Gemini-Scout Will Be the First One In to Rescue Trapped Miners

Nobody wants to venture into a mine after an accident, but the people who least want to be in there are those who might be already trapped inside. Rather than ask for human volunteers to go in and check things out, Sandia National Labs has developed a robotic platform that doesn't have a choice, called Gemini-Scout.

Collapsed mines offer all kinds of obstacles that threaten to suffocate, burn, crush, drown, electrocute, or otherwise impede even the toughest of robots. With this in mind, Sandia has done their best to mine-proof Gemini-Scout, which can clamber over rubble, wade through up to 18 inches of water, and not cause huge methane gas explosions thanks to sealed and spark-free electronics.

As capable as Gemini-Scout is, it doesn't come with an attached multidimensional quantum escape tunnel or anything. While the robot is theoretically capable of dragging a human behind it, its primary mission is to scout ahead to send back video and sensor readings to help an actual rescue team safely and quickly get where they need to go. In the short term, the robot can also deliver vital supplies such as food, water, medicine, air packs, radios, and Sony PSPs to any miners who may be trapped out of immediate reach.

It sort of seems like a robot with Gemini-Scout's capabilities would be good for more than just working in mines, and that may be the case, but Sandia seems to be pretty focused on optimizing Gemini-Scout for this one task. Their primary customer at this point is the Mine Safety and Health Administration, and miners can look forward to having a robot ready and willing to help them out when Gemini-Scout enters service next year.

Weird UAV Demos: Lockheed Martin's Samarai and Aerovel's Flexrotor

I love weird UAVs. I don't mean "weird" in some kind of bad way, but more like, "different" and "creative" and "unexpectedly awesome." These two flying robots, Lockheed Martin's Samarai and Aerovel's Flexrotor, both display innovative and unique designs that highlight some of what's possible when you combine robots and imagination. And, you know, funding.

When we last talked to Lockheed Martin about their Samarai project, they were hard at work making their spinning maple seed-inspired robot into a practical surveillance flyer. Last year, the Samarai project's principal investigator, Kingsley Fregene, explained to us what exactly this design has to offer:

"The Samarai is inherently stable in hover, mechanically simple and has very few moving parts. This makes it a very robust aerodynamically clean airframe, just like nature’s samaras. It does not depend on fragile feathers, delicate wings or precision moving parts to operate. This design was chosen because of its versatility, ease of operation, multiple launch and recovery options (even in tight spaces) and its ability to hover and take-off/land vertically. The rotation of the entire aircraft offers opportunities to achieve omni-directional sensing in a much simpler, lighter-weight and cheaper package."

From the sound of things, those opportunities have been largely realized, since according to Lockheed Martin's press release, they just finished 3D printing a Samarai vehicle last week (!) that flies using a grand total of two moving parts and can stream back live 360 degree video without needing a gimbal.

There's been a video floating around this past week of the Samarai drone in action, but it's from last year. This video, however, shows the latest version being demoed at AUVSI, which just opened its doors for the 2011 expo yesterday. Apparently, this was the very first time that Samarai had been demoed to the public, and the fact that it was flown without a tether shows that Lockheed has either a.) a reckless disregard for spectator safety or b.) a lot of faith in their ability to control a robot that flies while spinning in circles really fast:

No decapitations! Brilliant!

Samarai's hover capability makes it a great surveillance bot, but the big trade-off is range, since helicopters (and helicopter-like robots) are simply not as efficient as aircraft that can utilize static wings for lift. This is the idea behind vehicles like the V-22 Osprey: It's a helicopter when you want to hover or land, and the rest of the time, it's an airplane. Aerovel's Flexrotor aircraft has taken this idea and condensed it into a "tabletop-sized" surveillance drone that can take off vertically, transition to forward flight, and then land vertically again on a specially built platform:

Slick. In this way, Flexrotor offers all those useful VTOL features, along with an endurance of 36 hours and a range of up to 3,000 kilometers. It's hard to say whether this technique is better or worse than some of the other innovative fixed-wing drone capture solutions that we've seen, but the fact that hovering is useful in many other situations makes Flexrotor potentially much handier to have around.

MABEL Bipedal Robot is Fast Enough to Run You Down

It was only a year ago that the University of Michigan's MABEL biped robot was breaking its ankles trying to walk over rough terrain. Now the robot is defying death once again by becoming the world's fastest bipedal robot, with the ability to sprint at up to 10.9 kph. More specifically, MABEL is the world's fastest "kneed" bipedal robot, which just means that it's the fastest robot that can run in a similar manner to us humans, leaving those Toyota robots (4.3 kph) and ASIMO (3.7 kph) in the dust.

MABEL is capable of such blistering speeds thanks to an innovative mechanical design which, although it may not look like it, incorporates a lot of the characteristics of a human runner. For example, MABEL has a torso that's substantially heavier than its legs, just like a human, and it's also got a system of springs that act like tendons. This gives MABEL a very human-like, bouncing gait, and the robot spends 40% of its time running in a "flight phase" with both feet off the ground, similar to humans:

For reference, MABEL's top speed of 3 meters per second probably isn't enough to catch a tolerably in-shape human, as Olympic sprinters can run at up to 10 meters per second over short distances. But the thing about robots is that they're determined, so in the end, it's a good thing that MABEL is tethered to that pole. And that it doesn't have any arms to grab you with. Or any vision sensors, either. So even if you can't run, at least you can hide.

