Abstract:
An apparatus and method for detecting the presence of a slippery material, such as ice, on a surface and for taking action to mitigate the potential hazard presented by such material automatically with little or no human intervention. In accordance with an illustrative embodiment, a mobile machine, such as a robot, is controlled to move automatically across a surface along a path. The mobile machine automatically detects for the presence of a slippery material on the surface as it traverses the surface. The mobile machine automatically takes an action to mitigate the slippery material in response to the detection of the slippery material on the surface.
Abstract:
A method for scheduling mowing tasks by a robotic mower is provided. An estimated height of grass cut by the robotic mower is determined for a predetermined number of past mowing tasks. The estimated height of grass cut is compared with a predicted height of grass in an operating environment for the robotic mower. Then, a mowing schedule for the robotic mower is adjusted by decreasing a time between mowing tasks in response to the estimated height of grass cut being greater than the predicted height of grass. Alternatively, the mowing schedule for the robotic mower is adjusted by increasing the time between mowing tasks in response to the estimated height of grass cut being less than the predicted height of grass.
Abstract:
The different illustrative embodiments provide an apparatus, a system, and a method for managing a portal. The different illustrative embodiments provide an apparatus comprising a locking system, a detection system, and a portal access system. The locking system is for a portal having a first side and a second side. The portal is configured to swing about an axis through the first side between an opened position and a closed position. The detection system is configured to detect when a robotic vehicle is located within a selected distance of the portal. The portal access system unlocks the portal when the portal is in the closed position and the robotic vehicle is detected within a selected distance of the portal using the detection system.
Abstract:
Therefore, the illustrative embodiments provide an apparatus for performing horticultural tasks. In an illustrative embodiment, an apparatus is comprised of a number of data storage devices, a planning process, and a processor unit. The number of data storage devices includes a knowledge base. The processor unit executes the planning process and accesses the knowledge base on the number of data storage devices to identify a horticultural need for a plurality of plants.
Abstract:
A system and method for estimating agricultural parameters for growing crops is well suited for promoting efficient utilization of agricultural inputs (e.g., water consumption). Sensors collect data via one or more vehicles equipped with location-determining receivers. A transmitter transmits the collected environmental data to a data processing system. The data processing system applies the collected environmental data to an agronomic model for determining an agricultural management parameter. A prescription is made available for application of an agricultural input (e.g., water) to a crop in a particular location consistent with the collected environmental data and the agronomic model.
Abstract:
The illustrative embodiments provide a method for processing sensor data and controlling the movement of a vehicle. An operating environment around the vehicle is identified and sensor data is selected from a set of sensors. A dynamic condition is identified using a plurality of different types of sensors on the vehicle. In response to the dynamic condition being identified, the movement of the vehicle is controlled. Sensor data for a plurality of vehicles is managed by receiving sensor data at the plurality of vehicles, each with a plurality of sensors. In response to a selected vehicle within the plurality of vehicles being unable to obtain needed sensor data, collected sensor data from a number of other vehicles in the plurality of vehicles can be obtained to form alternate sensor data used to control the vehicle.
Abstract:
The illustrative embodiments provide an apparatus for controlling a vehicle. In an illustrative embodiment, a vehicle is comprised of a machine controller, a steering system, a propulsion system, a braking system, a sensor system, and a knowledge base used by the machine controller. The machine controller identifies a dynamic condition and sends commands to the steering system, the propulsion system, and the braking system to move the vehicle.
Abstract:
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.
Abstract:
A system and method for delivering information to a user (e.g., a worker) comprises equipping a user with a data processing device associated with a portable display. A particular location or context of the user is determined. A display automatically displays information to the user based on at least one of the location of use and the determined context.
Abstract:
An agricultural data system including a vehicle, a lift mechanism associated with the vehicle, an RFID reader and a weight sensor system. The RFID reader is associated with the vehicle and/or the lift mechanism and provides for the reading of an RFID tag on an agricultural produce container. The weight sensor system is associated with the vehicle and/or the lift mechanism and it determines a weight of the container.
