Apple's rumored AR headset may pack 8K displays and VR support
Those rumors of Apple making an augmented reality headset just got a little more concrete. A CNET source claimed that the stand-alone device (codenamed T288) would also support virtual reality, and would have an 8K display for each eye. For reference, even the HTC Vive Pro is limited to 'just' 1,440 x 1,600 per eye. If this is accurate, Apple could effectively eliminate the screen door effect you often get with current VR, where the proximity of the display lets you see the gaps between pixels. The improved realism might also help fend off motion sickness for some wearers.
Robot research firm Willow Garage closes its doors (update: thankfully untrue)
Rumors of Willow Garage's death may have been very premature, but they've come true all the same. Businessweek reports that company founder Scott Hassan shut down the robotics research pioneer in January to become the dedicated CEO of Suitable Technologies, Willow Garage's telepresence-focused spinoff. The closure means that you won't be seeing follow-ups to machines like the PR2 or TurtleBot 2. However, the firm may have created an enduring legacy through its open source robotics platform -- when Baxter and numerous other automatons are using the code, you could be hearing about Willow Garage's work for some time to come. Update: We've gotten in touch with Willow Garage, and it turns out that rumors of the company's death have been greatly exaggerated... again. While it did move some staff to Suitable Technologies back in August and offloaded support services to Clearpath Robotics, it's still very much in the robot business. Also, the company notes that Hassan has been the CEO of Suitable for roughly three years. It's not clear where Businessweek obtained its info, but it's good to know that Willow Garage is alive and kicking.
Willow Garage talks TurtleBot 2 (video)
Want to try out ROS (Robot Operating System) on an official Willow Garage product, but don't have the $400,000 required to pick up our old pal, PR2? You're precisely the audience the company is looking to hit with the TurtleBot, a (relatively) low-cost robotics kit (around $1,500) that looks a bit like small shelving united seated atop a Roomba. A couple of months back, the Bay Area-based company unveiled a sequel built on top of a new base, Yujin Robotics's Kobuki, which promises more speed, letting the plucky little 'bot run over small bumps. Pick up the full kit and you're also getting a Kinect sensor and a low-end laptop. Willow's also got some add-ons like a small robotic arm that you can use to modify the thing. Stay tuned after the break to check out video of the 'bot's creators talking up the reptilian robot.
Qbo, the open-source robot, interacts with people, makes adorable mistakes (video)
A while back we got a detailed look at the innards of Qbo, TheCorpora's open-source robot. But we haven't gotten to see the little guy in action -- until now. His handlers recently let him loose to run autonomously, guided by a pair of webcam eyes and voice recognition courtesy of Willow Garage's ROS software. The team soon noticed some unexpected behavior, though. Despite being programmed to follow humans at a specific distance, Qbo trailed uncomfortably near with taller people -- probably the first example of a robotic "close walker." Poring over the log files revealed why: proximity was calculated based on faces. The faces of taller people were farther away from the ground-hugging robot, which adjusted accordingly. Roll your way down the page to see more of our cute mechanized friend, and over to the source link for more musings on programming him.
POLYRO humanoid robot can be built by you, looks more like K-9 than C-3PO
It may bear closer resemblance to an upright dog than a human (check out those ears!), but POLYRO here is the least frightening example of a do-it-yourself robot that we've seen to date. We're not sold on the humanoid's name as an acronym (oPen sOurce friendLY RObot), and the instructions and assembly photos are rather hit or miss, but this rollin' rover definitely scores some points for looks. Prepare to get down and dirty with a jigsaw, drill press, and "safety equipment," before the latest addition to your family is ready to roll across the living room floor on its iRobot base. Instructables has posted a full shopping list, including a 10.1-inch netbook, ROS (Robot OS), and a Kinect. If you're feeling brave, clear some time in the schedule and space in the garage after heading over to our source link.
