The AGCO SCOPE team developed a smart rinse verification system for a post-emergent agricultural sprayer. When spraying a field, an operator must switch between chemicals to adjust for different plant conditions and types of crops. Due to the nature of the chemicals used, the system must be completely rinsed to remove all traces of the old chemicals before new ones are used. If the sprayer is not fully rinsed, the chemical residue remaining in the system may harm the new crop. Through research, ideation, design, and fabrication, the Olin team built a prototype system that provides feedback to the operator regarding when it is safe to proceed with loading the new solution.
