The concept of Integrated Pest Management has been around for several decades, and is just as useful in a robotic, no-till scenario as it is combined with conventional, traction-based agriculture, perhaps even more so. In a nutshell, it’s about the inclusion of biological controls in a mix of methods that can also include mechanical and chemical controls. The use of barn owls in this video is an excellent example.
They’re using radio-controlled aircraft rather than autonomous machines, but it’s still a big improvement over the time spent walking fields or the lack of detail that comes from only checking the edges of a field. I expect further improvements with the introduction of better sensors and on-board controllers.
