Snake vs. Robosquirrel

Animal behavior scientists are teaming up with engineers to devise new kinds of research tools: mechatronic animal models. Or you could just call them robots. Robosquirrel Is that a real squirrel? Nope! Chuck Testa. That was a joke…Chuck Testa was not involved with this study. But given his talents, maybe he should be involved with ethology research robots. Now you may [...]

Motor Mount


Simple friction based mount for copal motors (used here on 30's will also fit 60's) ... currently i don't see the need for a top piece to hold the motor in place, it's wedged in there pretty good, but there is room to mount a top plate in the future if needed.

designed in sketchup and printed with my Thing-o-Matic Makerbot.

Artificial Intelligence in Russian

Fri.3.FEB.2012 -- Recognizing Inflections

For the Russian-thinking Dushka AI Mind, we have perhaps stumbled upon a way to avoid the hard-coding of noun paradigms and instead to let the Russian AI learn the inflected endings of Russian nouns from its own experience. For example, right now the Russian artificial intelligence (RuAi) fails to recognize the Psi concept #501 БОГ in the following exchange.

Human: я уважаю бога ("I honor God.")
Robot: ТЫ УВАЖАЕШЬ БОГА ("You honor God.")

Robot: ЧТО БОГА ТАКОЕ ("What is God?")

The diagnostic display reveals that the software has almost recognized the word for God.

559. Б 0 * 1 1 0
560. О 0 * 0 1 0
561. Г 0 * 0 1 501
562. А 0 * 0 0 902
Aha! Suddenly it becomes clear that two things are happening. The Psi concept #501 is indeed being recognized at first, but perhaps the provisional-recognition "prc" variable is not being set, and so AudInput calls NewConcept as if the AI were learning a new word instead of recognizing an old word.

Sat.4.FEB.2012 -- Learning Russian Like a Human Child

Now in a very rough way we have trapped for "zad1" in the AudRecog module so as to recognize a noun (БОГА ) with one character of inflection added onto it. Because the noun was indeed recognized, the InStantiate "seqneed" mechanism tagged the noun in the "ruLexicon" with a "dba" of "4" to indicate a direct-object accusative case. In other words, the Russian AI learned a new noun-form as a human child would learn it, that is, from the speech patterns of another speaker of Russian.

9 Jan 2012 The Swirling Brain   » (Master)

Last year for the Swirling Brain (2011):

I constructed a Raspberry Pi case on Shapeways. I keep thinking I'm finished but it seems like I keep having to adjust things or it gets rejected so I have to revise something. I hope to have it for sale soon. I decided to make this case after writing the Raspberry PI article for robots.net. It sounds like it will be a very popular board and I hope to use it for a robot perhaps.

My daughter Bethany went into the hospital a couple of times because of her CF. We got to spend Christmas in the hospital. We planned to have a vacation the week after Christmas, maybe even go to Disney World (that's more of a dream than reality) but I'm glad we hadn't committed since all of the plans were out the door when we got the news. Her CF hospital visits are increasing the older she gets. Her PFTs (pulmonary function test) were down to 32% which is super low. She got them to 52% and they let her out of the hospital. That's still pretty low and it's hard for her to breath anymore. They put her on 3 IV home antibiotics that she had to administer through her two picc lines. Now she's back on aerosol tobramycin (tobi). She doing better and she went back to work but she's still not doing that great. Pray for her.

I'm on the media team at First Baptist Garland. I've been running the sound board for the teens on Wednesday nights and helping with setup on Sunday Mornings. I've actually got to run the big board in the Sanctuary but just for band practice and not for a real live Sunday yet. It's sort of a big deal at a big church but perhaps someday.

My white car the Buick Rivera finally bit the dust. I was without a car for a while and my wife had to take me to work. We couldn't afford another car so I kept hounding my wife for a motorcycle or a scooter. She finally caved and let me buy a scooter. I got one off of craigslist. It's a chinese scooter so the odometer is apparently in kilometers so I have to convert to miles. I seem to get about 72 to 80 mpg! At the current gas price of about $3.50 a gallon that's about 5 cents a mile. It's about 7 miles to work so the cost to drive to work is about 70 cents a day. My dad let me borrow his truck for cold or bad weather days and it gets about 18 mpg which is about 19 cents a mile or about $2.72 a day. So I save about $2 a day or I save about $10 to $15 a week driving the scooter to work and church and other misc places. Just in gas that's a savings of about $500 to $700 a year. Everything else such as fees, insurance and taxes also seems to be cheaper for a scooter. Insurance was like $70 a year. I'm driving lesser driven streets to try to be safe.

