摘要： A remote control device that is to be worn on the appendage of an operator includes a base portion, a wireless communication system, a control, and an insert member. The wireless communication system includes a wireless transmitter for transmitting wireless commands from the remote control device. The control is communicably coupled to the wireless communication system, wherein actuation of the control causes the wireless transmitter to transmit a wireless command. The insert member is removably attached to the base portion.

摘要： A materials handling vehicle technology monitor receives wirelessly, from a fleet of materials handling vehicles, electronic vehicle records. Each electronic vehicle record includes technology feature data recorded by a controller on an associated materials handling vehicle. Typically, the electronic vehicle record is generated in response to a corresponding technology feature on the materials handling vehicle being operated in a work environment. Moreover, each electronic vehicle record includes an operator identification of an operator of the materials handling vehicle at the time the technology feature data is recorded. The monitor also generates for each operator, an electronic measurement based upon a comparison of expected technology feature usage, e.g., a threshold, compared to the technology feature data in the received electronic vehicle records, which are associated with the corresponding operator. The process further comprises outputting to a dashboard, a graphical representation of the generated measurements.

摘要： A process for calibrating a distance and range measurement device (440,540) coupled to an industrial vehicle (442,542) comprises taking a first measurement of an emission from the device at a first yaw angle relative to a roll axis of the device. A second measurement of the emission at a second yaw angle relative to the roll axis is taken. The second yaw angle is within an angular tolerance of the first yaw angle but in an opposite direction. The device is calibrated relative to the roll axis when the first and second measurements are within a tolerance of each other. A third measurement of the distance and range measurement device beam emitted from the distance and range measurement device at a pitch angle is taken. If the third measurement and a virtual emission length are within a tolerance, then the device (440,540) is calibrated with respect to the pitch axis.

摘要： A method for operating a materials handling vehicle is provided and comprises: monitoring, by a controller, a first vehicle drive parameter during a manual operation of the vehicle by an operator; storing, by the controller, data related to the monitored first vehicle drive parameter. The controller is configured to use the stored data for implementing a semi- automated driving operation of the vehicle subsequent to the manual operation of the vehicle. The method further comprises: detecting, by the controller, operation of the vehicle indicative of a start of a pick operation occurring during the manual operation of the vehicle; and based on detecting the start of the pick operation, resetting, by the controller, the stored data related to the monitored first vehicle drive parameter.

摘要： A load wheel assembly (40, 60) is provided with: a frame member (46, 66); a side plate (42, 62) coupled to the frame member (46, 66); an axle (50, 70) extending between the frame member and the side plate; and a keeper (52, 72) coupled by a fastener (54, 74) to the frame member (46, 66) or the side plate (42, 62). The keeper is coupled to one end of the axle to prevent rotational and axial movement of the axle relative to the frame member and the side plate.

摘要： Systems and methods for a materials handling vehicle (100) configured to navigate along a warehouse environment (150) inventory transit surface, the vehicle including control architecture in communication with a drive mechanism (128), a materials handling mechanism (20), a speed zone sensing subsystem (106) configured to provide an indication of whether the vehicle is in a speed zone, and a speed control processor (104) configured to prompt the operator to reduce a vehicle speed of the vehicle to under a speed zone limit when the vehicle speed is approaching or in the speed zone, determine whether the vehicle speed is under the speed zone limit in the speed zone, and apply a speed cap to limit a maximum vehicle speed of the vehicle to a magnitude that is at or below the speed zone limit when the speed control processor has determined that the vehicle speed is under the speed zone limit in the speed zone. Other embodiments relate to application of other operation caps such as vehicle acceleration limit, lift height limit, lift speed limit and lift acceleration limit.

摘要： Vehicles, systems, and methods for navigating or tracking the navigation of a materials handling vehicle along a surface that may include a camera and vehicle functions to match two-dimensional image information from camera data associated with the input image of overhead features with a plurality of global target locations of a warehouse map to generate a plurality of candidate optical targets, an optical target associated with each global target location and a code; filter the targets to determine a candidate optical target; decode the target to identify the associated code; identify an optical target associated with the identified code; determine a camera metric relative to the identified optical target and the position and orientation of the identified optical target in the warehouse map; calculate a vehicle pose based on the camera metric; and navigate the materials handling vehicle utilizing the vehicle pose.

摘要： A materials handling vehicle operating system is provided comprising a tag layout where a plurality of entry/exit tag sets are arranged along a travel path at different ones of the entry/exit thresholds of a restricted navigation zone. Each entry/exit tag set comprises a release tag, a restriction tag, and an indicator tag. The indicator tag is positioned between the restriction tag and the restricted navigation zone. The restriction tag is positioned between the release tag and the indicator tag. The tag reader and the reader module cooperate to compare identified tag data with stored tag data and initiate a remediation operation when an indicator tag is identified in place of a restriction tag. Tag layouts for one-way and two-way travel into and out of a restricted navigation zone are also contemplated.
