NIH Funds UMB Brain Surgery Robot

Posted 15 Nov 2012 at 19:34 UTC by steve

According to a University of Maryland news release the National Institutes of Health (NIH) has awarded a $2 million grant to UMD and UMB to further their development of a tiny surgical robot that would assist neurosurgeons in the removal of hard to reach brain tumors. The robot is known as the Minimally Invasive Neurosurgical Intracranial Robot (MINIR) and has been under development at the Robotics Automation & Medical System Laboratory for a number of years. The MINIR Prototype has been tested while under continuous magnetic resonance imaging. The grant will allow the development of a second-generation prototype, MINIR-II. From the MINIR website:

"We envision MINIR to be under the direct control of a human operator, with targeting information obtained exclusively from frequently-updated MRI. MINIR will be fully MRI compatible, so that frequently-updated MRI can be used to provide virtual visualization of the target by the human operator as the target's 3-dimensional shape changes during tumor removal."

As seen in the rendering above, the MINIR robot will fit inside the MRI scanner with the patient, allowing surgery to be done while the patient remains in the MRI machine. For all the details, you can check out the paper, "Toward a Meso-Scale SMA-Actuated MRI-Compatible Neurosurgical Robot" (PDF format). Other papers about the MINIR robot may be found on the MINIR project webpage. Read on to see photos and video of the earliest MINIR prototype in action.

OLinuXino Nano-ITX Open Hardware SBC

Posted 14 Nov 2012 at 17:03 UTC by steve

Move over, Raspberry Pi, there's another open hardware single board computer (SBC) out to win your hearts and minds. The weirdly named Olimex OLinuXino is making the news today on PCWorld, Slashdot, and FreeIO. The OLinuXino sounds like it might be Xenu's computer of choice. But in reality, it's a Nano-ITX with a 1 GHz ARM A13 Cortex A8 CPU with 3D Mali400 GPU. No word yet on whether there's source for the Mali400 GPU driver but a free software driver project called Lima exists. The board has 512MB of RAM, VGA out, SD slot, USB, audio in/out, a Real time clock, a UEXT connector that supports modules with Zigbee and bluetooth. It also has some GPIO pins, 3 I2C, 2 UARTs. Like many ARM SBCs, it lacks any A/D or D/A, which may be problematic for robotics users. But with the addition of an Arduino to handle I/O, this might make an interesting robotics controller. The board can run a variety of GNU/Linux distros like debian and can also run the Linux-based Android distro used on most mobile devices. Cost for all this open hardware goodness? About $57 USD.

DARPA Working on Sub-stalking Robots

Posted 13 Nov 2012 at 17:33 UTC by steve

A DARPA program is developing autonomous underwater robots that will stalk submarines and continuously report their location and movements. In particular, these robots will look for the quiet diesel submarines that are becoming more common and perceived as a threat to both military and civilian maritime activity. Russian and France are selling these inexpensive ($200-$300 million) submarines like crazy to anyone who wants them and at least 40 nations now own and operate them including tiny countries like Venezuela. From DARPA's news release, program manager Scott Littlefield says:

“Key features and technology for the vessel include advanced software, robust autonomy for safe operations in accordance with maritime laws, and innovative sensors to continuously track the quietest of submarine targets. Our goal is to transition an operational game-changer to the Navy. This should create an asymmetry to our advantage, negating a challenging submarine threat at one-tenth their cost of building subs."

DAPRA calls the robots Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessels (ACTUV). In August DARPA awarded a $58 million, 3 year contract to Science Applications International Corporation (SAIC). Yesterday, CMU NREC announced they'd been selected as part of a team assembled by SAIC to build and test the ACTUV robot.

Reasoning Without Language

Posted 12 Nov 2012 at 17:33 UTC by steve

An interesting 2009 paper by Ronaldo Vigo and Colin Allen has been released online, titled How to reason without words: inference as categorization (PDF format). The paper takes on the common idea that reasoning is a singularly human activity that relies on our language-based conception of inference. The alternative model of reasoning presented in the paper could apply to nonhuman animals as well as to robots. From the introduction:

We describe an alternative framework that is capable of providing a unified approach to reasoning and the subsymbolic perceptual processes underlying similarity assessment, discrimination, and categorization. The framework is provided by the modal similarity theory (MST) of Vigo (2008), which we describe in ‘‘Modal similarity theory’’.

The paper looks at similarities and differences between the reasoning abilities of animals such as dogs and young human children. It then attempt to build a plausible case for how inference could be accomplished without language. An experiment involving similarity assessment of iconic images is described. A connection is drawn between similarity assessment and boolean operators. Finally they propose that reasoning is based on more fundamental, non-linguistic processes that include discrimination, categorization, and similarity assessment.

Random Robot Roundup

Posted 10 Nov 2012 at 02:27 UTC (updated 10 Nov 2012 at 16:13 UTC) by steve

Purdue University received a $6 million grant to develop an autonomous agricultural robot capable of pruning grape vineyards and apple orchards. Let's hope the Purdue robot puts up a fence around the orchard to keep out the Robo-squirrels being developed at the University of California. UC is also advancing the state of the art in split-brain research. Other brain research this week includes an MIT study of what actually happens when the brain passes from consciousness to unconsciousness. A better understanding of the human brain may help researchers finally get artificial intelligence right - Noam Chomsky says they've been getting it wrong all this time. Poly Bug sent us a link to CIROS, a Korean humanoid robot who slices cucumbers and tosses salads. Franke Tobe of the Robot Report let us know about a new article he's posted about Eldercare Robots. And The Swirling Brain spotted an article describing a new method proposed by physicists that may finally settle the question of whether or not our reality is just a computer simulation.

