Abstract
An all-terrain rover has a ladder frame having one or more crosspieces, two drive units connected on opposite sides of the frame, first and second auger cylinders engaged with the drive. The drive units are in contact with the axes of the auger cylinders and the flange of the first cylinder is wound in an opposite direction to the flange of the second cylinder. The cylinders are counter-rotated to urge the rover forward. Sampling equipment is mounted on the frame. In an embodiment, each cylinder further comprises a conical end cap at each end. Each cylinder may have a frustaconical end cap at each end, and each cylinder may be buoyant.