BiliBot combines Kinect, iRobot Create and gripper arm for affordable ROS fun (video)
The Personal Robotics Group at MIT may have already strapped a Kinect to a iRobot Create, but BiliBot did them one better by adding an arm to the mix -- not to mention this cherry-red frame. Better yet, you can order your own BiliBot Developer Edition now for the affordable price of only $1,200. OK, maybe calling $1,200 "affordable" is a bit of a stretch, but in the world of programmable robotics that's not half bad, especially when you consider this self-contained robotics platform comes with its own Ubuntu-booting Core i3 computer with 4GB of RAM. The preinstalled ROS software can be used to steer the bot using data gathered through the battery operated Kinect and also to control the arm, which is connected to geared motors instead of more traditional servos. Those motors allow the BiliBot to lift three pounds up to a height of 17 inches -- perfect for beer delivery, provided you're sitting. Watch it navigate a relatively obstacle-free room in the video after the break. [Thanks, Travis]
Meka's M-1 Mobile Manipulator, a cuter Cody the spit bath robot (video)
Remember Cody? The robot from Georgia Tech designed to give spit baths to the elderly and crippled? Well, Cody's got an attractive younger cousin named M-1, and for $340,000 this fine piece of machinery could be all yours. Built by San Francisco-based Meka Robotics, the M-1 Mobile Manipulator (based on Cody) runs on a combination of ROS and proprietary software and sports a Kinect-compatible head with a five megapixel Ethernet camera, arms with six-axis force-torque sensors at the wrist, force controlled grippers, and an omnidirectional mobile base. If the standard features don't fit your needs, Meka offers various upgrades, including four-fingered hands and humanoid heads, complete with expressive eyelids (à la Meka's Dreamer), ears, and additional sensor compatibility. These add-ons will of course cost you, but we think its worth it to have those big translucent eyes staring back at you. A rather touching demo after the jump.
Kinect Hacks: Doodle Synthesizer
Clearly tired of waiting for Lionhead to put its Milo wizardry to good use, Kinect hacker "roboczar" created an application that turns a plain ol' piece of printer paper into a synthesizer by recognizing shapes drawn on the page as sound buttons. The Kinect sensor scans the object (paper, in this case) and virtualizes it into a musical instrument. What happens next, however, is where things get really magical. Roboczar uses the application -- one he wrote at MIT, applied in tandem with other open-source code -- to play a dedication to our favorite L.A. cop, Axel Foley. Bravo, sir! Head past the break and get your boogie on.
DIY telepresence robot uses PrimeSense Kinect drivers for extremely awkward push-ups (video)
From enhancing your WoW game to putting you in Tom Hanks's shoes, DIYers the world o'er really do seem to love Kinect. And what do we have here? Taylor Veltrop's Veltrobot remote telepresence 'bot uses the PrimeSense open source Kinect drivers for tracking the user's skeleton, with a modified Kondo KHR-1HV mirroring the operator's movements (which are received via 802.11n WiFi). Right now he is only controlling the arms, but with any luck we should be seeing complete control over all the robot's movements soon enough. Once the thing is finalized, Veltrop plans on releasing an open source development kit. And then? That's right: robot avatars for everyone!
PrimeSense's OpenNI provides the best Kinect drivers yet, from someone who would know
We've been so wrapped up in Kinect hacks lately that we actually missed a Kinect non-hack that emerged last week. PrimeSense, who built the initial Project Natal reference hardware for Microsoft, has released its own open source drivers for the Kinect. PrimeSense is working with Willow Garage (best known for its open source ROS robot operating system), and Side-Kick (a motion gaming startup) through a new OpenNI organization it set up, and the trio will be combining their powers for good. The OpenNI framework will cover low-level hardware support (drivers for actual cameras and other sensors), and high-level visual tracking (turning your body into a 3D avatar that kicks ass in a virtual world). This should be a boon to an already vibrant Kinect hacking community, and if the video above is any indication, we aren't far from Kinect-level interaction and gameplay on our lowly PCs. [Thanks to everyone who sent this in]
Kinect sensor bolted to an iRobot Create, starts looking for trouble
While there have already been a lot of great proof-of-concepts for the Kinect, what we're really excited for are the actual applications that will come from it. On the top of our list? Robots. The Personal Robots Group at MIT has put a battery-powered Kinect sensor on top of the iRobot Create platform, and is beaming the camera and depth sensor data to a remote computer for processing into a 3D map -- which in turn can be used for navigation by the bot. They're also using the data for human recognition, which allows for controlling the bot using natural gestures. Looking to do something similar with your own robot? Well, the ROS folks have a Kinect driver in the works that will presumably allow you to feed all that great Kinect data into ROS's already impressive libraries for machine vision. Tie in the Kinect's multi-array microphones, accelerometer, and tilt motor and you've got a highly aware, semi-anthropomorphic "three-eyed" robot just waiting to happen. We hope it will be friends with us. Video of the ROS experimentation is after the break.