I played with jpct (www.jpct.net) and wrote a 3d speedometer android app. It is pretty cool. I wrote some other cool things with jpct too. So then someone broke into our house, stole my laptop, stole my xbox 360 and kinect and stole a dvd player and some money we had at the house. They stole a few other items also. My biggest loss I still feel was the various software I had written on that laptop that I didn't have backed up anywhere else. I think I found an old backup of some of it but still it's a loss. So I've been down about that. Since then I've bought some IP cameras and installed them around the outside of my house. I feel like a theif may get away with it again but at least I might get a picture of them that I could give to the police.

I made some more rolling ball sculptures and sold them on ebay. Besides that I video recorded the building of some of them and listed them on youtube. Google invited me to be a part of their adsense and I agreed and wow I'm getting about $50 a month from that! That's like free money for doing practically nothing. I can now see why there are so many stupid videos of people making a complete fool of themselves because they are laughing all the way to the bank! Click on my videos and help me make some money! ;-)

I'm sure I did more in 2011 but that's all I can think of right now.

It’s 2012, Time to Talk Resolutions?

Another year gone and it’s time to take stock of things done and make some plans for the new year. Do you want me list off a lot of goals and resolutions for 2012? I didn’t think so – too boring. How about if pull out my list of goals for 2011 and tell you some of the stuff I actually did. Things really done are always more interesting to read about.

After devoting a huge amount of 2010 to getting Dallas Makerspace off the ground, I took most of 2011 off from hackerspace managing. I attended meetings and helped out now and then but most of my time and interest went elsewhere.

In late January 2011, I joined a team of Camerpedia editors in saving the website from being assimilated by Wikia. We relaunched it under the new name Camera-Wiki.org. I developed quite an interest in Vivitar history and have been collecting many of the oldest Vivitar lenses; not just to document on Camera-Wiki but also to shoot with. Camera-wiki.org has been a huge success and has attracted lots of new editors. It’s growing at a faster rate than it ever did in it’s previous incarnation and we’re working hard to improve the quality as well as the quantity of the content. Hosting is paid for entirely through donation, so if you appreciate old cameras and lenses, why not help us out by donating a few dollars to our hosting fund!

I’ve continued to pursue photography in other ways. I did several more shoots with models in 2011. I did several paid shoots including a gig as the official photographer for the 2011 Vex World Championships. My photo essays continue to be published in Robot Magazine and Servo Magazine. One of my photographs was displayed in a local art exhibit, meeting another of my goals for the 2011. I hope to be in more exhibits during 2012.

Susan and I attended lots of art exhibits, music performances, and a few lectures. I managed to get to several Pecha Kucha and Spark Club events. Much more of the same for the 2012 I hope!

If you’re not an Advogato or robots.net user, you won’t really care but I finally managed to get the long-awaited libxml2 parser into the mod_virgule code base. It’s still a bit buggy but no more so than the old parser and it provides a good path forward for consolidating and simplifying the code. Whether mod_virgule can remain relevant in the world of Facebook and Google+ is another question. Perhaps 2012 will provide the answer to that one.

2011 was the year I finally created some ornaments for the annual Blue Yule charity auction at the MAC. I also volunteered at the 2011 Art Conspiracy Auction. That took care of two more 2011 goals. I hope to find a few more outlets for my artistic and creative sides in 2012.

As usual, there were goals I didn’t meet in 2011. I didn’t finish the project of scanning all my family photos. This has turned out to be much more material than I’d anticipated. I’ve scanned thousands of old photographs and negatives so far. Hopefully 2012 will see the scanning portion of the project completed.

2012 is an election year but with Obama running for his second term that means there is only going to be a Republican primary this year. I consider myself an independent but still feel compelled to vote in the primaries, which means this year I’ll be voting in the Republican primary regardless of how I vote in the final election.

At present I’m leaning toward Ron Paul for the primary vote. I don’t really like any of the choices but Ron Paul seems the least insane of the bunch and I think may be the only one of them who holds any positions at all that I actually agree with.

So for the next four years, the State of Texas will consider me a Republican despite my claim to be an independent. I’m pondering whether I should start going to my local Republican group meetings and see if I can do anything to reform them or shift them a bit toward the center or at least slow their movement toward the right-wing fringes. Unfortunately, I don’t think reason mixes well with the far right (or the far left for that matter). I’ll report on my experiences if anything interesting happens.

The issue here is a conflict between the old/new upstart for Debian on OpenVZ pl
atforms, the VPS was hanging on the init phase, causing the main initialization
scripts not to run which includes the network and sshd for SSH access. I had to
manually create a pty (pseudo terminal) through the node, enter your VPS and edi

instead of what was previously set (which is now commented out with #, one line

I pledge my support to Software Freedom Conservancy. Their current Member Projects. I hope to work towards implementing Raph's Trust Metrics to build democratic process for Chinese ordinary internet users using Darcs as my distribution platform.