For now.

Swarmanoid Robot Teams Up with Itself to Steal Your Books

I don't know what it is that Swarmanoid actually does with the books that it steals, but the robot (or, a piece of the robot) has been pilfering them since back in 2009. At least stealing books is better than stealing kids, which is what Swarmanoid's predecessor did to keep itself busy. It's tough to call Swarmanoid a robot (singular), since it's made up of a swarm of dozens of separate robots, but it's equally tough to think of it as separate robots, since the individual members of the swarm depend on each other so heavily.

Putting grammar aside, the Swarmanoid swarm consists of three discrete types of robots, all of which we've been introduced to before: Foot-Bots can grab onto other robots and move horizontally. Hand-Bots have manipulators and a freakin' sweet magnetic grappling hook that lets them move vertically. And Eye-Bots can fly, perch on ceilings, and direct the movements of the Hand-Bots and Foot-Bots with their cameras.

We've been watching these swarm-bot modules evolve since 2007, and the following video (which won an award for best video at the 2011 Artificial Intelligence Conference last week) is the first that we've seen showing all of the bots seamlessly and autonomously cooperating to execute a task:

While trying to manage so many robots all at once may seem needlessly complicated, a swarm of robots has all kinds of advantages: swarms are adaptable, scalable, resilient, cost effective, and very efficient at any task that involves being in more than one place at once, like search and rescue (or search and steal). There are downsides, too, like having to recharge each and every one of these little guys, but with some epic amounts of cleverness by robotics researchers, robot swarms are getting to the point where they're able to pretty much take care of themselves, and after that, the sky's the limit.

Unless you have an Eye-bot, in which case it isn't.

Video Friday: Surface Control, Research Robotics, and My Robot is Better than Your Robot

 microsoft surface robotics control

A bunch of cool robot vids have shown up in the last few days, so I thought I'd toss 'em all up for you to enjoy since it's Friday and you're probably not going to be doing anything especially productive anyway.

Microsoft Surface is one of the coolest interfaces I've ever had the pleasure of fondling, and it makes one heck of a robot control system:

You may think of research robots as tools (and even as simply a means to an end), but they think of you as a friend:

This film by David Lu, which premiered at the Robot Film Festival last month, reminds us all: be nice to your robots. They love you.

While celebrities agree that science in general is pretty cool, they also agree robots are by far the coolest. Two things: how do I get this song as a ring tone, and who the heck is this "Justin Bieber" fella?

According to the Facebook page, " FIRST: Science is Rock and Roll" is a back-to-school special that blends entertainment, science, technology, AND ROBOTS. And also lack of understanding about period use, it looks like. You can tune in on ABC this Sunday at 7, and "Justin Bieber" will apparently also be involved, for whatever that's worth.

Willow Garage Introduces PR2 SE, Half the Arms at Half the Price

Yesterday, Willow Garage announced the availability of an entirely new robot. Or maybe not an entirely new robot. The PR2 SE is essentially the same as a PR2, except that (as you may have noticed from the picture) it's only got one arm.

Despite having only half the armament of the original PR2, the SE boasts the same overall capabilities, along with an "updated sensor suite" that includes an integrated Microsoft Kinect. Lack of an entire arm may seem like a fairly significant issue for a robot, but many things that you can do with two arms you can also do with one, it just may take longer or require a bit more creativity.

If you do end up desperately needing another arm for your SE, you can buy one as an upgrade from Willlow Garage. Or you could build a slightly less fancy version on your own. Or, you could get yourself a LASER CANNON and bolt that in instead! YEAH! And anyway, as long as you make sure that the robot is only visible from the right side in your lab, you'll be able to fool people into thinking that you've got an original PR2, and at the end of the day, that's what really counts.

Taking a big chunk out of the robot also takes a big chunk out of the price, which is the whole point of the SE version. The base price of the new PR2 SE is $285,000, and with Willow's 30 percent open source discount award, that comes down to just under $200,000. This is half the price of the fully armed and operational regular PR2, which costs $400,000 if you buy it straight up. So If my calculations are correct, this means that I should be able to get a PR2 with zero arms for free, right? Please...?

Neato XV-11 Update: Your Vacuum Just Got Smarter

The Neato Robotics XV-11 robot vacuum comes with a USB port for downloadable updates. And why shouldn't it? It's a robot, and one of the great things about robots is that you can teach them new stuff and make them smarter. While it's one thing to talk about firmware updates and new features in the abstract (which we hear a lot), it's quite another to put time and energy into developing them, and it's something else entirely to then offer said upgrades to your customers for free. This is what Neato has decided to do with the 2.1 version of their vacuuming software.

