  • Patent number: 8326474
    Abstract: We provide a method for operating a navigation system for a motor vehicle in a road network, and to a navigation system. To this end, first a zone of the road network is provided with an emissions class-dependent drive-through restriction, wherein the motor vehicle is associated with at least one emissions class. First, information about the geographical location of the zone and about the emissions class at least required there is stored in the navigation system. Then, information about the at least one emissions class of the motor vehicle is entered into the navigation system. Thereafter, the information entered is considered in the destination guidance process, wherein destination guidance into or through the zone is avoided if the at least one emissions class of the motor vehicle is affected by emissions class-dependent drive-through restrictions in the zone.

  • Patent number: 8274406
    Abstract: The invention is related to methods and apparatus that use a visual sensor and dead reckoning sensors to process Simultaneous Localization and Mapping (SLAM). These techniques can be used in robot navigation. Advantageously, such visual techniques can be used to autonomously generate and update a map. Unlike with laser rangefinders, the visual techniques are economically practical in a wide range of applications and can be used in relatively dynamic environments, such as environments in which people move. One embodiment further advantageously uses multiple particles to maintain multiple hypotheses with respect to localization and mapping. Further advantageously, one embodiment maintains the particles in a relatively computationally-efficient manner, thereby permitting the SLAM processes to be performed in software using relatively inexpensive microprocessor-based computer systems.

  • Patent number: 8275493
    Abstract: A system and method are provided for launching and recovering an unmanned, water-born vehicle (UWBV) from a mother ship. The UWBV mimics the behavior of dolphins and is positioned ahead of the ship in preparation for bow riding. The UWBV uses a guidance system to position and keep in the bow wave. A high-frequency (HF) sonar transceiver array aboard the ship computes and sends course corrections to maintain the UWBV within the bow wave. The frequency range of the HF array can be 100 kHz or higher due to the short distance between the ship and the UWBV. Accordingly, the HF array can have a small aperture allowing for accurate bearing resolution. Course corrections can be sent on a near-continuous basis such that changes in thrust and rudder angle can be minimized to allow for accurate control of the UWBV.

  • Patent number: 8271158
    Abstract: A system maintains communication between a plurality of unmanned vehicles within an environment. The system includes a sensor component and an evaluator. The sensor component senses objects within the environment. The sensor component is located on a first unmanned vehicle. The evaluator evaluates data from the sensor component. The evaluator is located on the first unmanned vehicle. The evaluator compares data for the first unmanned vehicle and a second unmanned vehicle and determines whether a trajectory of one of the first and second unmanned vehicles may be modified to maintain communication between the first unmanned vehicle and the second unmanned vehicle.

  • Patent number: 8271132
    Abstract: Systems, methods, and user interfaces are used for controlling a robot. An environment map and a robot designator are presented to a user. The user may place, move, and modify task designators on the environment map. The task designators indicate a position in the environment map and indicate a task for the robot to achieve. A control intermediary links task designators with robot instructions issued to the robot. The control intermediary analyzes a relative position between the task designators and the robot. The control intermediary uses the analysis to determine a task-oriented autonomy level for the robot and communicates target achievement information to the robot. The target achievement information may include instructions for directly guiding the robot if the task-oriented autonomy level indicates low robot initiative and may include instructions for directing the robot to determine a robot plan for achieving the task if the task-oriented autonomy level indicates high robot initiative.

  • Patent number: 8265818
    Abstract: A command and control system is provided including a core unit, with a processor and a map display engine. The core unit is configured to exchange information with a multi-domain heterogeneous unmanned vehicle command and control module, a multi-sensor command and control module, and an asset tracking module. The asset tracking module estimates a location of an indeterminate object. A control unit exchanges information with an input device. A detecting unit detects modules that are associated with the core unit. A subscription unit logs parameters associated with the detected modules and determines types of data to send to the detected units based on the parameters. A script unit receives and implements command and control scripts for the detected modules. A display output provides display information of a combined representation of information from the detected modules and map information, including locations of the vehicles and sensors under control and the estimated location of the indeterminate object.

  • Patent number: 8260482
    Abstract: A passenger in an automated vehicle may relinquish control of the vehicle to a control computer when the control computer has determined that it may maneuver the vehicle safely to a destination. The passenger may relinquish or regain control of the vehicle by applying different degrees of pressure, for example, on a steering wheel of the vehicle. The control computer may convey status information to a passenger in a variety of ways including by illuminating elements of the vehicle. The color and location of the illumination may indicate the status of the control computer, for example, whether the control computer has been armed, is ready to take control of the vehicle, or is currently controlling the vehicle.

  • Patent number: 8260483
    Abstract: The present invention provides a guidance, navigation, and control method and system for an underground mining vehicle that allow said vehicle to be taught a route by a human operator and then have it automatically drive the route with no human intervention. The method works in three steps: teaching, route profiling, and playback. In the teaching step the vehicle is manually driven by a operator along a route which can consist of an arbitrary sequence of maneuvers including tramming forwards, switching directions, tramming backwards, turning, or pausing movement. During this phase raw data from vehicle-mounted sensors including odometric sensors and rangefinders are logged to a file throughout teaching for later processing. During the (offline) route profiling step, the raw data in the log file are processed into a route profile, and a profile of desired speed as a function of distance along the path.

  • Publication number: 20120221186
    Abstract: Methods and devices to physically stabilize a unit load of stapled unit loads such as at least two standard containers applied atop each other and on top of at least one Automatically Controlled Vehicle (AGV), during transport of the load in all directions on the ground. The AGV arranged below the unit load has at least one wheel-bogie having at least one wheel at each corner, the bogie being controllably pivotable at its geometrical center to a frame of the AGV with each wheel being controllably pivotable at its respective fixation points. During transport in a longitudinal direction of the total unit, each bogie is translated to a diagonal position in relation to its position of introduction as the wheels simultaneously are controlled so as to maintain their rolling direction in the direction of transport, so as to enhance the traction of the AGV.
