Abstract
Provided is a transportation device for loading a cargo and moving in a moving direction, comprising: a bed for loading a cargo thereon; four leg parts for being able to receive a part of a weight of the bed individually; a movable part for moving the leg parts individually to change relative positions with respect to the bed individually; and a control part for controlling the movable part for the four leg parts individually, wherein the control part is for changing the relative position of at least one of the four leg parts with respect to the bed within a range in which a center of gravity of the bed is located inside a profile of a horizontal triangle made by three leg parts among the four leg parts as apexes, causing the three leg parts to support the bed and releasing one remaining leg part from supporting the bed.
Claims17
A transportation device for loading a cargo and moving in a moving direction, comprising:
- a bed configured to load a cargo thereon;
- four leg parts configured to be able to receive a part of a weight of the bed individually;
- a movable part configured to move the leg parts individually to change relative positions with respect to the bed individually;
- a control part configured to control the movable part for the four leg parts individually;
- and
- a pair of rail members configured to be slidable with respect to the bed in the moving direction of the bed,
- wherein the control part is configured to change the relative position of at least one of the four leg parts with respect to the bed to within a range in which a center of gravity of the bed is located inside a profile of a horizontal triangle made by three leg parts among the four leg parts as apexes, causing the three leg parts to support the bed and releasing another one leg part from supporting the bed, and
- wherein the four leg parts are coupled slidingly with respect to the pair of rail members in an extending direction of the pair of rail members and configured to support the bed via the pair of rail members.
