Participating in EU Robotics Week!

November 28th, 2011

EU Robotics Week !

GuarddoG ( and me ;P ) will be participating in the EU Robotics Week with an event at the Athens Univeristy of Economics and Business in the D21 room 15:00-19:00 in 2 December 2011 .

There will be 3 projects presented there ( guarddog is one of them ) and everybody is welcome .. ! :)

European Robotics Week: 28th of November – 4th of December 2011

Over 350 robotics related events throughout Europe with more than 130 participating organisations from 19 European countries

The European Robotics Week offers one week of various robotics related activities across Europe for the general public, highlighting growing importance of robotics in a wide variety of application areas. The Week aims at inspiring technology education in students of all ages to pursue careers in STEM-related fields, i.e. science, technology, engineering and math.

There is a lot going on in Europe during the European Robotics Week: school visits with lectures on robotics, guided tours for pupils, open labs, exhibitions, challenges, robots in action on public squares…. The participating companies, universities and research centres have come up with interesting programs to bring their robots and organisations to the attention of the public educating them on how robotics impacts society, both now and in the future.

The idea received overwhelming support of the European robotics community as the amount of events show. Throughout Europe, more than 130 research institutes, robot manufacturers, universities organise events reaching out to the general public within this week.

It’s time to show the general public what robotics is all about and what important role robots already play in Europe!

Events are organised locally (by scientists, labs, teachers, schools, robotics engineers, robot makers etc.), but centrally listed and co-promoted. The euRobotics Coordination Action (in particular EUnited Robotics) is acting as the central coordinator. They are supported through national coordinators who are promoting the idea among their national networks and communities.

Skipping frames to improve cpu usage / power consumption

Frame Skipping when no movement improves cpu usage for guarddog

Frame Skipping when no movement improves cpu usage for guarddog

I Just added a frame processing skipper for when there are no changes on the frames (after a very quick check implemented here ) and therefore computation of faces , corners , RANSAC tracking and depth mapping has no meaning ( because the image remains almost 99% the same )
I will have to add some cooldowns ( i.e. 1 mandatory recalculation after 2000 milliseconds of skipping )

In the graph you can visually see when the skipping occurs and when normal processing takes place.. :P

This Behaviour is switched with VisCortx_SetSetting(USE_MOVEMENT_FLOW_FOR_CALCULATION_SKIPPING,1 or 0 :P )

Linux Inside Magazine Interview : )

Linux Inside Interview AmmarkoV GuarddoG

An interview about GuarddoG has just been published in the Greek magazine Linux Inside , issue 6 , the interview doesn’t get into much detail , but it is very nice to see my work in one of the few Greek magazines I read :D

Adding Performance Statistics to GuarddoG

November 21st, 2011

As I begin to fully document the GuarddoG Project ( a git updated draft under heavy development can be found here ) I also have to document and compare performance results so that they can give a clearer image of what it does and be used in context with other algorithms and projects. :)

GnuPlot is an absolutely fantastic tool for this job and with it GuarddoG can now produce ( by itself ;P ) plots of its performance that are automatically converted to images and auto updated on git :)

Fixed some cabling issues

November 14th, 2011

I just fixed ( it was about time ) some cabling issues , and temporarily removed the breadboard that does the battery/transformer/charger switching that prevented guarddog from booting successfully at its public appearance in AUEB today

Finally a proper lasercut plexiglass stereo rig !

PS3 Eye Stereoscopic rig plexiglass laser cut

PS3 Eye Stereoscopic rig disparity mapping software

As the final body of guarddog is beginning to take shape I got the new guarddog “eyebrow” that is the mounting point for the two PS3 eye cameras ..

As said in an older post the “schematics” for the laser holes are theese , with all the distances beeing distances between the center of each hole.


Once again thank you Antonis :)
