Tiny flying robots! Meet the quadrotor

"Tiny Flying Robots!  Meet the Quadrotor"

A May 1, 2013 CNN article, "Tiny Flying Robots! Meet the Quadrotor," covers the work of Vijay Kumar, faculty at University of Pennsylvania and TerraSwarm Researcher.  The article discusses the efforts of Kumar and others at the General Robotics, Automation, Sensing and Perception Lab concerning using quadrotors in Japan after the 2011 earthquake.  The idea was to use quadrotor aircraft to map the interior of unstable buildings.  Kumar is quoted as stating "We went into a collapsed building; we mapped three floors. We got three-dimensional maps, and we were able to show that this sort of thing is feasible today."
