1. A system comprising:
a shuttle configured to transport individual items from a first location to a second location using the set of rails, the shuttle comprising:
a first set of wheels disposed at a first side of the shuttle;
a second set of wheels disposed at a second side of the shuttle; and
a permanent magnet coupled to a lower surface of the shuttle; and
a calibration table comprising a mechanical template and an electromagnet, wherein the mechanical template is configured to be moved with respect to the calibration table, and wherein the electromagnet is configured to engage with the permanent magnet on the shuttle;
wherein the calibration table is configured to be used for calibration of the shuttle by performing a method comprising:
positioning the shuttle on a calibration table;
energizing an electromagnet coupled to the calibration table;
determining a detected edge of the permanent magnet;
determining a first location to position a power connector of the shuttle along an X-axis based at least in part on the detected edge and a mechanical template coupled to the calibration table; and
securing the power connector in the first location.
 
5. A method for calibration of a shuttle coupled to a permanent magnet, the method comprising:
positioning the shuttle on a calibration table;
energizing an electromagnet coupled to the calibration table;
determining a detected edge of the permanent magnet;
determining a first location to position a connector of the shuttle along an X-axis based at least in part on the detected edge; and
securing the connector in the first location.
 
16. A method for calibration of a shuttle coupled to a permanent magnet, the method comprising:
positioning the shuttle on a calibration table, the calibration table comprising a mechanical template that is configured to be moved and an electromagnet;
energizing the electromagnet;
determining a detected edge of the permanent magnet;
de-energizing the electromagnet;
determining a first location to position a connector of the shuttle along an X-axis based at least in part on the detected edge and the mechanical template; and
securing the connector in the first location.
