Parking robot for a transportation vehicle with at least two axles and method for operating a parking robot

A parking robot for a transportation vehicle having at least two wheel axles, wherein the parking robot comprises:

• a main robot part;
• and
• a secondary robot part,
• wherein the main robot part includes a sensor device configured and positioned to sense the surroundings of the parking robot and determine the location of obstacles for the parking robot with the lifted-up transportation vehicle in the sensed surroundings, and a control device configured to determine respective travel trajectories for both the main robot part and the secondary robot part,
• wherein a first side of the secondary robot part is initially attached to a first side of the main robot part, wherein the secondary robot part is controlled based on the travel trajectory determined by the main robot part,
• wherein the main robot and the secondary robot each have a pair of wheel support arms on two opposite sides, and
• wherein the main robot part and the secondary robot part are controlled and configured to move under the transportation vehicle while the secondary robot part is attached to the main robot part with the wheel support arms being completely folded-in and is further configured to disconnect the secondary robot part from the main robot part after the main robot part and the secondary robot part are moved into a position under the transportation vehicle so as to position the main robot part and the secondary robot part each in a region of one of the wheel axles beneath the transportation vehicle and to lift up respective wheels of the respective wheel axle of the transportation vehicle by folding out the respective pairs of wheel support arms.
