A multi-purpose planet planetary exploration rover is provided in this invention, which relates to the field of planet exploration. The multi-purpose planetary exploration rover includes a case body, mounted with a first wheel at left and right sides respectively; and a cantilever, having a front end connected to the case body, a rear end of the cantilever being mounted with a second wheel; wherein the cantilever is rotated or fixed relative to the case body, the second wheel is steered relative to the cantilever, and the first wheel and the second wheel are used to drive the multi-purpose planetary exploration rover. Compared with the prior art, the multi-purpose planetary exploration rover of this invention can effectively explore special geographic locations such as cliffs, volcanic craters, craters and lava caves on alien planets.

A road milling machine includes a rear wheel or track mounted on a pivot arm such that the wheel or track is movable between a first outer end position projecting laterally relative to the machine frame, and a second inner end position which permits milling close to an edge. A travel drive of the rear wheel or track provides a driving force to move the wheel or track between the end positions.
