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 seamless disengagement of shuttles powered by electromagnets. An example system may include a frame coupled to a track, a first conveyor disposed along the first side of the track, a second conveyor disposed along the second side of the track, and an actuator configured to drive the first conveyor and the second conveyor, where the first conveyor and the second conveyor are configured to engage a first bar disposed on a lower surface of the shuttle. The system may be configured to (i) move the shuttle from a first location along the track to a second location along the track, and (ii) pause movement of the shuttle between the first location and the second location.

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 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 and methods are disclosed for passive braking systems for container shuttles. An example system may include a track having a first portion and a ramp portion disposed at an angle, a first electromagnet disposed along the first portion, a shuttle with a permanent magnet that is configured to interact with the first electromagnet to propel the shuttle along the track, and a first metal block disposed along the ramp portion. The shuttle may enter the ramp portion at a first speed and exit the ramp portion at a second speed due to an eddy current induced in the first metal block by the permanent magnet.
