The famous ‘Big Dog’, a quadruped robot with a characteristic life-like appearance evolved into the new Legged Squad Support System (LS3), which recently underwent its first outdoor test. The new LS3 like its predecessor is a highly mobile, semi-autonomous legged robot. It use vision sensors (DARPA calls them ‘eyes’) to follow a person and also to map its path while avoiding or navigating over obstacles like rocks, trees etc. Over the next 18 months it will be tested thoroughly in order to be able to operate along a squad of Marines or soldiers. LS3 should carry 400lbs of cargo on a 20 mile trek in 24h without refuel. It could follow a specific person, track people, objects and the terrain in front of it while creating its own course. Along with its vision sensors, “hearing” technology will be added enabling soldiers to address it and command it with simple orders like “stop”, “sit” etc. The end result will be similar to a clever robot mule that will follow and obey to simple commands. You can find more info in DARPA’s press release and at the website of Boston Dynamics.

Using hardware developed by KMel Robotics, Alex Kushleyev and Daniel Mellinger, of UPenn's GRASP Lab, working under the direction of Professor Vijay Kumar, and with assistance from Associate Professor Daniel Lee, have demonstrated coordinated flight of as many as twenty nano quadrotors.

David Anderson, a long time member of the Dallas Personal Robotics Group, did an interesting presentation recently in which he distills down what he's learned about building subsumption based mobile robots over the years. The video is a bit long but well-worth your time if you're interested in intelligent robots. David provides some additional notes that link to video of specific examples. And don't forget to check out David's "my robots" webpage for more photos and details on his robots.

The Uncanny Valley has been called upon to explain why Mitt Romney's persona disturbs so many people despite general agreement that he's a "successful, good-looking family man". Like Democrat Al Gore in previous races, Republican Mitt Romney creates a strange unease even among his supporters. A recent essay in the Atlantic provides an explanation for this phenomenon based on the Uncanny Valley theory that we are repulsed by slight imperfections in human-like action. The author argues that Romney's personality exhibits traits which put him into an "uncanny valley" for politicians.

"Most politicians tend to be ordinary-looking people who spend their time convincing voters they're office-quality material. Romney is rushing the other way: he's the politician from central casting who is stumbling through an audition for a role of regular human."

There were lots of jokes and comments about Al Gore being a "robot" in earlier races. But here we've got a more detailed attempt at explaining what makes people uncomfortable about this type of politician. This raises interesting questions: 1) is this just an amusing analogy or could there be any real psychology behind claims of a political uncanny valley? 2) does a reference to the uncanny valley by a political pundit mean even relatively obscure robotics and AI science is going mainstream? 3) if even some humans fall into the uncanny valley, is it more important that robots climb the other side or that we adjust our expectations of intelligent behavior?

In the new episode of Robots Podcast we talk to Subramanian Ramamoorthy from the University of Edinburgh about the recent progress in walking robotics. We then speak with Felipe Brandão Cavalcanti, an Electrical Engineering student working on bipedal walking at the LARA lab at the University of Brasilia with Professor Geovany Borges. Ramamoorthy tells us about the recent advances in humanoid bipedal walking illustrated by Petman and the latest version of Asimo. In particular, we look at the history of the field with work from Mark Raibert, Russ Tedrake andDaniel Koditschek and how different areas, such as machine leaning and motion capture, come together to accelerate progress. Felipe Brandão Cavalcanti's project focuses on the study and implementation of gait generation and stabilization algorithms for small humanoid robots. He tells us how they hacked a humanoid toy to improve its balance and the importance of math in his work.To learn more about walking robotics read on or tune in!

While this won't matter to most readers of Robots.Net until a version with English subtitles becomes available for download, SVT's Akta Manniskor starts tomorrow, January 22nd. A ten hour series following the stories of a handful of "hubots" - human-like robots we might prefer to call androids - and the humans into whose lives they become entwined, the release of this Swedish production has been preceded by a bit of guerrilla marketing, and there is a making-of video available, also in Swedish of course.

Shermine of Universal Robots, a Danish company, writes to tell us about a light-weight robot arm and matching touch-screen controller they've just completed. We also got word of a new robotics and AI blog called NooTriX, check it out. For our LEGO fans, Simon tells us about WorldBricks, a website where you can download LEGO instructions and catalogs dating back to the 1950s. Guy Cefalu sent a link to the Element microcontroller for .NET developers. No specs on memory or CPU type yet but looks like a PIC. (bonus points to the first reader who posts instructions for using an open source compiler like SDCC with this one!) The Swirling Brain spotted an instructable for a tiny robot called the Roule_Robot, just 14g and 39x22mm. Finally, Colin Adamson wrote to tell us about the Kickstarter campaign for his OCULUS Surveillance and Telepresence Netbook Robot (which looks a bit like the old Evolution ER1).

