Researchers at Cornell University collaborated with colleagues from the University of Florida and Carnegie Mellon University to develop a precision sprayer retrofit compatible with an autonomous tractor as part of the Integrated Automation for Sustainable Specialty Crop Farming project (IASSCF) funded by the USDA. This case study examines how Cornell researchers planned and designed the retrofit. It includes results of a commercial citrus grower's needs assessment, a sprayer selection processes, a failure mode and effects analyses, a sprayer operations monitoring strategy and a canopy assessment that established manifold dedications and liquid flow requirements. An experimental design that evaluates the sprayers ability to maximize application coverage is also presented. This first-of-its-kind sprayer retrofit planning process provides insight into how sprayers will be designed for autonomous tractors in the near future.
