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 units so as to be urged into rotation by the drive units, each cylinder comprising a sealed hollow cylinder; and a spiral auger flange affixed to the exterior of the cylinder, wherein the drive units are in contact with the axes of the auger cylinders are parallel and the flange of the first cylinder is wound in an opposite direction to the flange of the second cylinder, and wherein the cylinders are each counter-rotated to urge the rover forward. In one embodiment sampling equipment is mounted on the frame. In another, 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.

Claims

1. An all-terrain rover, comprising:

a. a ladder frame having one or more crosspieces;

b. two drive units connected on opposite sides of the frame;

c. first and second auger cylinders engaged with the drive units so as to be urged into rotation by the drive units, each cylinder comprising;

d. a sealed hollow cylinder; and

e. a spiral auger flange affixed to the exterior of the cylinder, wherein the drive units are in contact with the axes of the auger cylinders are parallel and the flange of the first cylinder is wound in an opposite direction to the flange of the second cylinder, and wherein the cylinders are each counter-rotated to urge the rover forward.

2. The all-terrain rover of claim 1 wherein sampling equipment is mounted on the rover.

3. The all-terrain rover of claim 1 wherein each cylinder further comprises a conical end cap at each end.

4. The all-terrain rover of claim 1 wherein each cylinder further comprises a frustaconical end cap at each end.

5. The all-terrain rover of claim 1 wherein each cylinder is buoyant.

6. The all-terrain rover of claim 1 wherein each cylinder is coated with a coating selected from the group consisting of Teflon, “

never wet”

, lard or vegetable oil.

7. The all-terrain rover of claim 1 further comprising a brush mounted adjacent to the cylinders to brush the surface as the cylinder rotates.

8. The all-terrain rover of claim 1 wherein each cylinder is rotatable in the same direction to urge the rover in a sideways direction.

9. The all-terrain rover of claim 1 wherein only one cylinder is rotatable to produce a skid turn.

10. The all-terrain rover of claim 1 further comprising a control unit connected to each of the drive units to control a rotation speed and direction of the drive units.

11. The all-terrain rover of claim 3 wherein the end cap is threaded.

12. The all-terrain rover of claim 1 further comprising third and fourth cylinders, wherein the third cylinder is adjacent and coaxial to the first cylinder, and the fourth cylinder is adjacent and coaxial to the second cylinder.

13. The all-terrain rover of claim 1 further comprising a platform across the frame.

14. The all-terrain rover of claim 2 wherein the sampling equipment comprises a valved core sampler tip connected to a descent mechanism to lower the tip into a surface below the rover.

15. The all-terrain rover of claim 2 wherein the sampling equipment comprises a cone penetrometer connected to a descent mechanism to lower the tip into a surface below the rover.

16. The all-terrain rover of claim 2, further comprising an excavator arm attached to the frame.

17. An all-terrain rover, comprising:

a. a ladder frame having one or more crosspieces, the frame having first and second sides;

b. first and second auger cylinders positioned coaxially, rotatably mounted on the first side, each cylinder comprising;

a sealed hollow cylinder; and

a spiral auger flange affixed to the exterior of the cylinder,

c. third and fourth auger cylinders positioned coaxially, rotatably mounted on the second side, each cylinder comprising;

a sealed hollow cylinder; and

a spiral auger flange affixed to the exterior of the cylinder, and

d. at least one drive unit on each side, each drive unit engaged with at least one auger cylinder on that side so as to urge the rotation of the cylinder;

wherein the axes of the first and second auger cylinders are parallel with the axes of the third and fourth auger cylinders, and the flanges of the first and second cylinders are wound in an opposite direction to the flanges of the third and fourth cylinders, and wherein the first and second cylinders are counter-rotated relative to the third and fourth cylinders to urge motion in the rover.

18. The all-terrain rover of claim 17 further comprising sampling equipment mounted to the rover, wherein the sampling equipment comprises a valved core sampler tip connected to a descent mechanism to lower the tip into a surface below the rover.

19. The all-terrain rover of claim 17 wherein each cylinder further comprises a conical end cap at each end.

20. The all-terrain rover of claim 17 wherein each cylinder is sealed and buoyant.
