  • Patent number: 9817402
    Abstract: Work cell and factory level automation require that an Automated Guided Vehicle (AGV) achieve demanding positional accuracy and repeatability relative to a cradle fixture or workstand within a work cell. The AGV makes distance measurements of objects within the work cell using laser scanner sensors. The distance measurements are filtered of objects that are not target features on the cradle fixture or workstand. Systematic or bias errors of the laser scanner sensor are removed from the filtered distance measurements, and a mathematical filter or estimator is applied to the filtered distance measurements using random errors of the laser scanner sensor to generate estimated distance measurements. A map of the target features is then constructed using the estimated distance measurements, wherein the map is used for path planning and navigation control of the AGV relative to the cradle fixture or workstand within the work cell.
