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.
