Abstract: Systems and methods are disclosed for shuttle turning systems having linear synchronous motors. 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 transverse to the first orientation, and a shuttle. The shuttle may have a first permanent magnet coupled to the shuttle and a second permanent magnet coupled to the shuttle, where the first permanent magnet is arranged parallel to the first orientation and the second permanent magnet is arranged parallel to the second orientation. The shuttle may be configured to be propelled in a first direction via the first linear synchronous motor and the first permanent magnet, and to be propelled in a second direction via the second linear synchronous motor and the second linear synchronous motor.

Abstract: Systems, methods, and apparatuses are disclosed for automated container retrieval and delivery systems. In one embodiment, an example container handling system may include a platform, a first rotatable arm disposed on a lower side of the platform, where the first rotatable arm is offset from a front end of the platform, a motor configured to rotate the first rotatable arm from a first position to a second position, and a first wheel disposed at a distal end of the first rotatable arm. The container handling system may be configured to raise a container from an angled position to a horizontal position, and the container may be in the horizontal position when the first rotatable arm is in the second position.

Abstract: Systems and methods are disclosed for wireless powering and control of conveyors on shuttles. An example system may include a track, and a shuttle configured to move along the track, the shuttle having a conveyor, and a first induction coil. The system may include a second induction coil disposed at a first location along the track, where the second induction coil is configured to interact with the first induction coil to power the conveyor. The shuttle may not have an onboard power source coupled to the conveyor.

Abstract: Item singulation systems and methods may include an input conveyor, a separation conveyor, and an output conveyor that is positioned orthogonally to 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, 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 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: A conveyor system for processing items, such as manufacturers' products or boxes, from a three-dimensional arrangement to a two-dimensional arrangement includes inclined and declined conveyors. The inclined conveyor may include vacuum through perforations in the belt. A collimating conveyor includes parallel belts that operate at different speeds to space the items longitudinally apart and then align the items against sidewalls.

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.