All you have to do is plug your robot into a computer (PC only, for now) with a regular old USB cable, download a little piece of software, and when the upgrade finishes, your vacuum will all of a sudden be intelligent enough to do the following:

  • Clean one specific 4' x 6' area with a new "spot cleaning" mode

  • Detect when it's tangled in carpet fringes, stop its brush, and back away

  • Clean faster and more reliably with many small navigation enhancements

  • Perform a "wiggle" while docking to ensure a good charging connection, even with dirty contacts

  • Understand English, Spanish, French, German, Italian, Chinese, and Japanese

These improvements were designed and implemented through rigorous in-house testing as well as feedback from users. The changes to the docking procedure, for example, are a response to a problem that a few people encountered in some very specific situations that Neato nonetheless put some hard work into figuring out how to fix.

I'm a big fan of companies who stand behind their products to the extent that they're willing to continue to make them better even after you've already bought one. And this upgrade isn't just fixing a bug or patching a security hole, there are entirely new features that you get without having to buy anything. Neato says that this type of support for their robots is likely to continue, which is great news, since I'm still waiting for the upgrade that lets my XV-11 use its laser to keep my cat from clawing the drapes. ZAP.

$500 RC Truck Is an IED Detecting Robot That (Should Be) Affordable for Everyone

Robots like iRobot PackBots are great tools for (among other things) detecting IEDs, and they've managed to save the lives of countless soldiers, often by sacrificing themselves. Not every soldier (or even every squad) gets a PackBot, though, since the robots cost a lot of money: this 2010 contract suggests that we're looking at over $125,000 for a new iRobot PackBot 510 system.

At this rate, it's gonna be a while before every soldier can rely on a top of the line EOD robot, but in many cases, a top of the line robot (that costs a hundred thousand dollars) is overkill, or at the very least, not strictly necessary to still provide a valuable contribution to a squad of soldiers. Take the RC truck in the above picture. It's pretty fancy, as RC trucks go, with a top speed of 60 mph and costing several hundred dollars. That wireless surveillance cam may have added another couple hundred or so. The system was shipped to Afghanistan by the brother of a soldier stationed there, who used it scout for IEDs from the distant safety of an armored Humvee. A couple weeks ago, the little truck was vaporized when it managed to set off a 500 pound IED that might have otherwise been triggered by the Humvee itself, and this is the fifth IED that the truck has detected, although the first one that it's actually set off.

Here's an excerpt from an ABC News email interview with the soldier who was using the truck:

In his email, Chris Fessenden said the little truck has successfully found four IEDs since he first got it.

"We do mounted patrols, in trucks, and dismounted by foot," he wrote. "The funny thing is the Traxxis does faster speeds than the trucks we are operating in under the governing speed limit... so the traxxis actually keeps up with us and is able to advance past us and give us eyes on target before we get there."

"Is it a toy?" he wrote. "Yeah it it fun... absolutely... but the guys here take the truck very seriously when out on [a] mission."

$500 is really, really cheap, especially when you consider how many lives this little thing has saved. Would it be too much to ask for the military to spend a relatively infinitesimal amount of money and just ship a bunch of these direct to Afghanistan? Apparently it is, because the guys who had the idea originally have set up a charity specifically to send as many toy trucks to Afghanistan as they possibly can. Feel free to donate here.

PR2 and TurtleBot Team Up to Bring You Drinks

PR2 and TurtleBot robots at Bosch

I love how so much of what's recognized as practical robotics research nowadays seems to be largely motivated by programmers who are hungry, thirsty, bored, and too lazy to do anything about it themselves: "well, I could go get myself a drink, or instead I could just program this robot to get me one instead! Yeah, let's do that!"

In practice, of course, there's no laziness involved, and the problems tackled by these demonstrations are complex and highly relevant to everything from object recognition to grasping strategies to autonomous navigation. So what if successful completion of a task happens to involve a tangible reward for those hard-working roboticists? They've absolutely earned it.

This latest hackathon from Bosch's research lab in Palo Alto, Calif., involves a PR2 and a TurtleBot joining forces to take drink orders over the internet. The Bosch PR2, named Alan, is tethered to a ceiling-mounted power plug, so he's in charge of handling the fridge, choosing the right drink, and picking it up, while the TurtleBot (named BusBot) takes care of the actual delivery:

It does kinda look like the guy who gets the drink at the end is not the same as the guy who ordered the drink in the first place, but that's understandable. I'm sure to a robot, all us biological meatbags look pretty much the same.

Hexapod Robot Plays Beethoven

chiara piano playing robot

Just like humans, every robot comes with its own unique musical stylin'. Well, mostly unique. Except for the ones that are made from all the same parts with identical programming. But this hexapod, Chiara, has certainly found a comfy little niche for itself in the robotic classical piano world, by plonking away at some Beethoven. I love how this video takes us through the thought process of the robot (or whatever you want to call it), from raw vision to blob detection to kinematics. Have a listen:

Chiara itself is an open source educational robot developed by Carnegie Mellon University. It runs a free programming language called Tekkotsu, and this particular demo was put together by Ashwin Iyengar, a high school student. Nicely done, Ashwin, and good choice of music.
