German robot arm learns ping-pong as it plays humans, might rival its masters
We like to tell ourselves that learning by doing is the best strategy for improving our skills, but we seldom apply that philosophy to our robots; with certain exceptions, they're just supposed to know what to do from the start. Researchers at the Technical University of Darmstadt disagree and have developed algorithms proving that robot arms just need practice, practice, practice to learn complex activities. After some literal hand-holding with a human to understand the basics of a ping-pong swing, a TUD robot can gradually abstract those motions and return the ball in situations beyond the initial example. The technique is effective enough that the test arm took a mere hour of practice to successfully bounce back 88 percent of shots and compete with a human. That's certainly better than most of us fared after our first game. If all goes well, the science could lead to robots of all kinds that need only a small foundation of code to accomplish a lot. Just hope that the inevitable struggle between humans and robots isn't settled with a ping-pong match... it might end badly.
New periodic table element names confirmed, textbook makers sigh in relief
What's in a name? If you're the general assembly of the International Union of Pure and Applied Physics, then quite a lot. It's that bunch who have finally rubber-stamped the names of elements Darmstadtium (110), Roentgenium (111) and Copernicum (112) on the Periodic table. The trio are so named in honor of Darmstadt (where it was first created), Wilhelm Röntgen (discoverer of X-Rays) and Nicolaus Copernicus (explaining the universe since 1533). All three elements are "super-heavy", lab-created substances that rapidly degrade down into less interesting materials -- Copernicium-285 has a relatively long half-life of 29 seconds. The ratification went without a hitch, causing a sigh of relief amongst the textbook makers who have included the elements in the table for quite some time. Although we were hoping that element 111 would have to change its name back to the original, nearly unpronounceable unununium. [Image courtesy of the BBC / Talkback Thames]
RoboCup Soccer 2010 finals show impressive realism by feigning injuries (video)
The World Cup may still be ongoing (despite what the US, England, and a handful of others may think), but the RoboCup 2010 in Singapore has just closed shop with an edge-of-your-seat display of autonomous action. The final game came down to two German teams, the Darmstadt Dribblers and the FUmanoids. As seen at numerous points, both android teams have even learned the ancient art of diving, toeing the uncanny valley a little to close for comfort. Video after the break -- we won't to spoil the ending, so let's just say Germany won by a sizable margin. If fierce competition isn't your cup of tea, we've also got footage of DARwIn-LC, a low cost (hence the name) humanoid from our friends at Virginia Tech's RoMeLa. These adorable little guys cost about $2,500 apiece and will be going out to 11 of VT's partner universities. Update: Dr. Dennis Hong himself sent us a few clarifications. The DARwIn-LC is a collaboration between RoMeLa and the company Robotis. No price has been disclosed, but the $2,500 is incorrect. Additionally, the robot is being planned as a "true 'open platform.'" In Hong's words, "we are "planning" to post all CAD drawings, fabrication and assembly manuals, and also the basic software on-line for free. Thus any one with certain equipment, budget, and skills will be able to make one them selves - or purchase the entire thing or parts from Robotis. We want to form a community of DARwIn-LC users to share new ideas for improvement, hack it, etc. and use the robot for research, education, outreach, and of course, an easy entry point for the RoboCup humanoid division."

The DS Life: Out of habit
Though we try to keep our praise of public property vandalism to a minimum, there are some instances when we can't help but clap in our seats, humorless, like Orson Welles in Citizen Kane. This week's edition of The DS Life is one of those instances, our subject being a magnificent bit of street art spotted in Darmstadt, Germany and photographed by Joachim S. Müller. Say ten Hail Marys and bring yourself past the post break for the photo.
