A lift machine includes a base having a first end and a second end, a first assembly, and a second assembly. The first end has first and second pivot points defining a first lateral axis. The second end has third and fourth pivot points defining a second lateral axis. The first assembly is pivotably coupled to the first and second pivot points. The first assembly extends away from the base in a first direction such that first and second tractive elements are longitudinally offset from the first lateral axis and spaced from the first end of the base. The second assembly is pivotably coupled to the third and fourth pivot points. The second assembly extends away from the base in a second direction such that third and fourth tractive elements are longitudinally offset from the second lateral axis and spaced from the second end of the base.

Examples relate to simultaneous localization and calibration. An example implementation may involve receiving sensor data indicative of markers detected by a sensor on a vehicle located at vehicle poses within an environment, and determining a pose graph representing the vehicle poses and the markers. For instance, the pose graph may include edges associated with a cost function representing a distance measurement between matching marker detections at different vehicle poses. The distance measurement may incorporate the different vehicle poses and a sensor pose on the vehicle. The implementation may further involve determining a sensor pose transform representing the sensor pose on the vehicle that optimizes the cost function associated with the edges in the pose graph, and providing the sensor pose transform. In further examples, motion model parameters of the vehicle may be optimized as part of a graph-based system as well or instead of sensor calibration.

A level compensator system may be configured to receive containers of different heights and position them at the same level. The level compensator system can include engagement platforms for engaging with the containers. The engagement platforms can move between an engagement configuration for engaging with the containers and a conveyance configuration for conveying of the containers relative to the level compensator.

A boom lift includes a base having a first end and an opposing second end, a turntable coupled to the base, a boom coupled to the turntable, an assembly pivotably coupled to the first end of the base, and a first actuator coupled to the first end of the base and the assembly. The assembly includes a tractive element. The assembly extends from the base such that the tractive element is longitudinally offset from and spaced forward of the first end and the opposing second end of the base.

A transport trolley for transporting a load comprising a base mounted on motorized wheels, a deck mounted to be translationally mobile on the base in a direction of translation, a first motorized system displacing the deck, a hexapod platform comprising a platform and a set of six jacks in which each is mounted articulated between the deck and the platform. The platform comprises a plurality of bearing points configured to come under the load and each bearing point takes the form of a receptacle with its opening oriented upwards. A control unit controls each motorized wheel, the first motorized system and each jack. The use of a hexapod platform makes it possible to finely position the wing at its position of fixing onto the fuselage and the use of a mobile deck supporting the hexapod platform allows for adjustability of the position despite a smaller footprint around the aircraft.

A sheet of flexible material can be deployed or stored by unfurling or furling the sheet using one or more inflatables. After the sheet is deployed to, for example, cover a load on a flatbed trailer, the inflatable can be deflated for storage. A sheet that has been removed from the load can be stored by placing an inflatable along an edge of the sheet. The inflatable is pressurized, and the sheet is furled onto the inflatable by rolling the inflatable. The inflatable is deflated and rolled up with the sheet for storage.
