For MaVo

GroG's picture

 

Hi MaVo, this was an Arduino Uno - I had some problems with subscribing to publishPin, but this worked for my setup.  I just enabled pin 14 which is an analog pin and a stream of values became accessable.

 

You should be able to add or remove from streaming array of PinData with more enables or disables

One step closer to work-e == gert-e

This is a preview of the Emoji service ...  cuz what is better to express the nuances of emotion than emojis ?
Things to fix : (oh god .. the list goes on ...)


Sparse Feature Optical Flow

GroG's picture

I've added "OpticalFlow" filter to OpenCV (worke branch), and here seeing throuhg work-e's kinect eye - you can see worke-e turning left ... or was it right ? :) 

So to make this useful for collision avoidance, some work will need to be put into it.  Like describing the direction vector.  Also some semi-intelligent pruning of data. 

It starts by getting good features to track. Which itself has a few parameters to tweak.

BoofCV - reloaded ...

GroG's picture

Thanks wvantoorn for the link.
It looks like BoofCV is active again ... Woot !

Since there were no updates for a long time I think kwatters and myself lost interest in this project and MRL's corresponding service - http://myrobotlab.org/service/BoofCv

Work-E has grown antenna

Thanks again to Ray's suggestion, I purchased a $9.00 DC-DC buck converter from Amazon - which will be powering all the 12v devices on Work-E such as the wifi router and the kinect ... Progress !


Virtual Joysticks are Un-Breakable ! .. (mostly)

GroG's picture

It took "too" long, but I got virtual Joysticks working ! ...  
To be precise, any device (joysticks, gamepads, keyboards, touchpads, .. etc) which the Joystick service can see can now be "virtualized".

Ok, so what the hell does that mean ? :)
