Robot Yeti Tells You Where Not to Go in Antarctica

Mar 12, 2013   |   by Evan Ackerman   |   IEEE Spectrum

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.
