Made of a pair of two-wheeled vehicles, NASA's DuAxel is designed to descend crater sides and near-vertical cliffs on the Moon, Mars, and beyond.
A rover trundles over rocky terrain, its four metal wheels clattering along until they encounter a seemingly insurmountable hazard: a steep slope. Down below is a potential trove of science targets. With a typical rover, the operators would need to find another target, but this is DuAxel, a robot built for situations exactly like this.
