InactiveUS20050007057A1Improve accuracyMinimal period of timeLawn-mowersDistance measurementProximity sensorUncrewed vehicle
A method for automatically operating a robot, attached to a lawnmower or other unmanned machine, within an enclosed area is disclosed. The method includes the steps of: 1) providing the following elements: a proximity sensor positioned on the robot, a boundary along the perimeter of the working area and along the perimeter of each area enclosed in the working area in which the robot should not operate, the boundaries being detectable by the proximity sensor, a processing unit connected to the proximity sensor and receiving an input therefrom, a navigation unit on the robot to determine the coordinates of the robot relative to an arbitrary origin, a direction finder, and a memory to store values generated by the processing unit; and 2) causing the robot to move along each of the boundaries provided around or within the working area, to detect the boundaries and to memorize their shape, and to store in the memory values representative of the coordinates of the boundaries, thereby to generate a basic map of the working area. When the robot is to operate within the area, the method includes the steps of: (a) causing the robot to start from a starting point having known coordinates within the basic map of the working area; (b) continuously determining the coordinates of the robot by analyzing data obtained from the navigation unit and by detecting the vicinity of a boundary; and (c) correcting the actual position of the robot on the basic map by comparing the calculated and the actual coordinates of each detected boundary.

Large area position/proximity correction device with alarms using (D)GPS technology
A collar to be worn on an object or a large or small animal has been designed incorporating (D)GPS technology. The operation of the device includes programming the three dimensional boundary into the memory of the device and simply installing the collar on the animal. As the animal approaches the preprogrammed boundary, a first alarm sounds when the subject is within an arbitrary user defined distance, and a second more drastic alarm such as a shock correction is applied when the subject approaches a second position closer to the boundary. Means to easily program the device are also included in the system. The device has the capability to call or transmit important information such as location, speed, identity, and medical parameters, etc. to a station automatically or when polled. All necessary analog and digital circuitry, microprocessor, programming, communications hardware are integrated into the collar. The device also has applications in land, air and sea navigation, farming, construction, tracking stolen vehicles, and keeping track of children. This device could also be embedded in a specialized lawnmower that would know where your yard ended and your neighbor's began, and traverse around all obstacles in the yard. Important Military applications would include warning and directing soldiers of front line boundaries, minefield mapping and 3-D direction around MOA's for aircraft.
