You may not be able to control it with your mind, but this robotic wheelchair from Sweden's Luleå University of Technology can still offer something that only a few others can -- "sight." The chair uses a laser sensor to generate a 3D map of its surroundings, which is then transferred to an on-board haptic robot, allowing the bot to pick up on and navigate its way around any obstacles. A visually impaired student already took the contraption out for a spin and said he felt "safe" while traveling through crowded corridors, comparing the experience to "using a white cane." Luleå's engineers, however, still have some fine tuning to do. The laser, for instance, can only recognize objects at a specific height, while ignoring everything above or below its field of vision. Researchers are also busy developing a new 3D camera for the chair and are hoping to have it ready for commercial use within the next five years. There's a full PR waiting for you a...

Assuming you own a Sensefly Swinglet CAM or some other high-res camera-equipped UAV, you could be just minutes away from turning your plain old 2D aerial photos into comprehensive 3D maps. Pix4D, a new software program coming out of EPFL -- the same institute that brought us this race of altruistic robots -- takes images shot using an aerial drone to render 3D maps in the cloud in just 30 minutes. Users upload images taken with their flying machines, at which point Pix4D kicks into action, defining high contrast points in the phots and pasting them together based on those points. It then renders a 3D model, overlays the graphics, and spits out a Google Earth-style map. So what's with this 4D business? Well, its developers claim that users can easily see the progression of any model by deploying their Sensefly drone whenever they see fit, throwing the added layer of time into the mix. You can see the fruits of Pix4D's labor in the video after the break. ...
