A process to schedule an industrial vehicle for maintenance comprises constructing a warehouse model based upon a warehouse configuration to define a dimensionally constrained environment and virtual industrial vehicles operating within the environment. A workflow model defines tasks of the virtual industrial vehicles within the defined environment of the warehouse model. A kinematic model is based upon vehicle specifications for the virtual industrial vehicles, kinematic functions of the virtual industrial vehicles, constraints of the defined environment of the warehouse model, and a cutback curve computed for a parameter of a kinematic function of the virtual industrial vehicle. The kinematic model is applied to the workflow model to evaluate virtual industrial vehicle performance to determine ideal results. Actual use data of the industrial vehicle is collected during the industrial vehicle operation. The industrial vehicle is scheduled for maintenance based on a comparison of the actual use data to the ideal results.

Industrial vehicle fleet recommender

A process for recommending a fleet of industrial vehicles comprises receiving, via a user interface, input variables concerning a warehouse configuration and operational variables concerning a fleet configuration. Instances of a warehouse model, an operations model, vehicle specifications, and workflow parameters are created where the workflow parameters are established workflow models derived from the warehouse configuration and vehicle specifications. A workflow model is simulated using kinematic models of the vehicles by defining a workflow model defining tasks of the industrial vehicles within an environment associated with performance of an operation, wherein the workflow model is based on the workflow parameters and associating the tasks with the kinematic models, which incorporate cutback curves. The kinematic model is applied to the workflow model based upon travel paths of the workflow model to determine results. A recommendation for vehicles of a vehicle type based on the simulation results is recommended.

A process for modifying vehicle performance parameters for one or more kinematic functions while executing an assigned task is disclosed. The process comprises receiving, for an industrial vehicle, a job specification and decomposing the job specification into a workflow model, with the workflow model defining the tasks of the industrial vehicle. The process further comprises associating the tasks with a kinematic model. The kinematic model is generated by identifying the kinematic function of the industrial vehicle, receiving constraints associated with an operation of the industrial vehicle, and computing a cutback curve for a parameter of the kinematic function. The kinematic model is applied to the workflow model. The performance parameter of the industrial vehicle is modified based on the applied kinematic model to the workflow model.

Warehouse mapping tools according to the present disclosure comprise a mobile mapping interface and a mobile computing device in communication with the mobile mapping interface. The mobile computing device can be configured to access waypoint data comprising location coordinates of a set of mapping waypoints, present graphical representations of the set of mapping waypoints at discrete locations in a representation of a warehouse environment, access mobile mapping data representing an elapsed travel path, access error metric data, present a graphical representation of the error metric data, and indicate a validation state of the elapsed travel path segment. In other embodiments, a warehouse mapping tool comprises a remote computer that is configured to communicate with a mapping vehicle and that can be used to facilitate navigation, localization, or odometry correction with respect to an industrial vehicle in the warehouse. In still other embodiments, mapping vehicles comprising warehouse mapping tools are provided.

A method and apparatus for using unique landmarks to position industrial vehicles during start-up. In one embodiment, a method of using pre-positioned objects as landmarks to operate an industrial vehicle is provided. The method comprises identifying a start-up scenario from sensor data, wherein the start-up scenario comprises a unique marker start-up or a pre-positioned object start-up. in response to the identified start-up scenario, either a unique marker or pre-positioned object is identified within a physical environment, wherein the pre-positioned object or unique marker corresponds with a sub-area of the physical environment. The industrial vehicle pose is determined in response to the identity of the pre-positioned object or unique marker and the industrial vehicle is operated based on the determined industrial vehicle pose.

Method and apparatus for using unique landmarks to locate industrial vehicles at start-up

According to the embodiments described herein, an industrial vehicle can include an Environmental Based Localization (EBL) sensor communicatively coupled to one or more processors. The EBL sensor can detect objects within a field of view. The one or more processors execute machine readable instructions to access a feature set and an occlusion set that are associated with an industrial facility. An occlusion path that intersects a detectable occlusion of the occlusion set and the sensor origin of the EBL sensor can be determined. A feature intersection of the occlusion path can be determined. A detectable feature can be classified as an occluded detectable feature based at least in part upon location of the feature intersection. The industrial vehicle can be navigated through the industrial facility utilizing the feature set exclusive of the occluded detectable feature.
