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.

Abstract: Systems and methods are disclosed for automated lateral transfer and elevation of sortation shuttles. An example system may include a track having a first portion arranged in a first direction, a shuttle configured to move along the track, and a shuttle carriage system configured to move in a second direction transverse to the first direction, where the shuttle is configured to move from the track to the shuttle carriage system. The shuttle carriage system may include a first frame configured to support the shuttle, a first electromagnet configured to propel the first frame, and a second electromagnet coupled to the first frame, the second electromagnet configured to propel the shuttle off the first frame.
