1. A method for work cell and factory level automation, comprising:

  • making one or more distance measurements of one or more objects within a work cell using at least one laser scanner sensor on an automated guided vehicle (AGV);

    filtering the distance measurements of the objects that are not target features on a cradle fixture or workstand within the work cell;

    removing systematic or bias errors of the laser scanner sensor from the filtered distance measurements;

    applying a mathematical filter or estimator to the filtered distance measurements using random errors of the laser scanner sensor to generate estimated distance measurements;

    constructing a map of the target features on the cradle fixture or workstand within the work cell using the estimated distance measurements; and

    using the constructed map for path planning and navigation control of the AGV relative to the cradle fixture or workstand within the work cell.
