We know very little about the surfaces of the Moon and Mars
Some areas may be covered with a large layer of sand, dust or soft soil.
Outstanding science fiction writer Arthur C. Clarke in the novel “A Fall of Moondust”...
...An all-terrain vehicle that moves with the help of rotating augers.
Has the ability to lift the module directly from the surface.
While moving, the all-terrain vehicle follows the surface topography, so the module itself and everything inside it must be securely secured against displacement.
The augers rotate in different directions; if the augers rotate in one direction, the all-terrain vehicle will move sideways. At different speeds of rotation of the augers, the all-terrain vehicle will turn. The screws are located in parallel planes. Each auger is mounted on two levers that allow it to move in a vertical plane and change the angle (+/- 5 degrees) relative to the horizontal plane. This allows the augers to be better adapted to the terrain. The drive for the levers on each side is active from one gear motor.
A special feature of the screw propulsion system is the requirement for very high drive power. Onboard nuclear reactor - too serious :)
Using auger volumes as tanks for hydrogen and oxygen is too dangerous :(
You can take electricity from stationary sources at the start and finish points. For this purpose, the all-terrain vehicle has 2 coils. Each one holds 2.5 km of electrical cable. In the middle of the journey from the rear reel, the cable will be unwound and lie along the traversed path. The robot or accompanying person will disconnect the rear cable and connect the cable from the finish to the front coil. The rover will move along the lying cable and wind it onto the front reel. The same procedure will apply when moving in the opposite direction.
Model for illustration only
Everything is very simple. If you have any questions I will try to answer
