The American Society for Agricultural and Biosystems Engineers (ASABE) and the Association of Equipment Manufacturers (AEM) presented the inaugural Davidson Prize to three outstanding innovative products. One of those winning products is the Robovator Mechanical Weeding Machine, a project by University of Arizona ABE Professor, Dr. Mark Siemens, and UC Davis Extension, Specialist Dr. Steve Fennimore. Mark and Steve successfully secured funding from USDA NIFA in 2014 to evaluate and demonstrate robotic cultivators in vegetable crops. We found that one product Robovator reduced hand weeding time about 30% and removed as much as 85% of weeds from lettuce plantings. Today Robovator is commercialized and over a dozen are in commercial use. Richard Smith of the University of California Division of Natural Resources also deserves a lot of credit too for the advancement of automation in lettuce thinning and weeding in California vegetable crops.
