Weed control can be tricky because we want to protect crops and biodiversity at the same time. Scientists studied how robots can help with weeding while keeping both goals in mind. They found that robots need detailed information about different weed species and their competitiveness to maintain biodiversity. Robots must be able to identify and remove specific weeds to be effective. The success of this strategy doesn't depend on how varied crop yields are or how many weed species are present.