Willow Garage now selling the PR2 for $400k a pop
While it was fun while it lasted, it was obvious that Willow Garage couldn't keep giving away its ultra-high-end development platform PR2 bots forever. After shipping 11 of the bots to research institutes, Willow Garage is now selling the PR2 to all comers -- as long as they've got 400 grand in their back pocket. We've covered the specs before (oodles of CPU power, two highly articulated pincer arms, and high-end vision systems), along with some of PR2's recent hijinks, and hopefully we see more of that sort of stuff now that the rugged, ready-for-adventure PR2 is on the market. If you can't scrap together all the cash, Willow Garage will also be offering a discount $280k version to people and institutions that can demonstrate "past performance and leadership" in open source robotics software -- a topic obviously near and dear to Willow Garage's heart with ROS, the OS that powers PR2 and is slowly spreading throughout much of the world of higher-end personal robotics. As for the high price and its generally opaque business model, Willow Garage compares the current state of its industry to high end workstations in the 70s, back when researchers were spending more money and time figuring out what their computers could do than actually accomplishing anything with them. Willow Garage isn't planning on making any sort of killing in the business yet -- they'd just be happy to have the PR2 project at a self sustaining level -- but they're working toward what they see as the "next radical shift" in productivity, a personal robotics follow-up to the personal computer revolution. This is a future similar to the one Bill Gates was talking up back in 2006, but of course Willow Garage wants its open source ROS platform to be the "Microsoft" this time around. They certainly don't plan to corner the hardware market in the process, however: the company hopes the quasi-followup to the PR2 will actually be built by multiple companies. %Gallery-101640%
Open source Qbo bot makes the jump to ROS, the open source robot OS
var digg_url = 'http://digg.com/programming/Open_source_Qbo_bot_makes_the_jump_to_ROS'; While the Willow Garage-initiated ROS is designed to consolidate and accelerate robotics innovation for the long term, it's still a long ways from powering your robotic butler / life coach / best friend, so it's exciting to see it put to use in the here and now. The folks at Thecorpora, responsible for the Qbo open source robot project, have been busy converting Qbo's original Java API into ROS, and just announced they're at 99.9 percent completion of that task. That means the Qbo gets instant access to some of the fun development going on in ROS, like stacking all its cameras and ultrasonic sensors into a system for machine vision, or controlling the bot with a Wiimote or a PS3 controller. (There's a video after the break of the Wiimote in action). Don't think Qbo will be powerful enough for you? Willow Garage just announced that it's about to put its own ROS-powered PR2 bot on sale soon, after a few months of its (highly successful) PR2 Beta Program.
Willow Garage PR2 robot plays pool, gives Fast Eddie a run for his money (video)
We're pretty big fans of Willow Garage, and its generous support of the open source Robot Operating System (ROS). For its latest trick, the company has developed a system to teach its PR3 robot billiards. Unlike projects we've seen in the past, Poolshark doesn't rely on overhead cameras to calculate moves. Rather, it's forced to conform to standard rules: it can only shoot from where the cue ball lay, and it sights shots from the same vantage point as human player would. And, you know what? While not perfect, the robot does pretty well. Not bad for a week's work, eh? Video after the break.
Willow Garage starts shipping its PR2 Beta Program bots: get ready for ROS-powered hijinks
It isn't hard to get behind a company like Willow Garage, who not only has enough funding to invest heavily in building on ROS, an open source Robotics Operating System that's gaining traction in the robotics community, but also managed to dig up enough spare change to give away $4.4 million in robots to a few lucky research institutions. There were 11 schools selected to receive the Willow Garage-developed PR2 Beta, which stuffs some very high end sensors, two articulated arms, and sixteen CPU cores on top of a rolling base -- providing a lot of leg room for advanced functionality. Of course, in the world of robots, "advanced" means stuff like opening doors and not running over your cat, but with a common code base to work from and all this fancy hardware, hopefully these schools will manage to push the industry along a bit during the next two years that the PR2 Beta Program lasts.
