Robot Yeti Tells You Where Not to Go in Antarctica
March 7, 2013
Antarctica looks all nice and smooth, but lurking beneath the snow are the gaping maws of crevasses of doom. Doom, I say! And it's not just me saying it: the threat of crevasses means that moving anything from one place to another on the ground is a slow, potentially deadly process. That's why some researchers from Dartmouth [including professor of engineering Laura Ray and her students] came up with Yeti, a GPS-guided robot that can drag a ground-penetrating radar around to detect impending doom. This robot has been around for several years now, but its masters have just published a paper in the current issue of the Journal of Field Robotics, showing that Yeti can make a huge difference in polar logistics.