It appears Justin Bieber got around at CES. So did the GeekBeat.tv crew, including to the XYBOTYX booth, where they recorded the XYBOT rolling around on a wooden platform.

In Robots Podcast episode #95 David Lane, Professor of Autonomous Systems Engineering and affiliated with the Heriot-Watt University Ocean Systems Laboratory (Edinburgh), talks with interviewer Per Sjoborg about his journey from research to business and back. He tells about how he got started first in offshore work then in robotics research, developing control software for autonomous underwater vehicles. He also tells how frustration with the lack of utilization of his work led he and his associates to start the company SeeByte, to commercialize it, and how having the U.S. Navy as their first customer proved very helpful towards the company's success. (Dr. Lane has much to say about the value of customer funding and customer focus for a startup.) Finally, he tells about his return to academia after finding the right person to take over the day-to-day details of running SeeByte, and how his experience in industry finds its way into his academic work.

CES is nearly over, but we have a few more items to share. The Inventist SoloWheel, shown above, was panned by The Verge as having zero chance of making it to the mainstream. As may be, pending further development, but the company provides an assortment of videos on its website. Without having tried it myself, I doubt it requires more skill than rollerblades. NEC showed its Communication Robot PaPeRo, a research prototype, not yet for sale, along with an Android app that allows users to control the robot remotely. There were Dancing Cats and Baby Seals, and a robotic vacuum cleaner that entertains while it works, and is itself cleaned out each time it docks. And last, but far from least, TechCrunch interviewed Bre Pettis of Makerbot about their new Replicator model, and the future of 3D printing.

You've probably already heard about the event wherein Justin Bieber was enlisted to introduce TOSY's new mRobo at CES, but you may not have learned much about the device itself or the company that makes it. mRobo is a combination music player and dancing robot. It can store 2 gigabytes worth of music in its own memory, or stream it via bluetooth, or simply listen. In any case, when there's music playing, it sprouts a head, arms, and legs and begins to dance in time to the beat. The price is set at $199, and you won't be able to get one until later this year.

The video above shows iRobot's Ava telepresence platform paying a visit to the crew of The Verge, in their trailer at CES. Other exhibitors of interest include Parrot, showing their AR.Drone 2.0, and Sphero, with their iPhone-controlled ball. More to come.

The video above is an informal (always with Cali Lewis), very upbeat interview with Gary Shapiro, CEO of the CEA, sponsors of CES. Besides Cali and crew, The Verge and Engadget are also prowling the floor at CES 2012, and IEEE Spectrum is also covering the event. All four sometimes talk about robots, and we know there are robots there, so we're hoping for decent coverage, the best of which we'll be passing along.

Robots figure more prominently at this year's CES than ever before. Among the many presenters are Modular Robotics, whose Cubelets are shown above, and XYBOTYX, developers of the XYBOT, a small two-wheeled balancing device that turns an iPhone into a telepresence robot.

The mailbox has been filling up with interesting stories lately, like a pair of conflicting papers from the Current Directions in Psychological Science journal. One claims that Darwin was wrong to suggest that facial expressions have innate connections to particular emotions, while the other supports the idea that facial expressions evolved to communicate emotional states, playing a crucial role in survival. There's also new evidence that chimps have a theory of mind, which has implications for the development of language. If all this talk of mind and emotion is too boring, Hank Pellissier over at IEET, wrote a piece Sexbots for Women, pondering why only males are assumed likely to desire sex with androids. The Swirling Brain noticed a Huffington Post story on Google's cloud robotics initiative. Know any other robot news, gossip, or amazing facts we should report? Send 'em our way please.

The Robot Film Festival will soon begin accepting submissions for the 2012 competition.

The Navy Research Lab has completed testing of a Balloon-launched UAV that in turn launches smaller UAVs. They're calling the project ADD (Autonomous Deployment Demonstration) A balloon carried an UASUSA Tempest UAV to 60,000 feet. On each of the Tempest's wings, a smaller CICADA Mark III autonomous glider was mounted (CICADA stands for Close-In Covert Autonomous Disposable Aircraft). The smaller UAVs were then launched and autonomously navigated to within 15 feet of predetermined waypoints. The goal is demonstrate that the robots could provide a low cost way of placing precision located sensors for reconnaissance. For more photos of the operation, see the Navy's press release

In the final episode of Robots Podcast for 2011, the interviewers reprise some of the highlights of the year, of which there have been many to choose from. Some of those mentioned are represented in a YouTube playlist. Another YouTube playlist collects submissions received in response to an appeal for Christmas-themed videos featuring robots. From the Robots Podcast team, we wish you an even better 2012.
