Hokies give (tactile) sight to the blind so they can drive, no word on turning water into wine
Daytona International Speedway is synonymous with speed, auto racing, and . . . blind people? Virginia Tech's Robotics and Mechanisms Laboratory (RoMeLa), along with the National Federation of the Blind (NFB), recently debuted its sight-optional and street-legal SUV at the famed racetrack. Dr. Dennis Hong and his students first let blind folks drive a dune buggy without the help of a sighted copilot in 2009 -- as a first step to achieving the goal of a street-legal SUV for the sightless crowd. The SUV in question was designed for the NFB's Blind Driver Challenge, and is equipped with a drive-by-wire system -- also seen in the RoMeLa autonomous vehicle -- that was modified for use with RoMeLa's SpeedStrip and DriveGrip tactile interface technology. It works by using a laser rangefinder to map the surrounding area, relaying information for acceleration and braking to the driver by rumbling the SpeedStrip seat, and passing along turning info through vibrations in the DriveGrip gloves. The system was not developed solely for the purpose of getting blind drivers on the road, however, as Virginia Tech suggests that its technology could also be used in gaming applications. We're not quite ready to see blind drivers on actual roads just yet, but why shouldn't our sight-impaired friends get to enjoy Gran Turismo 5 with the rest of us? Video's after the break.
Open source DARwIn-OP bot can be yours for just $12,000
A few weeks back we caught our first glimpse of the open source, modular DARwIn-OP developed at Virginia Tech's Robotics and Mechanisms Laboratory, also known as RoMeLa. Well, there's more information available now about the upcoming little bot, so here's what we know. Korean company Robotis is making available the bot's open source software, schematics, CAD and fabrication manuals, in addition to selling the fully assembled robots. DARwin-OP was unveiled recently at the IEEE-RAS International Conference on Humanoid Robots, and is built on a 1.6GHz Intel Atom Z530-based FitPC2i which boasts a 4GB SSD, 2GB of DDR2 RAM, 802.11n WiFi. Shipments of the 17.9-inch tall humanoid robots are being sent to universities first at a price of $9,600, and will run $12,000 at full retail. Hit up the source links for a far more detailed look at DARwin-OP's specs, and there's a video after the break.
DARwIn-OP humanoid revealed, ready to open source your robotics program
The next version of the RoboCup-famous DARwIn bot is about ready to give the Nao a run for its money. The new DARwIn-OP from Robotis and Virginia Tech's RoMeLa (led by Dr. Dennis Hong, who joined us on the Engadget Show earlier this year) is just about to land, and the first pictures of the finished thing have started to circulate. While the bot is designed to perform, with sensors and servos suitable for higher-end robotics, the main thrust of the design is the open source and modular nature of the hardware and software. The bot can be purchased as a product from Robotis, but the CAD files are publicly available, and its plastic parts can be fabricated by the end user to save money (you do have a 3D printer, right?). Rumor has it the robot will retail for around $8,000, around half the cost of its closed source Nao competition. The full unveil of the robot is due at the IEEE-RAS International Conference on Humanoid Robots a couple weeks from now.
RoboCup Soccer 2010 finals show impressive realism by feigning injuries (video)
The World Cup may still be ongoing (despite what the US, England, and a handful of others may think), but the RoboCup 2010 in Singapore has just closed shop with an edge-of-your-seat display of autonomous action. The final game came down to two German teams, the Darmstadt Dribblers and the FUmanoids. As seen at numerous points, both android teams have even learned the ancient art of diving, toeing the uncanny valley a little to close for comfort. Video after the break -- we won't to spoil the ending, so let's just say Germany won by a sizable margin. If fierce competition isn't your cup of tea, we've also got footage of DARwIn-LC, a low cost (hence the name) humanoid from our friends at Virginia Tech's RoMeLa. These adorable little guys cost about $2,500 apiece and will be going out to 11 of VT's partner universities. Update: Dr. Dennis Hong himself sent us a few clarifications. The DARwIn-LC is a collaboration between RoMeLa and the company Robotis. No price has been disclosed, but the $2,500 is incorrect. Additionally, the robot is being planned as a "true 'open platform.'" In Hong's words, "we are "planning" to post all CAD drawings, fabrication and assembly manuals, and also the basic software on-line for free. Thus any one with certain equipment, budget, and skills will be able to make one them selves - or purchase the entire thing or parts from Robotis. We want to form a community of DARwIn-LC users to share new ideas for improvement, hack it, etc. and use the robot for research, education, outreach, and of course, an easy entry point for the RoboCup humanoid division."

