3 on the latest build  (until we sort the javacv 1.3 issue.)


Deeplearning4j , OpenCV and real time object recognition

So...  it works! sweet! Here's the proof!

 

 


The road to deep learning for MRL.

So  One of my new years resolutions was to add some deep learning support in MyRobotLab.  Reality is, this is a big topic and covers many aspects, but at the end of the day I boil it down to this.


ProgramAB and InMoov

----- 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.)


Mycroft AI Mimic Speech

as of build 1891...

There's a new speech service.. MimicSpeech.  MimicSpeech is a wrapper around the "mimic" speech project from the Mycroft AI project.

At a friends birthday party recently someone said I should look into the Mycroft AI project.   So, I did, it looks like they've done a good job running with much of the CMU speech stuff.  


DIY Servo Service

Update:  https://github.com/kwatters/DIYServo OpenSCAD and STL files have been posted to github for those who want to try it out!

It's worky!  Testing out Mats new DIY Servo service.  This uses a 3D set of printed gears, a 12V DC motor, an LN298N dual hbridge motor controller and a 10k ohm linear trim rotary potentiometer.  Woohoo,  the power of PID controls you!  The power of PID controls you!
