Build Your Own DARwIn-OP, the Open-Source Humanoid Robot

DARwIn-OP RoMeLa

Meet DARwIn-OP, America's newest humanoid robot, unveiled this week at IEEE's Humanoids 2010 conference. He is 18 inches tall, weighs 6 pounds and is ready to be messed with. It's OK, he's an open-source bot.

Designed by Dennis Hong's RoMeLa team at Virginia Tech with collaborators at University of Pennsylvania's Grasp Lab, Purdue University, and Korean company Robotis, DARwIn-OP's hardware and software are open-source - you can fabricate the parts, choose your own electronics and build one of your own. And why wouldn't you? There's something so cute about his Astroboy fins.

In the video below, he claps his hands as Hong provides a somewhat breathless introduction, and is undaunted when Hong kicks him over. He kicks a red ball and falls on his face when Hong removes it.

About 10 DARwIn-OP units were making the rounds at IEEE this week, and afterward will be distributed to the partner universities. If you don't work in a robotics lab and don't have access to a CAD system, Robotis will build one for you, to the tune of $12,000 ($9,600 with an educational discount).

He even plays soccer. Sounds like a bargain.

What Do You Do with Posts When You Change Your Opinion?

A few days ago, personal development blogger Alex Shalman sent me a question that I thought might be a good discussion starter. He asked: I feel like after many years of blogging that my opinions have changed. That’s natural, and in most cases it’s okay to have that archive of articles as a track record. [...]

Dark Helmet's Favorite Techdirt Posts Of The Week...

We're going to try something new for a bit to see how it works. Lots of blogs put up weekly summaries of the posts they want to promote the most, and we've considered doing something like that as well. However, after thinking about it, we decided it might be more fun to have a member of the wider Techdirt community pick his or her favorite posts each week with a short explanation of why they liked those posts. Each week we'll ask a different community member. To kick it off, who better than champion commenter Dark Helmet (aka Tim Geigner), who provided the following....

Wow, what a week.  Mike has planned a pretty cool little weekly feature, asking a different regular Techdirt reader to highlight their favorite posts of the week, and he asked me to give it a go this week.  Obviously Wikileaks has been the dominant topic, but there was plenty else going on as well.  I'll list my top five favorite stories below:

1. If Assange Were In China, US Politicians Would Be Cheering Him On: If there's anything that drives me completely up the wall, it's hypocrisy.  This instance is particularly transparent, especially if we keep in mind all the heralding our politicians were doing over Twitter's role in providing insight into Iran's elections and subsequent rioting.  It's just never as funny when it happens to you, is it?

2. So Wikileaks Is Evil For Releasing Document...But Dyncorp Gets A Pass For Pimping Young Boys To Afghan Cops: I've made no secret that I think too much transparency is better than too much being hidden with our government.  Stories like this show why.  Two things spotlighted by this story: I don't think that people realize how many private contractors make up our fighting forces and how detrimental those groups tend to be in our supposed efforts to win over the hearts and minds of belligerent nations.

3. NIH Won't Let Others Supply Life Saving Drug Even Though Genzyme Can't Make Enough: It feels odd to say that I like a story that involves people truly suffering, but examples like this are how you can get people interested in some of the real issues surrounding intellectual property.  It's one thing to trot out examples of multi-million dollar corporations bickering with each other over patents, but it's quite another to point at a case like this and say, "Look!  People are dying!"

4. Getting Rid Of Fantasy Numbers In Copyright Debate: I enjoyed this post for two reasons.  First, I grew up routinely hearing the saying: figures don't lie, but liars figure.  The point being, of course, that facts are beautiful things, but the methodology for arriving at numbers can be extremely important.  Second, some of the negative comments from the community truly made me laugh ("it does not matter at all, what the actual numbers are").  Awesome in its simplicity.

5. One Way To Deal With Child Bullying: Have The Whole Internet Stand Up For You: As I'm sure all of you can tell, I'm just a big ol' softy at heart.  I like chick flicks, puppies, and grandmas.  But more than all of those, I adore stories that illustrate the good in people.  To hear of this example of a large group of people offering encouragement, aid, and support warms the cockles of my heart.  Plus I'm a huge Star Wars fan (who'd have guessed?).

DailyDirt: Launching Rockets And Satellites

Getting into space is getting cheaper as more countries and more companies are able to launch space-worthy rockets. The space shuttle may be retiring, but unmanned missions seem to be (mostly) progressing nicely. It might be inspiring to see humans in space, but it seems far more practical to get more missions up and to explore with robots -- as long as the robots obey us. Usually, they do.

  • SpaceX's Falcon 9 rocket successfully put its Dragon spacecraft into space. The privately-owned spaceship also made it back to Earth. Rinse. Lather. Repeat... And profit? [url]
  • NASA launches a nanosatellite from a microsatellite. I wonder if the Russians ever put a matryoshka doll in space... [url]
  • Schools can request a space shuttle heat shield tile from NASA. And it's only a matter of time before these tiles are auctioned off on eBay for school fundraisers. [url]
  • A malfunctioning satellite is taking out US weather services and could strike again. Remotely rebooting satellites ain't easy. [url]
  • Japan's Akatsuki probe missed Venus orbit, and now JAXA will have to wait 6 more years to try again. Betcha can't add 6 years to a human space mission as easily. [url]

    Android Market Gets A Badly-Needed Facelift (But Web Purchasing Is Still MIA)

    I've been an Android fan for a while now, but I can't remember the last time I had anything good to say about its integrated application marketplace, Android Market. Compared to the iPhone's App Store, Market's experience has always looked less visually compelling, and in general it's been harder (and less fun) to navigate. �Today, the Google team has announced that Android Market will be getting an upgrade over the next two weeks.�And good news: this update will be going to all Android users who are on version 1.6 or higher, which means it will go out to the vast majority of devices. I haven't gotten access to the application yet, but judging by the screenshots the Market has gotten a fresh coat of paint, and looks much more modern. Promoted applications ?�which until now have been tiles at the top of the screen that would change every few seconds ?�will now be featured in a swipable view that looks a lot like Apple's CoverFlow.

    Venezuelan Politicians Seem To Think The Web Is Like TV: Adult Content Only Allowed At Night

    With all the jokes we've had about how badly it seems the US government doesn't understand the internet, and often seems to want to censor the internet, it appears that politicians in Venezuela want to go even further. A lawmaker from the ruling party has put forth a bill that would regulate the internet -- in part by saying that adult content can only be available after midnight.

    Yes, you read that right. Supporters point out that this is the same requirement for TV and radio, so why shouldn't it work that way for the internet? Detractors point out that... um... that's not how the internet works. Of course, the bill also lets the government directly censor websites that say things the ruling party doesn't like, which does seem like standard practice for media entities in Venezuela these days.
