Robotic wheelchair uses 3D imaging to 'see' for visually impaired drivers

From Engadget: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
