Abstract
Official abstract text for this publication.
Systems and methods for calibrating odometry of a materials handling vehicle. One embodiment of a method includes determining a current location of the materials handling vehicle, determining an odometry distance from the current location to a destination based on a calculation of a determined number of rotations of a wheel and a circumference of the wheel, and determining a positioning system distance from the current location to the destination. Some embodiments include comparing the odometry distance with data from the positioning system distance to calculate a scaling factor, applying the scaling factor to a fast alpha filter to achieve a fast filter result, and applying the scaling factor to a slow alpha filter to achieve a slow filter result. Similarly, some embodiments include applying the fast alpha filter to the scaling factor to smooth noise, calculating an updated odometry distance utilizing the scaling factor, and utilizing the updated odometry distance.
First claim
Opening claim text (preview).
What is claimed is: 1 . A materials handling vehicle comprising materials handling hardware, a wheel, an odometer, a positioning system, and a vehicle computing device, wherein the vehicle computing device stores logic that when executed by a processor, causes the materials handling vehicle to perform at least the following: determine a current location of the materials handling vehicle within a warehouse; determine, via the odometer, an odometry distance from the current loca…
