  • Publication number: 20200399104
    Abstract: A materials handling vehicle comprises an operator compartment, a compartment tower, a multi-field scanning tool, and mechanisms that facilitate movement along a travel plane in a warehouse. The tool establishes a scan field, and, within scan field bounds, an occupancy detection field and an obstacle detection field. Tool scanning hardware is configured to generate the scan field from a point of origin that is elevated relative to the operator compartment and to expand the scan field such that it intersects the operator compartment and extends laterally beyond lateral edges of the operator compartment such that the occupancy detection field falls within the operator compartment, the obstacle detection field falls outside of the operator compartment, and the multi-field scanning tool is configured to indicate the presence of an occupant in the occupancy detection field and obstacles in the obstacle detection field.

  • Publication number: 20200371531
    Abstract: A materials handling vehicle comprising a path validation tool and a drive unit, steering unit, localization module, and navigation module that cooperate to navigate the vehicle along a warehouse travel path. The tool comprises warehouse layout data, a proposed travel path, vehicle kinematics, and a dynamic vehicle boundary that approximates the vehicle physical periphery. The tool executes path validation logic to determine vehicle pose along the proposed travel path, update the dynamic vehicle boundary to account for changes in vehicle speed and steering angle, determine whether the dynamic vehicle boundary is likely to intersect obstacles represented in the layout data based on the determined vehicle pose at candidate positions along the proposed travel path, determine a degree of potential impingement at the candidate positions by referring to the dynamic vehicle boundary and obstacle data, and modify the proposed travel path to mitigate the degree of potential impingement.

  • Patent number: 10846953
    Abstract: An evaluation of industrial vehicle performance is carried out based upon a designated task to be performed using the industrial vehicle, where the task has a corresponding metric associated therewith. Performance of the industrial vehicle during execution of the task is measured based by extracting vehicle operational data that is responsive to the corresponding metric. Also, information identifying an extrinsic factor is obtained, where the extrinsic factor is in effect at least one time during performance of the task, and which is capable of impacting a performance capability of the industrial vehicle in performing the task. Moreover, an adjusted task evaluation is created, which is indicative of industrial vehicle performance that takes into account a generated task performance score that is based upon the measured performance of the industrial vehicle in performing the task, a computed target score for the task, and the extrinsic factor.
