Patent ID: 8565982

Claim:
A transportation apparatus ( 1 ), said apparatus comprising: a payload receiving unit ( 30 ), a transportation body ( 10 ), and a controllable compensation system ( 20 ) arranged there between and devised to allow adjustment of a desired spatial relationship between a payload surface ( 250 ) of said compensation system ( 20 ) for attachment of said payload receiving unit ( 30 ) and a transportation surface ( 150 ) of said transportation body ( 10 ), wherein said compensation system ( 20 ) comprises at least a first compensation unit ( 210 ) and a second compensation unit ( 230 ) arranged for adjustment of said spatial relationship, wherein said first compensation unit ( 210 ) is arranged for adjustment of said spatial relationship in a first direction and said second compensation unit is arranged for adjustment of said spatial relationship in a second direction different from said first direction, whereby said compensation system ( 20 ) is adapted to maintain a desired orientation of said payload surface ( 250 ) independent of changes of orientation of said transportation surface ( 150 ) of said transportation apparatus ( 1 ), wherein said compensation system ( 20 ) is adapted to maintain a common point of gravity of said transportation apparatus ( 1 ) including a payload by displacing a center of gravity of said payload receiving unit ( 30 ) and said payload opposite to a displacement of a center of gravity of said transportation apparatus ( 1 ), and wherein at least one of said first and/or second compensation units are extendable from at least one end of the first and/or second compensation units during operation.
