    摘要: A position determining system for a vehicle comprises an imaging unit for collecting image data. A wireless device reads or interrogates a radio frequency identification tag. An identification module determines whether the collected image data contains a visual landmark. A confirmation module determines whether the identified visual landmark is associated with a corresponding radio frequency identification tag having a particular tag identifier. A range finder or distance estimator determines a position offset of the vehicle with respect to the identified visual landmark. A data processor determines a vehicular position of the vehicle based on the determined position offset and a stored reference position associated with at least one of the visual landmark and the radio frequency identification tag.

    摘要: A method and a system for operating a mobile robot comprise a range finder for collecting range data of one or more objects in an environment around the robot. A discriminator identifies uniquely identifiable ones of the objects as navigation landmarks. A data storage device stores a reference map of the navigation landmarks based on the collected range data. A data processor establishes a list or sequence of way points for the robot to visit. Each way point is defined with reference to one or more landmarks. A reader reads an optical message at or near one or more way points. A task manager manages a task based on the read optical message.
