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 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.

Abstract: Systems and methods are disclosed for automated self-calibration and maintenance for container shuttles. An example system for automated repairs may include a track, a shuttle coupled to a permanent magnet, the shuttle configured to move along the track, and an electromagnet disposed along the track, where the shuttle is propelled via interaction between the electromagnet and the permanent magnet. The system may include a maintenance area accessible via the track, and a set of robotic manipulators disposed about the maintenance area, the set of robotic manipulators configured to perform automated maintenance actions on the shuttle. The system may include a first controller configured to determine that the shuttle is in need of maintenance, and automatically direct the shuttle to the maintenance area.

Abstract: Systems, methods, and apparatuses are disclosed for helical container conveyance. In one embodiment, an example container conveyance system may include a set of rails having a first rail and a second rail, the set of rails configured to guide a container from an upright position at a first point along the set of rails to an inverted position at a second point along the set of rails. The system may include a drive mechanism configured to propel the container along the set of rails, and a conveyor disposed under a portion of the set of rails corresponding to the second point.

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.
