DHB-10 Dual H-Bridge Motor Control

The DHB-10 is a thing of beauty!

Finally cracked under the great emotional strain of the new Arlo Complete Robot System release and ordered the DHB-10 Dual H-Bridge. It is back ordered right now - which should give me time to study the pdf product info...

My Arlo-like version is a bit Frankenstein-ish going back to the original 12 V Wheel and Motors, MadeUSA, Eddie, etc. - even have one HDPE platform and one plywood platform! ;-)

With the new DHB-10 - I should be able to play with new stuff up on Learn.parallax.com and use my Propeller Activity Board along with the new motor controller for some "up-to-date" fun without the nifty wooden box, of course, - maybe erco can send me some scrap plywood...

Fly by Night

The performance, created by artist Duke Riley, is called “Fly by Night.” It is presented by Creative Time and the Brooklyn Navy Yard.
“At the call of a whistle, thousands of birds will emerge from their home in a grand, converted historic boat docked at the Brooklyn Navy Yard,” the description for the exhibition explained. “The pigeons will circle above the river as the sun sets over Manhattan, and small leg bands, historically used to carry messages, will be replaced with tiny LED lights, illuminating the sky in a transcendent union of public art and nature.” Story from CBS New York - here.

Louisiana Tech Robotics Competition 2016



Louisiana Tech held its annual Robotics Competition (and demonstration) yesterday, May 6, 2016 in the "Tonk" or student center. The event was organized by Tech's Computer Science Department and sponsored by Pioneer Rx Pharmacy Software, and Praeses - two software development companies out of Shreveport. Both companies had representatives there.

The event was well attended and featured a maze competition, design competition (which was more like a demonstration of various design ideas - Social Media App Controlled Bot, Voice Controlled Bot, a Spiro-graphic Scribbler, Floor Sweeper, Card Dealing Bot, Nerf Gun - with targeting and tracking, Painting Bot, Package Sorting Bot, and several more!) followed by some further demos of hobby projects, and robotic toys and gizmos.

One of the graduating students had a Parallax ELEV-8, V3 - quad-copter - modified with obstacle avoiding sensors and successfully demonstrated his proof-of-concept.

The thing that impressed me most was the enthusiasm, and the diversity of the crowd in terms of age, gender, and ethnicity - it was a true cross section of the university and community at large. I would say over a dozen elementary aged children attended and were very excited and actively engaged. Students also clearly had non-technical friends attend the event to cheer them on!

There were many failures and partially completed projects - just shows that in robotics - real-life implementation is often a trial and error process of failure, revision and refinement. Roboticists are always - Back to the Drawing Board, Computer or Lab Workbench!

Special thanks to Ben Choi, Ph.D., Computer Science Department, for organizing this event and to Jean Gourd, Ph.D., Program Chair of Computer Science, for showing up to cheer folks on!

Star Wars Fun-bots.

R.U.R.



According to Wikepedia, here:
R.U.R. is a 1920 science fiction play by the Czech writer Karel ČapekR.U.R. stands for Rossumovi Univerzální Roboti (Rossum’s Universal Robots).[1] However, the English phrase Rossum’s Universal Robots had been used as the subtitle in the Czech original.[2] It premiered on 25 January 1921 and introduced the word "robot" to the English language and to science fiction as a whole.[3]
I've posted here many times about R.U.R. and it's influence on Robotics Under the Stole, especially the RUS favicon. Above are photos of the Cover and Title Page of R.U.R. and below is the RUS favicon.



Boilerplate


A little known piece of robotics history* is the story of Boilerplate.  A wonderful website about Boilerplate maintained  here and a book about this history is available at Amazon here.



* Just in case you were wondering - see this from Gatehouse Gazett.
