Back in July, we wrote about how UPenn’s GRASP Lab had taught their quadrotors to work together to grasp and move things. The next step, it seems, is teaching the quadrotors to work together to grasp and move things and actually build buildings. The video above shows a team of quadrotors cooperating to construct the framework of a (rather small) building. The building’s structure is held together with magnets, and the quadrotors are able to verify that the alignment is correct by attempting to wiggle the structural components around, which is pretty cool. It’s fun to speculate about how this technology might grow out of the lab into the real world… To build actual buldings, you’d either need much bigger quadrotors (which is possible), lots of small quadrotors cooperating in big pieces (also possible), or buildings built out of much smaller components (which might be the way to go). The quadrotors probably wouldn’t be able to do all the work, but they have the potential to make construction projects significantly more efficient. [ GRASP ]

It looks like that desert testing we wrote about in May of last year has paid off, and UPenn’s KodLab has developed a new version of their RHex wheeled/legged robot called X-RHex. X-RHex is about the same size and weight as RHex, but it’s stronger, more durable, and has as longer run time of up to two hours. It’s also got a couple mil-spec rails mounted on top along with standardized electrical connections, which could be just for convenience or could be because X-RHex has a probable military future, or both. X-RHex doesn’t seem as capable of the speeds exhibited by other leg/wheel hybrid robots such as Whegs, but its strength is in its adaptability and the way it can make it through basically any sort of terrain, even things that would challenge conventional wheeled or tracked robots.

The T-1000 shape-shifter robot in ‘Terminator 2’ serves as a terrifying upgrade over its Arnold predecessor. But, that intimidation doesn’t arise from its morphing capabilities, because the robot truly horrifies us when it breaks into — with those disturbing swinging arms — an emotionless, unflinching sprint. Well, finally, an engineer has decided real robots should possess those same stupefying skills. MIT scientist Ryuma Niiyama is developing a running robot, simply named ‘Athlete,’ that employs seven complex muscle systems. The artificial muscles, which mimic human sets like the gluteus maximus and the hamstring, power prosthetic blades similar to those utilized by amputee athletes. Embedded sensors and inertial measurement units monitor the bot’s orientation, so that it — conceivably — can maintain a steady, sickening sprint.

GLENN GREENWALD: Well, I just want to underscore how alarming everything is that you just described, both in that report and in your earlier one, which is, whatever you think of WikiLeaks, they’ve never been charged with a crime, let alone indicted or convicted. And yet, look at what has happened to them. They’ve been essentially removed from the internet, not just through a denial of service attacks that are very sophisticated, but through political pressure applied to numerous countries. Their funds have been frozen, including funds donated by people around the world for his—for Julian Assange’s defense fund and for WikiLeaks’s defense fund. They’ve had their access to all kinds of accounts cut off. Leading politicians and media figures have called for their assassination, their murder, to be labeled a terrorist organization. What’s really going on here is a war over control of the internet and whether or not the internet can actually serve what a lot of people hoped its ultimate purpose was, which was to allow citizens to band together and democratize the checks on the world’s most powerful factions. That’s what this really is about. It’s why you see Western government, totally lawlessly, waging what can only be described as a war on WikiLeaks and Julian Assange outside the bounds of any constraints, because that’s what really is at stake here. If they want to prosecute them, they should go to court and do it through legal means. But this extralegal persecution ought to be very alarming to every citizen in every one of these countries, because it essentially is pure authoritarianism and is designed to prevent the internet from being used as its ultimate promise, which is providing a check on unconstrained political power.

Why, it’s another robot-themed hotpot restaurant! This time we’re looking at Jinan — once famous for demolishing a whole stash of illegal arcade machines — up in north China, where a ballsy robotics manufacturer started trialling a robot-themed eatery. While there are still human chefs working back in the kitchen, some near-hundred customers will be served by six robots (about ¥40,000 or $6,000 each to build) that follow a white line to seat diners and deliver dishes. Oh, and don’t expect any slapstick comedy here — these bland-looking droids will only stop if you dare stand in front of them. You’ll have to hurry up, though, as this venue closes in about 16 days; but for those who can’t make it, we’ve got a video right after the break.