Free Your Mind: The Return of FreeIO.org

Posted 9 Nov 2012 at 01:13 UTC by steve

Long-time readers will remember in the early 2000s we had frequent stories of open hardware board designs from a website called FreeIO.org. The FreeIO.org project was started by Diehl Martin, better known as Marty. He named all his boards after breakfast foods, which gave us the opportunity to write fun headlines like "Hot Grits for your Robot". Other boards were called Donut, Toast, Cornbread, Biscuit, Juice, and Flapjack. Schematics, CPLD source, CAD files, Gerber files, were all released under the GNU GPL. Marty's designs were also raised as an example when Jim Turley wrote his famously wrong prediction in 2002 that open source hardware would never become widespread. But in 2004, things slowed down when Marty announced he'd been diagnosed with pancreatic cancer. He continued to work on new boards until he posted his farewell message in 2006. Marty passed away in October of 2007. After that, the FreeIO.org project ground to a halt for a few years. But today, the FreeIO.org website was relaunched! From the announcement:

"The time has come to get things rolling again and I’m starting with a relaunch of the website. Marty’s free hardware designs are still here and hopefully we’ll find volunteers to work on new hardware projects to add. I’ll also start updating the resource pages to make them more useful again. Meanwhile, I’ve decided to make the site more immediately useful by aggregating all the free hardware and open hardware news, so members of the open hardware community can have one central place to find out what’s going on."

We're not sure where the website is headed in the future but we're glad to see FreeIO.org back online and look forward to using them as a reliable open hardware news source. They're already posting news updates from the major open hardware and free hardware organizations such as the Open Source Hardware User Group, the Open Source Hardware Association, and the Open Source Hardware and Design Alliance. Who knows, if we're lucky, maybe we can drum up support for an open source robot controller board!

Robots Reduce Cost of Science for USGS

Posted 7 Nov 2012 at 17:18 UTC (updated 7 Nov 2012 at 17:36 UTC) by steve

After a contentious election, the US Government will be returning to business as usual soon and one thing both sides agree on is that the cost of government needs to be reduced. A recent report by the US Geological Survey illustrates how robots are helping out with this problem. Airborne scientific observation missions can cost as much as $30,000 per hour. The USGS is replacing these expensive airborne data gathering missions with remotely piloted vehicles, or drones, which can complete an entire mission for $3,000. So far the USGS is using the Honeywell T-Hawk Micro Air Vehicle (MAV) and AeroVironment Raven RQ-11B. The Raven in particular has other advantages over manned missions besides cost. From the report:

The initial USGS mission in March 2011 studied the annual north-south migration of endangered sandhill cranes from Arizona through Colorado to Montana and Wyoming. The cranes fly north in the first part of February and spend much of each spring in Colorado’s San Luis Valley at the Monte Vista National Wildlife Refuge. Thermal cameras capturing images of the cranes at roost were used to determine population trends in collaboration with the FWS. “Because the Raven is small and quiet, it could fly low enough – 75 feet – to photograph the birds without disturbing them. Moreover, the mission cost only one-tenth of a conventional airborne survey"

Having proved that using robotic aircraft can dramatically reduce costs, the USGS is looking for other missions that can take advantage of the drones. They'll soon be replacing conventional aircraft in climate change studies, geophysical fault and fracture mapping missions, and other tasks. The USGS will team with NASA Ames Research Center to use the SIERRA UAS. They also hope to increase the autonomy of the planes, further reducing the need for expensive human interaction. Read on to see photos and video of the USGS drones in action.

Help Give Wings to RoboBrrd and STEM

Posted 5 Nov 2012 at 17:40 UTC (updated 5 Nov 2012 at 17:40 UTC) by steve

Remember back in 2008, when we helped send RobotGrrl to Stanford's EPGY AI program by buying Styrobots? If you've followed her progress since then, you probably know that she went on to become the host of the eccentrically entertaining Robot Party, a weekly podcast/Google Hangout about robots. She's also been busy developing an educational robot called RoboBrrd.

"We have shown RoboBrrd at various Maker Faires, and kids are instantly attracted to its soft and friendly appearance. They observe how it works, ask questions about how it functions, and they can envision themselves building one. The hands-on learning experience of building RoboBrrd is important to establish problem solving skills that can help in future robotic projects and STEM related studies. RoboBrrd is a great project to bridge the real-world lessons to the theoretical side."

This is where you come in - RoboBrrd is ready to go into production as a kit and you can help RoboGrrl and STEM education by contributing to the RoboBrrd Indiegogo campaign. The money will go towards manufacturing RoboBrrd kits. The design is completely Open Source hardware and software You can check out the RoboBrrd Instructable if you'd like to build your own using popsicle sticks and an Arduino! Read on to see some video of RoboBrrds in action!
