This is super interesting! I read your post, and just as an idea: is it possible to have a drone recognize weeds AND spray selectively in real time (no GPS coordinates there). I suspect the drone should be a custom build⦠The major challenge I can think of is the weight of the herbicide (although some drones already have this functionality DJI MG1S 12) but one could devise a way so that the drone goes across the field and back and replenishes its stock with a moving reservoir that moves slowly across the fieldās border as the drone progresses through the field.
