Abstract: A lunar rover chassis includes at least two wheels, a power supply, and at least one axle assembly coupled between the at least two wheels. The axle assembly includes an inner axle coupled with the at least two wheels, and an outer wall surrounding the inner axle. The inner axle is configured to rotate to drive rotation of the at least two wheels, the inner axle includes a first conductive surface, and the outer wall includes a second conductive surface. The power supply is electrically connected to the first conductive surface of the inner axle and the second conductive surface of the outer wall, and the power supply is configured to apply a voltage difference between the first conductive surface of the inner axle and the second conductive surface of the outer wall to attract or repel lunar regolith from the outer wall.
