An apparatus for efficient targeting or removal of weeds or other plants. The apparatus may include a vehicle having a frame, a motor and a plurality of ground engaging members adapted to propel the vehicle over a surface. It may also include a robotic arm comprising a distal portion and a proximal portion coupled to the frame, and an implement, such as a tool or hoe connected to the distal portion of the robotic arm. The implement can be raised and lowered, and also moved relative to the surface by the robotic arm by pivoting or rotating the robotic arm at or near the proximal portion.

An agricultural harvesting machine includes crop processing functionality configured to engage crop in a field, perform a crop processing operation on the crop, and move the processed crop to a harvested crop repository, and a control system configured to identify a weed seed area indicating presence of weed seeds, and generate a control signal associated with a pre-emergence weed seed treatment operation based on the identified weed seed area.

Methods and systems for controlling robotic actions for agricultural tasks are disclosed which use a spacing-aware plant detection model. A disclosed method, in which all steps are computer-implemented, includes receiving, using an imager moving along a crop row, at least one image of at least a portion of the crop row. The method also includes using the at least one image, a plant detection model, and an average inter-crop spacing for the crop row to generate an output from the plant detection model. The plant detection model is spacing aware in that the output of the plant detection model is altered or overridden based on the average inter-crop spacing. The method also includes outputting a control signal for the robotic action based on the output from the biased plant detection model. The method also includes conducting the robotic action for the agricultural task in response to the control signal.

An autonomous ground maintenance system comprising a vehicle comprising a chassis supported upon a ground surface by ground support members, a container supported by the chassis, the container defining a discharge outlet operable to disperse treating material held within the container to a target area of the ground surface, a gate adapted to selectively open and close the discharge outlet, a sensor adapted to identify the target area, and an electronic controller supported by the chassis, the controller being in communication with the sensor and the gate. The controller is adapted to position the chassis at a location proximate the target area such that the discharge outlet is capable of delivering the treating material to the target area and energize the gate to open the discharge outlet.

Weed seeds are destroyed in the chaff from a combine harvester by repeated high speed impacts caused by a rotor mounted in one of a pair of side by side housings which accelerate the discarded seeds into contact with stator bars at angularly spaced positions around the axis of the rotor. The stator bars are formed from bent sheet metal which are L-shaped or U-shaped in cross-section to define a first leg lying in a cylindrical surface surrounding the axis of the rotor and a second leg extending outwardly from the cylindrical surface connected to the first leg at an apex at a leading end of the first leg relative to the direction of rotation of the rotor. When U-shaped, the bars are symmetrical and can be reversed when the second leg is worn for extended life.

The present invention relates to a weeding mechanism (1) for an autonomous weeding vehicle, and a weeding vehicle including the weeding mechanism. The weeding mechanism comprises a first shaft (3), a second shaft (5) arranged spaced apart from the first shaft (3), a first sledge (7) linearly movable along the first shaft (3), a second sledge (9) linearly movable along the second shaft (5), first and second actuators (11, 13) arranged to independently move the first and second sledges (7, 9) along the first and second shafts (3, 5) respectively, a first arm (15) pivotably connected to the first sledge (7), a second arm (17) pivotably connected to the second sledge (9) and pivotably connected to the first arm (15), and a weeding tool (2) operatively connected to at least one of the first and second arms (15, 17).
