Provided is a method for delivering goods in collaboration of a plurality of autonomous vehicles including a master vehicle and one or more slave vehicles. The method comprises calculating, by the master vehicle among the plurality of autonomous vehicles, a floor area required for unloading the goods based on a size of the goods, searching and determining, by the master vehicle, a region providing a flat area greater than or equal to the floor area as a goods handing over point, providing, by the master vehicle, position information of the goods handing over point to the one or more slave vehicles so that the one or more slave vehicles are gathered to the goods handing over point, providing, by the master vehicle, the position information of the goods handing over point to an unmanned aerial vehicle so that the unmanned aerial vehicle moves to the goods handing over point, determining, by the master vehicle, a portion of the goods to be supported by each autonomous vehicle based on a size of delivery target goods, moving, by each autonomous vehicle located at the goods handing over point, to a position corresponding to the determined portion, taking over the goods from the unmanned aerial vehicle and loading them together by collaborating with each autonomous vehicle at the moved position, and delivering the loaded goods to a destination by the plurality of autonomous vehicles.

A robotic under surface loader includes a mobility platform, a parallel manipulator, and a cradle. The mobility platform enables the robotic under surface loader to be moved into place beneath a downwardly facing surface to which a payload is to be attached. The parallel manipulator, which is carried by the mobility platform, carries the cradle, which may in turn carry a payload. The parallel manipulator may position the cradle in six degrees-of-freedom and, thus, precisely position a payload carried by the cradle in a location and an orientation that will facilitate its interaction with (e.g., attachment to, etc.) the downwardly facing surface. Methods for attaching objects, including large, heaving objects, to downwardly facing surfaces are also disclosed.

A trailer includes a load-bearing carrier frame which is guided on an undercarriage and includes a lateral longitudinal member and two cross members protruding at right angles from either end thereof. Between these, a central member is secured to the longitudinal member, parallel to the cross members, and a loading opening is formed opposite said longitudinal member. A lifting device is arranged, for mutual height adjustment purposes, between the carrier frame and the undercarriage. A load-clasping gripping unit may be arranged on the central member and may be displaced in the transverse direction between the longitudinal member and the loading opening.

The present invention concerns a method for loading and/or unloading a loading space delimited by structural elements of at least one road or rail vehicle using a manipulator to move the loads from outside the loading space to a position onto the structural elements in the loading space and vice versa. The method includes: inputting or importing primary data relative to the loads into a logic controller, automatically calculating the optimum loading position for each load, determining the automated movements of the manipulator, automatically picking up a pallet in a storage position inside the loading space with the manipulator and positioning the pallet in a loading position located at the rear of the vehicle, placing a load on the pallet, and automatically moving the pallet supporting the load into the optimum loading position, and locking the pallet to the structural elements.

The present invention relates to a tow trailer having a structure (5) for lifting and transporting cargo and unloading them, the trailer is drawn by a suitable tow apparatus. The trailer comprises a lifting device (1) to lift and unload the cargo, wherein the lifting device is coupled to forks. The trailer moves stably due to mounting the lifting device stably in a part of the front side of the trailer, and the presence of wheels mounted in both sides thereof. The trailer has a bar (8) in the rear side, and it also has one or more barriers (7) in the middle of the trailer so as to be under the cargo. The trailer is provided with a trailer jack (2) mounted in the bearing positions of the trailer in order to stabilize it during lifting or unloading the cargo.
