  • Publication number: 20140214258
    Abstract: 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.

  • Publication number: 20140195076
    Abstract: Included are embodiments for providing vehicle control limits. One embodiment of a system includes a navigation system and a vehicle that includes a memory component that stores a program. Embodiments of the system are configured to receive an indication for automatic control of the vehicle, receive a route for the vehicle to reach a destination for completing a work order from the navigation system, and determine a vehicle limit, wherein the vehicle limit is based on a current state of the vehicle. Some embodiments are configured to communicate the vehicle limit from a vehicle control module (VCM) to a navigation control module (NCM), determine, via the NCM, an automatic command based on the destination and the vehicle limit and send the automatic command to a motor of the vehicle.

  • Publication number: 20140188324
    Abstract: Included are systems and methods for providing a vehicular navigation control interface. Some embodiments include a navigation system and a vehicle with a vehicle control module (VCM), a navigation control module (NCM), and a navigation control interface, where the VCM receives a manual command from an operator to implement a manual control function. In some embodiments the NCM receives an automatic command from the navigation system to implement an automatic control function via the VCM and the navigation control interface directly connects the VCM and the NCM to facilitate communication between the VCM and NCM for implementing automatic mode and for reporting implementation of a manual mode.
