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 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 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.
