Abstract: Systems and methods are disclosed for container shuttles having omnidirectional wheels. In one embodiment, an example system for shuttle transportation may include a first linear synchronous motor arranged in a first orientation, a second linear synchronous motor arranged in a second orientation that is offset with respect to the first linear synchronous motor, and a shuttle having a permanent magnet and a plurality of omnidirectional wheels. The shuttle may be configured to be propelled in a first direction via the first linear synchronous motor and the permanent magnet, and to be propelled in a second direction via the second linear synchronous motor and the permanent magnet.

Abstract: Systems, methods, and computer-readable media are disclosed for dynamically configurable articulating surfaces for mobile carrier units. In one embodiment, an example mobile carrier unit may include a number of tiles that form a surface on which to receive an object, the tiles including a first tile in a first row and a second tile in a first column. The mobile carrier unit may include a first actuator coupled to the first tile and configured to actuate the first tile in a first direction, and a second actuator coupled to the second tile and configured to actuate the second tile in a second direction. A portion of the tiles may be configured to be actuated into angled orientations at or near a perimeter of the object, such that the object is prevented from sliding along the surface past the tiles.

Abstract: Item singulation systems and methods may include an input conveyor, a separation conveyor, a turn conveyor, and an output conveyor that is positioned parallel with the input conveyor. A vision system may determine individual columns of items from among a plurality of items on the input conveyor. Operations of the input conveyor, separation conveyor, turn conveyor, and output conveyor may be controlled substantially as a pull system to transfer individual columns of items to the output conveyor, such that singulated items can be transferred by the output conveyor to downstream processes.

Abstract: Systems and methods are disclosed for a shuttle track system having a calibration shuttle for determining portions of the track having non-conforming geometry for optimum use of the shuttle track system. For example, the shuttle track system may include a track having an electromagnetic propulsion system (e.g., linear synchronous motor) embedded between two sides of the track. The calibration shuttle may move to various locations on the track and may use imaging systems for generating image data of a portion of the track. A trained model may process the image data to determine edges and surfaces of the components of the track and may determine distances between reference points on the track. The distances may be compared to threshold values to determine if they are in conformity with desired track geometry.

Abstract: Systems and methods are disclosed for elevators for material handling shuttles. In one embodiment, an example system configured to change elevation of a shuttle may include an elevator track disposed between a loading zone and an unloading zone, and a platform coupled to the elevator track and configured to move between the loading zone and the unloading zone. The platform may be configured to engage with a lower surface of the shuttle at the loading zone. The platform may be configured to lift the shuttle off a first set of rails at the loading zone, and to position the shuttle onto a second set of rails at the unloading zone.

Abstract: Systems, methods, and apparatuses are disclosed for external mobility systems for heavy machinery and equipment. In one embodiment, an example system may include a first module, a second module coupled to the first module, and a third module coupled to the first module and the second module. Systems may include an air bearing system disposed under the third module, where the air bearing system is configured to apply an upward force on the third module, and an air supply coupled to the air bearing system. The upward force on the third module may reduce a static friction of the third module with respect to a floor surface by at least 90%, such that the third module can slide from a default position to an expanded position.

Abstract: Systems, methods, and computer-readable media are disclosed for automated item sortation and container handling. In one embodiment, an example method may include determining, by a controller, a first item identifier of a first item at an induction portion of a sortation system, determining an order identifier associated with the first item identifier, and determining a first container associated with the order identifier. The method may include causing a first mobile carrier unit to receive the item, and causing the first mobile carrier unit to deliver the first item to the first container.
