A transportation apparatus includes a payload receiving unit, a transportation body, and a compensation system arranged there between providing adjustment of a desired spatial relationship of a payload surface of the compensation unit. The compensation system has at least one of a first compensation unit and a second compensation unit for adjustment of the spatial relationship. The compensation units adjust the spatial relationship in different directions. Thus the compensation system maintains a desired orientation of the payload surface independent of changes of orientation of the transportation surface. Further, the compensation system substantially maintains a common point of gravity of the transportation apparatus including the payload by displacing the center of gravity of the payload receiving unit and the payload substantially opposite to a displacement of a center of gravity of the transportation apparatus. At least one of the compensation units are extendable from at least one end thereof during operation.
