    Abstract: An automatic guidance system is adapted to be mounted on a work vehicle such as a farm tractor for assisting an operator steer the vehicle on a desired track relative to a furrow. The system includes sensors for transmitting and receiving ultrasonic ranging signals. The sensors are ultrasound transducers mountable on ends of a planter drawn by the vehicle for directing ranging signals downwardly toward field adjacent of a furrow such that the ranging signals strike the field or furrow and are reflected back into the respective sensor. Guidance logic stored in a memory of a controller is executed by a processor to determine tractor headway direction and headland turning directions representative of desired tractor headway and headland turning directions, and a human interface device generates guidance images viewable by an operator for steering the tractor relative to furrows in the field and in the headland.

    Abstract: The present application relates to a multi-sensor-fusion-based autonomous mobile robot indoor and outdoor positioning method and a robot. The method includes: acquiring GPS information and three-dimensional point cloud data of a robot at a current position; acquiring, a two-dimensional map corresponding to the GPS information of the robot at the current position; projecting the three-dimensional point cloud data of the robot at the current position onto a road surface where the robot is currently moving, to obtain two-dimensional point cloud data of the robot at the current position; and matching the two-dimensional point cloud data of the robot at the current position with the two-dimensional map corresponding to the GPS information of the robot at the current position, to determine the current position of the robot.

    Abstract: The invention relates to a method for navigating an industrial truck in a predetermined area with the following method steps:



    providing a map of the predetermined area with at least one permanent landmark,
    entering a temporary landmark in the map, when the temporary landmark is created,
    deleting the temporary landmark from the map when the temporary landmark is removed, and
    navigating the industrial truck in the predetermined area on the basis of the map having the permanent landmark and the temporary landmark.




    In this way, the navigating of a preferably autonomously or partly autonomously driving industrial truck in a predetermined area, such as at a depot, is improved and in particular is made safer and more reliable.

    Abstract: A system for autonomous or semi-autonomous operation of a vehicle is disclosed. The system includes a machine automation portal (MAP) application configured to enable a computing device to (a) display a map of a work site and (b) provide a graphical user interface that enables a user to (i) define a boundary of an autonomous operating zone on the map and (ii) define a boundary of one or more exclusion zones. The system also includes a robotics processing unit configured to (a) receive the boundary of the autonomous operating zone and the boundary of each exclusion zone from the computing device, (b) generate a planned command path that the vehicle will travel to perform a task within the autonomous operating zone while avoiding each exclusion zone, and (c) control operation of the vehicle so that the vehicle travels the planned command path to perform the task.
