1 Sweet Cherry Mechanical Harvest Technology Research at WSU Prof. Qin Zhang Center for Precision & Automated Agricultural Systems Washington State University 2012 International Mechanical Harvest Symposium

2 WSU CPAAS: An Overview The Center for Precision and Automated Agricultural Systems (CPAAS) was established in Offer an integrated framework for automated and precision agriculture efforts at WSU. Currently put a strong emphasis on specialty crop related research, including mechanical harvest

3 CPAAS: Trans-disciplinary Research Information Sciences Economic Sciences Biological Sciences Growing: Land preparation Planting/transplanting Pruning Thinning Managing: Water management Weeds management Pest management Disease management Harvesting: Maturity Non-selective harvest Selective harvest Traceability Post-harvesting: Safety Quality Transporting Traceability Engineering Sciences

4 Challenges in Mechanical Harvest 1.Orchard System: Machine compatibility 2.Need for crop load uniformity 3.Range of orchard systems 4.Market size 5.Assist systems do not replace large numbers of employees 6.Capital investment required WSU CPAAS, collaborating closely with industry, is developing a roadmap to develop mechanized fruit harvest systems. The near future focus - will be on fruit removal from the tree and transport the removed fruits to the bin.