I believe co-operation is a learned world view. To build Trust is a difficult task among different people sharing little common senses as pockets of world material/natural resources are controlled even more tightly than ever before. Cooperative activities are never to be taken for granted. Our natural instinct is to defend ourselves against extinction, suppression, enslavement on every turn. So help me folks. Thank you.

Congratulation, Mrs. Tai, for translating Dr. Lee's autobiography 'Making a World of Difference' from English to Chinese. I am looking forward to reading your 中華文化詩詞入門. I also would like to read works by Dr. Lee's late father and Chinese historian 李天民 .

I am also most interested in two different versions of history books about Chinese Civil War (1927-1949/1950) .

According to wiki, "However there is debate on whether the war has officially ended. The conflict continues in the form of military threats and political and economic pressure, particularly over the political status of Taiwan. The continued tension is described in cross-Strait relations." 2007年中共十七大時,中共中央總書記胡锦涛提出「兩岸簽署和平協議」主張,当时執政民主進步黨并沒有正式回應。但在國民黨二次政黨輪替後,總統馬英九称不排除與中國大陸簽署和平協議,不過並沒有時間表

在冷戰漸趨緩和之下,中華民國自1980年代後期起實施一連串的民主化改革,並恢復與中國大陸的交流,國家體制遂漸與台灣社會相融合。現今的中華民國於國際間常因地理位置或政治因素而通稱為「台灣」或「中華台北」,以經濟成就與民主改革聞名於世[2][3]。

轟動一時的國際事件江南案
Henry Liu (7 December 1932 – 15 October 1984), often known by his pen name Chiang Nan (江南), was a writer and journalist from Taiwan, Republic of China. Born in Jingjiang, Jiangsu, China, he was a vocal critic of the Kuomintang (Nationalist Party), then the single ruling party of the Republic of China in Taiwan, and was most famous for writing an unauthorized biography of Chiang Ching-kuo, former president of the Republic of China.[1] He later became a naturalized citizen of the United States, and resided in Daly City, California, where he was assassinated by the Taiwanese.

Projects Galore

Allo,

I’ve been working on several projects since my last real post. It’s overdue for an update, and it has certainly been interesting.  I had setup a CVS Server, to house my software projects. However, since I’ve been using SVN at work, and that has been the evolution from CVS, or maybe GitHub.  So I have been setting up a remote SVN Server for my robotics and other project codes. The server has been setting up, but been playing around with hardening the Server (ie. Firewall, etc.).  I’m still playing around with the settings, and testing, but I’m almost there, and will be fully functional real soon.

I have been experimenting with the GPS Module I have acquired, and the sensors for Max (ie. Ultrasonic/IR).  It has been fun.  I’ve also been experimenting with the Odometry sensors, on a test jig, and tuning the ccts.  Some other experiments are with Linux, and Android as they may apply to Robotics.

I have also created a couple of Arduino boards, and playing around with how small I can build it. If I have some sort of SMD or QFN Package, that would be cool. It’s fun, and more like a challenge, but…been there, done that. So maybe I’ll create a PCB prototype, or just modify my prototype AVR board to accommodate the Arduino design. You can check my latest prototypes in the HERE.

The Sun Bots Site is being redesigned, and will also have more updated pictures and info, pertaining to the latest, of the latest…There are a few features in mind, and some new directions I want to take the group/club, but we’ll see…

At The Learned Nerd (TLN) Makerspace, we are looking into working on some other projects, including Guitar Amp, Arduino projects, Odometry, Metal Detectors, and lots more.

Sensor Fusion, Machine Learning, Algorithms, AI, Robotics for several new applications, etc…There are lots more in the works, but that’s all for now. I will update again soon…ABCYA!  Hope you’ll come back soon…y’here?

NAO robot from Aldebaran Robotics enters now the age of social machines. A small company, Generation Robots has created its first complete behavior for NAO. This behavior is intended to be the first of a complete line of behaviors to ease the adoption of companion robot at home.

The following web page describes the behavior and the algorithms used by the R&D team of Generation Robots called HumaRobotics.

In this behavior, NAO plays Connect4 against a human partner. The focus has been put both on the game play and the robot-human interaction. Indeed, to be accepted as a social companion, NAO has to interact with human by localizing and recognizing him using voice and facial recognition. To emphasis on this social aspect, the robot has been given an “emotion engine” (in beta version for the moment) so that, given its performance in the game and the nature of the interaction with the human partner, NAO changes its mood and can act differently.
The Humarobotics team plan to make this behavior more precise and more robust. The emotion engine and the attitudes of NAO during the game will also be improved. The team is waiting for suggestions and comments, so don’t hesitate to go and see the behavior.
