Aspects herein relate to using a three points to control the angular orientation of a structure via three or more jacks, and then stabilizing the structure via one or more stabilizers. In some aspects, the foregoing structure may include, for example, a motor home, recreational vehicle, travel trailer or fifth wheel trailer.

An unmanned ground vehicle (UGV) includes a mast attached to a UGV body at a base end. The mast extends a predetermined distance to a mast head which can include a mast-head device. A flipper assembly includes at least one flipper arm which is rotatably mounted to the UGV body to help facilitate UGV stability and/or mobility. A flipper actuator causes the flipper arm to rotate about a flipper rotation axis. Movement of the mast between a stowed configuration and a deployed configuration is selectively controlled by operation of the flipper assembly.

The present subject matter provides leveling systems and processes for leveling vehicles, such as recreational vehicles. The present subject matter also relates to computer program products for leveling vehicles, such as recreational vehicles, using smart devices. The leveling system can include a sensor device secured to a vehicle to sense at least one of an inclination or an orientation of the vehicle in both a pitch direction and a roll direction. The leveling system can include a smart device in communication with the sensor device to allow information received from the sensor device to be processed to provide measurements to a user and to determine the amount of adjustments needed in height to at least one of the pitch direction or the roll direction to level the vehicle.

A transportable fold-out at least partial enclosure includes in one aspect of the invention a stationary platform having a major surface defining a stationary plane, a plurality of side edges, a front edge and a back edge. A primary platform has a major surface defining a primary plane, an inside edge, an outside edge, a front edge, a back edge, the inside edge being joined to the stationary platform, the primary platform having a folded position in which the primary plane and stationary plane are oblique or orthogonal, and the primary platform having an extended position where the primary platform is unfolded from the stationary platform. An end wall assembly has at least two segments, each segment having a major surface defining a segment plane, side edges, a top edge and a bottom edge, the side edges of the segments being joined to each other, the bottom edges of each segment being joined to one of the stationary platform and the primary platform. The end wall assembly has an extended position in which the segment planes are at an angle to form a wall to both the stationary plane and the primary plane, and the end wall assembly having a folded position. At least one actuating mechanism is joined to at least one of the segments and the stationary platform or the primary platform to which said at least one of the segments is joined, said at least one actuating mechanism configured to provide a force to urge said at least one of the segments to the extended position.

An overturn prevention device relating to an embodiment includes an overturn prevention arm supported on a vehicle body such that the overturn prevention arm is rotatable on an axis of rotation extending in a top-bottom direction, the overturn prevention arm being configured to prevent the vehicle body from overturning. The overturn prevention arm moves between a retracted state where the overturn prevention arm is retracted into the vehicle body and a used state where the overturn prevention arm protrudes beyond the vehicle body.

The present disclosure discloses an automatic leveling control method for a four-leg support working platform, which comprises the steps: determining the mass center position of the working platform, determining the main bearing quadrant and distinguishing active legs from the driven leg; adjusting the driven leg to weak state, controlling all legs to synchronously actuate for leveling; calculating the limit compensating actuation length of the driven leg, and performing compensating actuation until accomplishing the leveling process. The method is advantageous in: high speed, high robustness, no repeated oscillation. The mass center always stays within the bearing zone of the active legs, thus completely eliminating capsizing risk of the working platform. The compensating actuation of the driven leg ensures there is no weak leg, and hence high attitude and load-bearing stability of the working platform is achieved.
