  1. Automated Spray Patternator Team 14 Kevin M. Agnew Greg Barber David Rubin

  2. Progress Review • Project Description • Customers • Constraints • Wants • Approach • Benchmarks • Metrics • Concepts • Division of Labor/Schedule

  3. Mission Statement To develop and test an automatic spray patternator with high accuracy, improved resolution, a minimal amount of human error, test reset time, and allowing superior flexibility.

  4. Problem • DuPont finds its current Spray Patternator to be an inadequate design due to: • Low Accuracy • Human Error • Insufficient Resolution • High Reset Times

  5. Prioritized Customer List • Dupont Agricultural Research Team • Larry Gaultney • Ted Lang • James Davis • Mike Ceballos (Spray Systems Co.) • George Wicks • Dr. Leonard Schwartz • Dan Coppens (Anholt Technologies Inc.) • Joseph Buckley (Cherry Hill Mercedes)

  6. 54” Door Width Safety Guidelines (OSHA) Senior Design Project Schedule Budget Constraints

  7. 1. Provide All Desired Outputs 2. Automated Data Collection System 3. Observe interaction of 2 or more Nozzles 4. Comply with Hardware/Software Standards 5. High Accuracy and Resolution 6. Run on Tap Water 7. Be able to test 110° nozzles 8. Modular Design 9. Accurately Locate Nozzle Position 10. Mobile with in Lab Top 10 Prioritized Wants

  8. System Benchmarks • Current DuPont Spray Patternator • Hardi Inc. Field Patternator • Transportable Spray Patternator (Patent)

  9. System Benchmarks • Hardi Inc. Water Sensitive Paper • Hardi Inc. Laboratory Patternator • Spray Systems Co. Laboratory Patternator • Transient Spray Patternator (Patent)
