The present invention relates to cutting tools, in particular, to control systems for cutters such as vegetation cutters, especially hedge cutters or trimmers (10). Hedge cutters (10) frequently suffer in use from a problem of blocked cutting blades when they encounter a twig or branch whose size or density exceeds the capacity of the blades. We describe a vegetation cutting apparatus (10) having a plurality of cutting blades (11,12), at least one of which blades (11,12) is drivable by an electric motor. At least one driven blade (11,12) is movable between two predefined points of maximum travel. The apparatus (10) includes a control mechanism which causes a change of direction in the movement of the at least one movable blade at a point intermediate the points of maximum travel in response to an event sensed by the control mechanism.

An agricultural robot system and method of harvesting, pruning, culling, weeding, measuring and managing of agricultural crops. Uses autonomous and semi-autonomous robot(s) comprising machine-vision using cameras that identify and locate the fruit on each tree, points on a vine to prune, etc., or may be utilized in measuring agricultural parameters or aid in managing agricultural resources. The cameras may be coupled with an arm or other implement to allow views from inside the plant when performing the desired agricultural function. A robot moves through a field first to “map” the plant locations, number and size of fruit and approximate positions of fruit or map the cordons and canes of grape vines. Once the map is complete, a robot or server can create an action plan that a robot may implement. An action plan may comprise operations and data specifying the agricultural function to perform.

A search system for a tool. A border cable separates inner and outer areas. A generator feeds the border cable with current, whose magnetic field affects a sensing unit on the tool, and the sensing unit emits signals to a control unit that directs the tool's motion. The current contains at least two components of different frequency. A search cable is placed within the inner area so that it separates a search area, and is fed by a signal generator with an adapted current (e.g., the current direction alternates to be either in phase or out of phase in relation to the current direction in the border cable) so that the magnetic fields in the different areas provide at least three patterns. Accordingly, the control unit can separate the inner, outer, and search areas.

The invention relates to an agricultural working machine (1), in particular a forage harvester (2), with at least one spout (4) for conveying received and processed crop (7) to a transport vehicle (6, 25), wherein an electro-optical device (18) is provided for the direction control of the spout (4) at least during the process of conveying to the transport vehicle (6, 25), and wherein the electro-optical device (18) detects characteristic parameters (30) of the spout (4) and characteristic parameters (30) of the transport vehicle (6) and/or the agricultural working machine (1). This ensures that a control of a spout (4) of agricultural working machines (1, 2) is provided which almost completely relieves the operator of the agricultural working machine (1, 2) of the task of monitoring the spout.

Embodiments of the invention comprise a system and method that enable robotic harvesting of agricultural crops. One approach for automating the harvesting of fresh fruits and vegetables is to use a robot comprising a machine-vision system containing rugged solid-state digital cameras to identify and locate the fruit on each tree, coupled with a picking system to perform the picking. In one embodiment of the invention a robot moves through a field first to “map” the field to determine plant locations, the number and size of fruit on the plants and the approximate positions of the fruit on each plant. A robot employed in this embodiment may comprise a GPS sensor to simplify the mapping process. At least one camera on at least one arm of a robot may be mounted in appropriately shaped protective enclosure so that a camera can be physically moved into the canopy of the plant if necessary to map fruit locations from inside the canopy. Once the map of the fruit is complete for a field, the robot can plan and implement an efficient picking plan for itself or another robot. In one embodiment of the invention, a scout robot or harvest robot determines a picking plan in advance of picking a tree. This may be done if the map is finished hours, days or weeks before a robot is scheduled to harvest, or if the picking plan algorithm selected requires significant computational time and cannot be implemented in “real time” by the harvesting robot as it is picking the field. If the picking algorithm selected is less computationally intense, the harvester may calculate the plan as it is harvesting. The system harvests according to the selected picking plan. The picking plan may be generated in the scout robot, harvest robot or on a server. Each of the elements in the system may be configured to communicate with each other using wireless communications technologies.

A spout control system controls and aims a spout and a spout cap of a crop harvesting vehicle with respect to a separate crop hauling vehicle moving with the harvesting vehicle. The control system includes a video camera which is mounted on the cap and which views a field of view which includes a portion of the hauling vehicle. An image signal generated by the camera is received by an image processing unit. The image processing unit processes a digitized form of the image signal and automatically generates spout and cap control signals as a function thereof. Actuators automatically aim the spout and the cap in response to the control signal.

A control arrangement is provided for controlling the transfer of agricultural crop from a harvesting machine to a transport vehicle, the transport vehicle comprising a loading container. The control arrangement based on signals from a sensor arrangement detects the fill level and/or the outer contours of the loading container and controls the position of the output end of a discharge device with respect to the harvesting machine and/or the ejection direction of the discharge device, and/or the position of the transport vehicle with the loading container with respect to the harvesting machine, automatically in such a manner that the loading container is successively filled with the crop. It is further proposed that the sensor arrangement is designed to detect the position of a second loading container and that the control arrangement can be operated so that after detection of an overall sufficiently filled first loading container, the discharge device will be automatically aligned to the second loading container based on the signals from the sensor arrangement.

A crop harvesting header includes a center portion mounted on two spring arms and two separate wings pivotally connected to the center portion. The wings are connected to the center portion by interconnecting linkages which transfer weight from the wings to the spring arms each including a balance beam arranged to balance the lifting force from the spring arm with the downward forces from the center portion and wing such that the downward force on a skid plate of each portion on the ground varies automatically as the total downward force is varied. The balance beams apply force to the linkages by a compression member to reduce forces. The movement caused by floating of the header and the change of angle of the header are compensated at the balance beam to ensure that the force to the wings is reduced as the requirement caused by changes in geometry reduces.
