LIDAR-equipped robot maps dangerous areas in 3D so you don't have to
Looks like the kids at MIT might have a little competition for their LIDAR-equipped 3D mapping drone. Researchers at Missouri University of Science and Technology have teamed up with the University of Missouri-Columbia for a prototype robot that uses light detection and ranging (similar to RADAR, but with lasers) to map areas and send the 3D data to a nearby laptop. The technology not only provides detailed info on floor plans and physical structures (such as possible structural damage) but it can also "see" people inside a space. There are many possible applications for this, from spotting terrorists hiding in caves to seeing if your new internet girlfriend really looks like her profile pic, or -- and this is especially important in the modern era -- seeing if your new internet girlfriend is actually a terrorist (we wondered why she wanted that first meeting to take place in a cave). "Once you have the images, you can zoom in on objects and look at things from different angles," says Dr. Norbert Maerz, associate professor of geological engineering at Missouri S&T -- an ability that we wish we had while browsing PlentyofFish.com.
3D mapping drone fires lasers from a mile away (video)
The MIT Technology Review has unearthed a new laser-based 3D mapping robot that can produce results similar to those obtained from $100,000 systems at about a fifth of the cost. Funded by the US Army, researchers at the Stevens Institute of Technology have now demonstrated the Remotely Operated and Autonomous Mapping System (ROAMS, for short), which employs a mirror-based LIDAR system that bounces a laser off a rapidly rotating mirror and gleans environmental information from how long it takes for each pulse to bounce back. An array of video cameras and IR proximity sensors add to this recon bot's sentience, though you'll still need to be within a mile's range to operate it. So not quite yet ready for solo missions to Mars, but plenty useful for gathering data on our own planet. You'll find video and imagery of the results this machine kicks out after the break.
Radiohead's 'House of Cards' video gets 3D, interactive, and extremely trippy
Leave it to Radiohead to do something twisted, innovative, and defiantly futuristic to the art of the music video. Instead of going with underwater singing, fully animated epic, or a mysterious series of "blips," the band decided to forgo the use of cameras altogether for their latest single, House of Cards. Using 3D video acquisition systems from Geometric Informatics, and 64-element, 360-degree LIDAR from Velodyne, the band was able to create a clip that eschews traditional video recording for haunting, complex data visualizations. You can watch the video after the break, or you can get your hands dirty with a real time, interactive version you'll find by following the read link. Either way, your mind should be thoroughly blown.
Researchers show off laser-guided wheelchair that docks with vehicles
We first heard about this laser-guided wheelchair way back in 2006 but didn't really have much more than promises from the team behind it about exactly what they had in store. As New Scientist reports, however, it seems that the folks from Lehigh University and Freedom Sciences are still hard at work at it, and they're finally showing off some of their progress. The wheelchair is apparently still not entirely automated though, with it needing to be driven to the rear of the vehicle by remote control, after which the on-board LIDAR system kicks in and loads it onto the lift all by itself. Not surprisingly, the estimated price for the eventual commercial version has also gone up since we last heard from the team, with it now set to demand $30,000 (as opposed to $15,000 to $20,000) when it goes on sale later this year, assuming it gets the necessary FDA approval. Until then, you can head on over after the break to check it out in action.
NASA's PILOT project could autonomously extract oxygen from lunar soil
We've got means to extract oxygen from water, a portable bar, and even ways to deprive entire server farms of the sustenance, but a new project being tackled by Lockheed Martin is hoping to create O2 on the moon. A critical part of NASA's PILOT (Precursor In-situ Lunar Oxygen Testbed) initiative, this digger bot will work hand-in-hand with a "processing plant that will add hydrogen to moon soil, heat it to 1,652-degrees Fahrenheit, condense the steam, and finally extract the oxygen." Additionally, the blue LIDAR (Light Detection And Ranging) box atop the three-foot-long machine can assist it in locating "oxygen-rich lunar soil and autonomously carry it to a processing plant." The overriding goal is to use the newly extracted O2 for air, or moreover, to combine it with hydrogen and produce water for the four astronauts that the lunar base could support. Unfortunately, there's no timetable as to when we'll actually see the PILOT roll into action, but we're most interested in porting this bad boy over to Mars along with half the traffic in LA.[Via The Raw Feed]
