Modification Or Correction Of Route Information Patents (Class 701/26)
  • Patent number: 8442791
    Abstract: A position for a vehicle is corrected by detecting landmarks on the journey route and correcting the measured vehicle position when a landmark of this kind has been identified. The landmarks are stored in a database in the vehicle with associated exact GPS positions. When a landmark is reached, the associated exact GPS position is compared with the position measured in the vehicle, whereupon the measured position is corrected. In this way, the position finding can be improved.

The transiting area/starting-terminal point recognizing unit recognizes a node or a link connecting nodes together designated by the user via a remote controller as a designated transiting area, the target position as a terminal point, and a departure position as a starting point. The route candidate generating unit generates a moving route candidate connecting the terminal point and the starting point so the designated transiting area is included at least in a part of the moving route candidate. The determining unit determines the level of a possibility of contact between the robot and an object in the case where the robot is made to move along the moving route candidate, and outputs the determination result via an output device.

  • Publication number: 20120197464
    Abstract: A telepresence robot may include a drive system, a control system, an imaging system, and a mapping module. The mapping module may access a plan view map of an area and tags associated with the area. In various embodiments, each tag may include tag coordinates and tag information, which may include a tag annotation. A tag identification system may identify tags within a predetermined range of the current position and the control system may execute an action based on an identified tag whose tag information comprises a telepresence robot action modifier. The telepresence robot may rotate an upper portion independent from a lower portion. A remote terminal may allow an operator to control the telepresence robot using any combination of control methods, including by selecting a destination in a live video feed, by selecting a destination on a plan view map, or by using a joystick or other peripheral device.

  • Patent number: 8234033
    Abstract: An automated method and system includes an automatic guidance system (AGS) and swath pattern. The AGS steers a vehicle towing a rotary baler in an “S”, or oscillatory pattern around a predetermined approximate centerline of the swath path. The oscillatory pattern may be user defined. By steering the vehicle in an oscillatory pattern referenced to the A-B line, a windrow of crop material may be distributed into an even and optimal bale size and density by the baler. Bale chamber sensors detect an imbalance of crop density and in response, AGS adjusts an interval or amplitude of oscillatory pattern.

  • Patent number: 8224516
    Abstract: The different illustrative embodiments provide a method for generating an area coverage path plan using sector decomposition. A starting point is identified on a worksite map having a number of landmarks. A first landmark in the number of landmarks is identified. A path is generated around the first landmark until an obstacle is detected. In response to detecting the obstacle, the path is made linear to a next landmark. The path is generated around the next landmark.

  • Patent number: 8224563
    Abstract: The latitude/longitude and time acquired at prescribed sampling time intervals by a touring bus 1 which runs a predetermined running route are wireless-transmitted. A user 6 specifies a getting-on/off point on the basis of the latitude/longitude and time provided by the touring bus and acquires a running route inclusive of the getting-on/off point. Therefore, the user can acquire the running route inclusive of the getting-on/off point easily and instantaneously. The user can specify the getting-on/off point using the speed computed from the latitude/longitude and time acquired. Thus, the user can set his desired notifying point on the running route thus acquired. In such a configuration, there are provided a system for permitting a user of a touring bus to acquire a running route of the touring bus inclusive of a getting-on/off point easily and instantaneously and a system for notifying the arrival of the touring bus which permits the user to set his desired notifying point easily.

  • Patent number: 8209075
    Abstract: A method and system for controlling a vehicle comprises a boundary establisher for establishing a boundary of a work area. A vehicle position sensor (e.g., a location-determining receiver) determines a position of the vehicle. A planner module plans a raw turn of a vehicle to be executed in accordance with a model turn pattern if the position of the vehicle has traversed the boundary. An adjustment module may adjust the raw turn of the vehicle to a compensated turn such that an implement coupled to the vehicle follows an implement path that substantially tracks the model turn pattern.
