  • Publication number: 20230280754
    Abstract: Embodiments provided herein include systems and methods for object detection in an environment. One embodiment of a system includes a vehicle with a wireless communication receiver for receiving communication from a wireless communication transmitter that is placed on a first object and a computing device that includes a memory component and a processor. The memory component may store logic that causes the system to receive a communication from the wireless communication transmitter, receive proximity data related to a second object, and determine a second location of the second object. Some embodiments cause the system to determine a control zone along a current path of the vehicle based on a speed of the vehicle, and in response to determining that at least one of the following enters the control zone: the first object or the second object, reduce the speed of the vehicle.

  • Publication number: 20230273618
    Abstract: A materials handling vehicle includes a camera, odometry module, processor, and drive mechanism. The camera captures images of an identifier for a racking system aisle and a rack leg portion in the aisle. The processor uses the identifier to generate information indicative of an initial rack leg position and rack leg spacing in the aisle, generate an initial vehicle position using the initial rack leg position, generate a vehicle odometry-based position using odometry data and the initial vehicle position, detect a subsequent rack leg using a captured image, correlate the detected subsequent rack leg with an expected vehicle position using rack leg spacing, generate an odometry error signal based on a difference between the positions, and update the vehicle odometry-based position using the odometry error signal and/or generated mast sway compensation to use for end of aisle protection and/or in/out of aisle localization.

  • Patent number: 11733700
    Abstract: A process for automating control of an industrial vehicle based on location comprises scanning an environment in a travel direction of the industrial vehicle, by using an optical scanner affixed to the industrial vehicle. A marker defined by a series of tags is identified by recursively receiving a reflection of the optical scanner; determining if the reflection is indicative of an optical tag; and concatenating the indication of an optical tag to the marker. Once the marker is identified, the marker is transformed into an environmental condition and a status of the vehicle is determined, where the status correlates to the environmental condition. Further, an automated control is applied on the industrial vehicle based on the environmental condition and the status of the industrial vehicle.

  • Patent number: 11694572
    Abstract: A processor on an industrial vehicle is programmed to identify a metric that characterizes an event associated with an operator of the industrial vehicle, where the metric has a performance parameter to evaluate against the event, and a behavior modification action that defines a desired operator behavior in response to the event. The processor is further operatively programmed to monitor for the event, and record event data that characterizes a response of the vehicle operator to the event. In response to detecting an event, the processor evaluates the recorded event data against the performance parameter to determine whether the vehicle operator demonstrated appropriate behavior for the event, computes a vehicle operator score based upon the evaluation, and performs the behavior modification action where the operator has not been inculcated to respond to the event.
