To provide high rough terrain overrunning ability running the whole distance of an rough terrain environment in severe irregularity of the lunar surface or the like, and make self recovering and running contorting possible regardless of shape of the grounding surface and a tumble condition at tumbling/ lateral turning time.
A diameter D3 of central wheels 4a, set up in a main unit part 6, is formed larger than a vertical direction thickness H2 of the main unit part 6, the other wheels 4 are set up through an articulated link mechanism comprising an upper link 5a, lower 5b and articulations 7, 8 so as to improve rough terrain overrunning ability. It is capable of running even in a back condition at tumbling time by setting the central wheel 4a to be matched with a vertical direction center line 33 of the main part 6 into vertical symmetry, and an and of self recovering at tumbling time. by providing an articulated manipulator set up in the main unit part 6.
