Rapid braking of shuttles powered by electromagnets

A system comprising:

• a track having a central axis, the track comprising a first rail segment on a first side of the central axis and a second rail segment on a second side of the central axis, the first rail segment having a first aperture and a second aperture;
• a shuttle configured to transport one or more items from a first location to a second location using the track, the shuttle comprising a permanent magnet and a first conveyor assembly having a central axis that is transverse to the central axis of the track, wherein the first shuttle is configured to support the one or more items on the first conveyor assembly;
• a set of electromagnets disposed along the central axis of the track, wherein the set of electromagnets interact with the permanent magnet to propel the shuttle;
• and
• a first brake system configured to stop movement of the shuttle, the first brake system comprising:
• a first housing;
• a first pin configured to pass through the first aperture, wherein the first pin is biased in an extended position;
• a second pin configured to pass through the second aperture, wherein the second pin is biased in the extended position;
• a first actuator configured to actuate one or more of the first pin and the second pin from a retracted position to the extended position;
• a second actuator configured to actuate one or more of the first pin and the second pin from the extended position to the retracted position;
• and
• a first controller configured to control operation of the first brake;
• wherein the first brake system is coupled to the track at an induction station.
