JUnit testing and debugging a service in MyRobotLab

Here's a video tutorial to create a JUnit test to validate that a service is working as expected.  It also shows some simple debugging to set a break point and to step through the code.

 


InMoov , MyRobotLab and Notes on the HS 805BB potentiometer extraction

The below article is a work in progress, it talks a bit about InMoov and MRL at a higher level, but it does have some commentary about reworking the HS 805 BB  servo for continious operation and extracting the potentiometer.

 


Face Recognition with OpenCV in MRL

We're making slow but sure progress with face recognition...


InMoov Nervo Board update

I've been re-wiring my InMoov(s) here with the Nervo board from Gael.  Here's a couple photos that are showing some of the progress.  I've been very happy with how easy they were to assemble, and the make the wiring much cleaner that what I had before.

 


Inverse Kinematics update...

Here's an update on my progress with the InMoov arm Inverse Kinematics.

 

 

 


Wordnet , ProgramAB, and Solr Graph Query

Ok, there's a lot of stuff going on here, so I'll do my best to break it down and provide some background.


Joystick control of the Inverse Kinematics service

Here's a quick demo.  I have added joystick input support to the InverseKinematics service.  It seems to be doing what I want it to..  enjoy!

 


Document connector and processing framework

Connector and Document Processing Pipeline Framework

Document Processing Pipeline Model

 

So, my work work is really around building custom search engines.  I am constantly re-inventing the wheel of creating a framework that can crawl a data source (such as a website , rss feed, file system, database.. etc)


Leap Motion Service and WebGui update

Leap Motion -> Translate / Rotate -> Inverse Kinematics -> publish joint angles -> InMoovArm -> gain + phase shift of angles -> Servo   Woo Hoo ....  End to end functionality.

 

Leap Motion + Inverse Kinematics + WebGUI !

 


LeapMotion hand positon / translation

kwatters's picture

Well.. I started testing the leap motion locally. I found that the leap motion, sitting on my desk can measure a lot of things about the orientation of my hand in front of my body.  It recognizes both left and right hand postion, orientation and finger direction as compared to the palm...

Initially, I am interested in tracking the position of the hand in the frame so I want to start getting a sense of the x,y,z  range reading.  

I see that the x,y,z values range between
