A four-wheeled robot cart is driving around Antarctica helping scientists study ice by avoiding crevasse dangers. Dubbed Yeti, the robot uses GPS and can map an area to inform researchers where the cracks and crevasses are located. Wonder if Yeti could detect the Atlas Fracture?

Dr. Crandee and Dr. Nouri certainly would have liked to have a Yeti robot while the terrorist team was descending the crevasse-scared glacier onto the Ross Ice Shelf. Certainly Josmen probably wished they had one!
