In some embodiments, methods and systems are provided that provide for facilitating delivery, via autonomous ground vehicles, of products ordered by customers of a retailer to customer-specified restricted areas accessible by an entryway openable via an access code.

A machine control system includes an agricultural work machine having an ECU coupled via a system bus to control engine functions, a GPS receiver, data collector, and specialized guidance system including a stored program. The data collector captures agricultural geospatial data including location data for the work machine and data from the ECU, and executes the stored program to: (a) capture geometries of the farm; (b) capture agricultural geospatial data; (c) automatically classify the agricultural geospatial data using the geometries of the farm, into activity/event categories including operational, travel, and ancillary events; (d) aggregate the classified data to create geospatial data events; (e) match the geospatial data events to a model to generate matched events; (f) use the matched events to generate actionable information for the working machine in real time or near real-time; and (g) send operational directives to the agricultural work machine based on the actionable information.

A mobile robot is configured to navigate on a sidewalk and deliver a delivery to a predetermined location. The robot has a body and an enclosed space within the body for storing the delivery during transit. At least two cameras are mounted on the robot body and are adapted to take visual images of an operating area. A processing component is adapted to extract straight lines from the visual images taken by the cameras and generate map data based at least partially on the images. A communication component is adapted to send and receive image and/or map data. A mapping system includes at least two such mobile robots, with the communication component of each robot adapted to send and receive image data and/or map data to the other robot. A method involves operating such a mobile robot in an area of interest in which deliveries are to be made.

A method for localizing a vehicle comprises transmitting first position data related to a first position of the vehicle at a first point in time from the vehicle to a server. The server computes second position data related to the first position of the vehicle at the first point in time based on the received first position data. The server transmits the second position data from the server to the vehicle. The vehicle computes third position data related to a second position of the vehicle at a second point in time based on the received second position data. The second point in time is later than the first point in time.

An autonomous electric mower for mowing a lawn comprises a frame, drive wheels, cutting deck, computer, a Lidar sensor, at least one color and depth sensing camera. The computer is programmed and operable to: determine the location of the mower; detect obstacles; and to instruct the mower to avoid the obstacles. Advantageously, the system is operable to analyze the data from the multiple sensors and to instruct the mower to continue to safely operate and cut the lawn despite one or more of the sensors being obstructed. Novel route planning methods are also described.

A work vehicle includes: an electronic control system for automatic driving; and a cabin with which a boarding space is formed. The electronic control system includes an antenna unit for satellite navigation, and the antenna unit is attached to a central area of a roof of the cabin in a left-right direction. An upper surface of an area of the roof around the antenna unit is formed so as to be an inclined surface that is inclined in a front-rear direction. Left and right end portions of the roof are provided with left and right bulging edge portions that bulge upward from the left and right end portions and have a length that spans between front and rear ends of the roof, and water drain grooves that guide water on the roof toward the left and right bulging edge portions such that water detours the antenna unit.

A system is for determining a position on a golf course. The system has a master unit and at least one slave unit. The master unit and the at least one slave unit are adapted to communicate through a telecommunications network. The master unit comprises a receiver for a satellite navigation system, the receiver being operable at a fixed position on the golf course. The master unit is configured to: obtain a position determined by the receiver; process the displacement between the obtained position and the fixed position; and make the processed displacement available to the at least one slave unit through the telecommunications network. A slave unit then makes use of the processed displacement to improve positions determined by itself.

A robotic work tool system (200) for defining a working area perimeter (105). The robotic work tool system (200) comprises a robotic work tool (100) and a controller (210). The robotic work tool (100) comprises a position unit (175) and a sensor unit (170). The controller (210) is configured to receive, from the sensor unit (170), edge data indicating whether the robotic work tool (100) is located next to a physical edge (430). The controller (210) is further configured to control the robotic work tool (100) to travel along the physical edge (430) while the edge data indicating that the robotic work tool (100) is located next to the physical edge (430) and to receive, from the position unit (175), position data while the robotic work tool (100) is in motion. The controller (210) is configured to determine, based on the edge data and position data, positions representing the physical edge (430) and to define, based on the determined positions, at least a portion of the working area perimeter (105).

A method for operating a robotic work tool (1) comprising a sensor for detecting a boundary wire (3) demarcating a work area (2). The method comprises the steps of detecting (9) at least a partial crossing of the boundary wire (3), allowing (12) a crossing of the boundary wire (3) by an offset, switching (8) between a first offset setting and at least a second offset setting of the work tool (1) based on one or more events (7). A robotic work tool (1) comprises a controller for controlling the operation of the robotic working tool (1). The controller is configured to: control the work tool (1) to operate within the work area (2), determine whether the work tool (1) crosses the boundary wire (3), allow a crossing of the wire (3) by the offset, and switch (8) between at least two offset settings stored in the work tool (1).
