  1. Team 25Define PhaseSemi-Autonomous Palm Harvester

  2. Team Organization Ricardo

  3. Sponsor Dr. okenwaokoli • Ph.D., University of Warwick, 1996 • Current chair of the Department of Industrial & Manufacturing Engineering • Research Interests include • Composite manufacturing • Metallurgic properties of casting Ricardo

  4. Advisors Dr. David Olawale Dr. Jonathan Clark • Ph.D. Industrial & Manufacturing Engineering, Florida State University, 2011 • Research interests • Structural Health Monitoring • Multifunctional Composites • Ph.D. Mechanical Engineering, Stanford University, 2004 • Assistant Professor • Research interests • Robotics - legged locomotion • Dynamic system analysis • Mechanical design and fabrication Ricardo

  5. What is an Oil Palm? • Elaeisguineensis • Typically grown within 20° of equator • Trees can grow up to 20m tall • Plantation trees usually cut around 12m • Oil extracted from fruit pulp and kernel • High oil yield crop • Common cooking ingredient in SE Asia and tropical belt of Africa • Potential use in biofuels Ricardo

  6. Project Definition • Background Research • Project Scope • Assumptions • Project Deliverables David

  7. Background Research David

  8. David

  9. Background Research David

  10. Background Research • Safety issues • Current climbing methods are risky and dangerous • Goal is to replace the climbing methods with a safer alternative David

  11. Background Research Affordability quote • Expensive business • Keep labor costs down • Potential clients won’t buy complicated product • Won’t buy expensive product “Oil palm planters, including smallholders, will bleed red ink if palm oil prices were to dip below RM2,000 per ton, said Malayan Agricultural Producers Association (Mapa). Many of our planters borrow money from banks and issue bonds. If palm oil prices were to fall further, some planters may face difficulties in repaying the banks.”(Btimes) David

  12. Background Research Oil Palm Plantation Rainforest • Environmental impact • PRO: Palm Oil can be used for biofuel • CON: Plantations displace rainforests David

  13. Background Research • Customers • Plantation owners • Plantation workers • Service companies David

  14. Project Scope • Goal • Construct semi-autonomous oil palm harvesting machine • Budget • $2,000 • Considerations • Safety • Affordability • Efficiency • Reliability David

  15. Assumptions • Tree specifications are as previously defined • Climate • Assuming tropical climate with a lot of rainfall • Harvesting plantations • Trees spaced in triangular pattern 9m apart • Potential customers • Clients will not buy an expensive product David

  16. Team Deliverables David

  17. Project Charter Business Case Opportunity Statement Needs Statement Louis

  18. Business Case • Need for an efficient harvesting method • Total global production of palm oil 45 million tons • Palm oil consumption ranges from cooking oil, margarine, soap, and detergent • Denmark, Switzerland and some U.S counties banned use of trans-fats • This presents an opportunity for vegetable oils such as palm oil Louis

  19. Business Case Potential output for oil palm production (In thousands of hectares) Louis

  20. Business Case Actual output is world share of palm oil Nigeria’s plantations can be utilized better Louis

  21. Opportunity Statement • Product opportunity • Consumption of vegetable oil went from 40 million tons to 130 million tons • Also, Belgian companies are investing in West and Central African countries’ plantations • Demand is going up for Palm Oil Louis

  22. Opportunity Statement • Oil Palms have highest return per area of all oil crops • Profits from plantations are • $960/ha for low-yield independent growers • $2,100/ha for supported growers • $2,340/ha for high yield independent growers • $3,340/ha for large scale growers Louis

  23. Review of Needs There exists a need for a safe, reliable method of harvesting This method should reduce cost of labor by requiring less work It should improve productivity Louis

  24. Analysis of Customer Requirements • Critical Customer Requirements (CCR) • Economic Analysis • Environmental Impact • Ethical Considerations • Health and Safety • Sustainability Gianni

  25. Voice of the Customer (VOC) Gianni

  27. Design Concepts • Previous Concept: Improve Previous Prototype • Concept 1: Treaded Robot • Concept 2: Cart with Extendable Pole • Concept 3:Modified Linkage • Decision Matrix Brian

  28. Previous Concept Improve Existing Prototype • Pros: • Already constructed • Cons: • Heavy: ~150 lbs • Slow:~10 minutes to climb tree • Incomplete electronics • Parts may be salvageable Brian

  29. Concept 1Treaded Robot Pros: • Can climb over rough surfaces • Fast and lightweight • Self-stabilizing Cons: • Mechanically and electrically complex • Difficult programming Brian

  30. Concept 2Cart with Extendable Pole Pros: • Very simple design • No complex programming • Easy maintenance Cons: • Less portable • More material cost Brian

  31. Concept 3Linkage climber Pros: • Has been proven to work on smooth trees • Small in size • Very fast Cons: • Somewhat complexmechanically • Likely to get stuck Brian

  32. Decision Matrix Cart with Extendable Pole wins Brian