ROS: a common OS to streamline robotic engineering
The biannual International Joint Conference on Artificial Intelligence has this year shed light on a new effort to standardize robot instructions around a common platform, so that designers won't have to "reinvent the wheel over and over" with every project. Presently, robot design is undertaken in an ad hoc fashion, with both hardware and software being built from scratch, but teams at Stanford, MIT and the Technical University of Munich are hoping to change that with the Robot Operating System, or ROS. This new OS would have to compete with Microsoft's robotics offering, but the general enthusiasm for it at the conference suggests a bright future, with some brave souls even envisioning a robot app store somewhere down the line. Video after the break.
Shifting Perspectives: The Druid of 2008
Every Tuesday, Shifting Perspectives explores issues affecting Druids and those who group with them. This week, our author is completely spaced out on cold medication, and is somewhat concerned that her raid performance has improved under the circumstances.The time has come (the Allie said)To talk of many things.Of Roots and Bash and Travel Form,And Strength (which scales with Kings).Why Tauren cat form sucks so hard,And whether trees have wings!And, yes, before anyone asks, I'm tripping on too much cough syrup and ibuprofen after receiving a belated viral Christmas gift from a relative. So I'll just put this out there right now; this column's probably on the weird side. I took a long look at all three Druid specs over 2008 and saw a few sad things, a few happy things, a little song, a little dance, a little seltzer down your pants, and now I'm channeling the famous Mary Tyler Moore episode "Chuckles Bites the Dust," and that has to stop because I do not believe Mary Tyler Moore ever played a Druid.If you're completely uninterested in reading an account of any spec that's not your own -- although that would make me weep into my little cup of generic label cough syrup -- here's a set of quick links to each: Balance Feral Resto
Tank Talk: The irresistible fight
Tank Talk is WoW Insider's raid-tanking column, promising you an exciting and educational look at the world of getting the stuffing thrashed out of you in a 10- or 25-man raid. The column will be rotated amongst Matthew Rossi (Warrior/Paladin), Adam Holisky (Warrior), Michael Gray (Paladin), and Allison Robert (Druid). Our aim is to use this column to debate and discuss class differences, raid-tanking strategies, tips, tricks, and news concerning all things meatshieldish. Since Tank Talk began, we've gotten a few questions from people about raid fights that require tanks to use resist gear. With all of Burning Crusade's raid attunements now removed, and with lots of guilds testing the waters in Tier 5 and Tier 6 before Wrath hits, I figure now's as good a time as any to discuss what resist sets you're going to want if your guild is intent on progression. The resist gear issue is nowhere near as dire as it was in vanilla WoW (Molten Core, anyone?) and in general the raid as a whole rarely needs to worry.Tanks are special. But you knew that already, didn't you?This guide covers all of the existing 10-man and 25-man content in the game outside of Sunwell Plateau:
Ready Check: Reliquary of Souls
Ready Check is a weekly column focusing on successful raiding for the serious raider. Hardcore or casual, ZA or Sunwell Plateau, everyone can get in on the action and down some bosses. Even if they are mysteriously conglomerate faces...Continuing our jaunt through Black Temple, this week's Ready Check looks at the Reliquary of Souls, also known as the Essence of Souls (RoS or EoS for short). How often is it you get to fight three oversized faces joined together? Savour this opportunity now...You'll encounter RoS by making your way through Black Temple, usually after either Teron Gorefiend or Gurtogg Bloodboil, depending on how your guild prefers to do things. Let's take a look at the fight.
Raid Rx: Raiding meets Patch 2.4
Raid Rx is designed to encapsulate and cure the shock and horror that is 25-man raid healing. Ok, so it's mostly horror... Anyways, if you're a big fan of X-TREME Whack-A-Mole (or are being forced into it against your will) this is the column for you. I need a T-Shirt that says "I came, I saw, I forgot to stand inside the circle and got locked out of the Kale Fight." /bonk So some of my diehard fans (hi mom!) might notice that this week I've deviated from my normal Tuesday posting to bring you all the latest healer gossip... err... tips from the newest 25-man raid scene. My goal is to do a compilation of all the major raiding changes reported since the patch went live. After that I'll get into the things I learned the hard way last night on Kalecgos. Join me after the break!
