University of Florida researchers are designing a machine that can surgically eliminate weeds while preserving the tomatoes and peppers around them utilizing artificial intelligence (AI) and sensor fusion. Vinay Vijayakumar, a doctoral student working under the supervision of UF/IFAS Associate Professor Yiannis Ampatzidis, created the smart-spraying system that targets weeds on raised beds of soil and in row middles, the areas between rows of plastic beds.