Virginia Tech researchers reveal full-sized CHARLI-L humanoid robot (update: video!)
Dr. Dennis Hong was kind enough to give us a glimpse the CHARLI robot on The Engadget Show this weekend -- or its leg, anyway -- but he and his students have just now finally revealed the full-sized bot that's been described as a "robot teenager." As we'd heard, CHARLI is actually a series of robots that initially consists of the 5-foot tall CHARLI-L (or lightweight, pictured above), and the forthcoming CHARLI-H (or heavy), both of which are completely autonomous, with a full range of movements and gestures thanks to a series of pulleys, springs, carbon fiber rods, and actuators (not to mention some slightly more mysterious AI). What's more, while CHARLI-L is currently restricted to walking on flat surfaces, CHARLI-H promises to be able to walk on the uneven ground around the Virginia Tech campus, and eventually even be able to "run, jump, kick, open doors, pick up objects, and do just about anything a real person can do." Unfortunately, there doesn't seem to be any video of CHARLI-L in action just yet, and it is still somewhat of a work in progress -- the researchers say it will be able to speak soon, and they're also busily working to improve its soccer skills in time for this year's RoboCup. [Thanks, Kyle] Update: Video is now after the break!
Amoeba-inspired ChIMERA robot slithers on video
Virginia Tech's RoMeLa Lab has done more than its fair share to further the development of our future robot overlords. Now, in a recent TED talk, Dr. Dennis Hong brings us up to date on some of the creepier candidates for world domination, including the spider-like STRiDER and the amoeboid ChIMERA (Chemically Induced Motion Everting Robotic Amoeba). The latter achieves locomotion by the movement of its silicone skin, squeezes through spaces half its diameter, and travels up to half a meter per second. The good doctor is tight-lipped on much of the device's specifics, but among options being explored for powering the thing are chemical actuation, electroactive polymers, and air-driven tubes. Check out the team's work in the video after the break. [Thanks, Travis]
Robotic hand controlled by compressed air grasps the concept of delicacy
The Robotics and Mechanisms Laboratory (AKA the RoMeLa Project) at the College of Engineering at Virginia Tech has designed and built a prototype robotic hand that is controlled and operated by compressed air. Called RAPHaEL (Robotic Air Powered Hand with Elastic Ligaments), the robot can hold heavier, solid objects, as well as light or delicate ones such as a light bulb or an egg. The hand is powered by a compressor air tank at 60 psi and an accordion style tube actuator, with microcontroller commands operating and coordinating the movements of its fingers. It uses no other motors, and the strength of the grasp is controlled by a change in air pressure, making the hand quite dextrous. RAPHaEL -- which is part of a larger RoMeLa robot project named CHARLI -- has already won several awards, including grabbing first prize at the 2008-2009 Compressed Air and Gas Institute Innovation Award Contest. RoMeLa researchers envision CHARLI one day roaming the VT campus making friends with students and visitors. We look forward to that day, but until then, check out RAPHaEL holding some stuff after the break.
Virginia Tech researcher crafting amoeba-inspired robotic helpers
Although we've seen failed attempts at turning amoebas into helpers, Virginia Tech's Dennis Hong is hoping that his creations will see a bit more success. Using funding from the prestigious CAREER grant, the researcher is designing a Whole Skin Locomotion (WSL) mechanism "for robots to work on much the same principle as the pseudopod, or cytoplasmic foot, of the amoeba." The device's primary goal seems to hover around the world of search-and-rescue, as the diminutive crawler can maneuver in and around tight spaces without regard for its own health, and of course, a nearly-microscopic bot just can't be developed without hinting at one day ending up somewhere inside your body. Notably, it appears that Mr. Hong isn't satisfied with just building a prototype, as he's already got plans for implementing the technology into projects such as IMPASS (Intelligent Mobility Platform with Active Spoke System, DARwin (Dynamic Anthropomorphic Robot with Intelligence), and STriDER (Self-Excited Tripedal Dynamic Experimental Robot).[Via MedGadget]
