Abstract:
A method for weeding crops includes, at an autonomous machine: recording an image at the front of the autonomous machine; detecting a target plant and calculating an opening location for the target plant longitudinally offset and laterally aligned with the location of the first target plant; driving a weeding module to laterally align with the opening location; tracking the opening location relative to a longitudinal reference position of the weeding module; when the weeding module longitudinally aligns with the first opening location, actuating the blades of the first weeding module to an open position; recording an image proximal to the weeding module; and in response to detecting the blades of the weeding module in the open position: calculating an offset between the opening location and a reference position of the weeding module, based on the image; and updating successive opening locations calculated by the autonomous machine based on the offset.
