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.
