  1. Mechanical Engineering 151 Introduction to Mechanical Engineering II Dr. Eric Wang January 24, 2000

  2. Teaching Staff • Skills Lab Instructor • Steve McGahn • Teaching Assistant • Mr. Hy Ngu • Undergraduate Design Fellow • Mr. Neil Gavrich

  3. Course Goals • Creative thinking (innovation) • Engineering Graphics • Structured Programming • The Design Process • Self Learning • Team skills • Practice “Designing Things”

  4. Outline • Engineering Design • Course overview • Projects • The Student Contract • How to get help

  5. What is Engineering? From: C.L. Dym, Harvey Mudd College • What is an Engineer? One who is ingenious at devising (Latin) • What is Engineering? Process or product of being ingenious at devising

  6. What is Engineering Design? • Engineering design is: the systematic, intelligent generation, and evaluation of specifications for artifacts whose form and function achieve stated objectives and satisfy specified constraints.

  7. Engineering Design • The purpose and motivation for engaging in engineering design are (real or perceived) human needs. • The outcome of the design process (sometimes referred to the Product Realization Process) is often fabrication specifications, and the creation and production of a physical artifact. • Engineering artifacts range from hydro-electric dams to space shuttles to new packaging systems for instant soup.

  8. Engineer Designer Qualities From: Sheppard and Jenison, 1997 • Communicate, negotiate, and persuade • Work effectively in a team • Engage in self-evaluation and reflection • Utilize graphical and visual representations and thinking • Exercise creative and intuitive instincts • Find information and use a variety of resources (i.e. resourcefulness)

  9. Designer Qualities (cont.) • Identify critical technology and approaches • Use of analysis in support of synthesis • Appropriately model the physical world with mathematics • Consider economic, social, and environmental aspects of a problem • Think with a systems orientation

  10. Designer Qualities (cont.) • Define and formulate an open-ended and/or under-defined problem • Generate and evaluate alternative solutions • Use a systematic, modern, step-by-step problem solving approach • Build up real hardware to prototype ideas • Troubleshoot and test hardware

  11. Materials/Texts • Required: • Pro/ENGINEER: The Basics, McGahn (available in ME office) • Lego Technics Kit # 9747: Minstorms RIS 1.5 • References: • Lifeskills and Leadership for Engineers, Goldberg • Dave Baum's Definitive Guide to LEGO Mindstorms, Balm and Zurcher • The Unofficial Guide to LEGO MINDSTORMS Robots, Knudsen

  12. Yes, LEGO Each team must purchase one Mindstorms Kit

  13. Outline • Engineering Design • Course overview • Projects • The Student Contract • How to get help

  14. Course Components Sec. 1 Sec. 2 Projects lab Skills Lab(SEM 231C) M 2:30-5:30 Th 3:30-5 M 2:30-5:30 W 3:30-5

  15. Skills LabSection 1: Wed - 3:30 - 5:00Section 2: Thurs - 3:30 - 5:00 • Pro/Engineer •  9 assignments • Due at start • of class • 40% of total grade (400 pts)

  16. Projects Lab(mon 2:30 – 5:30) • Creative thinking exercises • Mini Design Projects (LEGO) • Teams • Technical writing • 9 “projects” • 50% of total grade (500 pts) • Transferable Points (Currency) • Sub-contract other teams

  17. Projects • Brainstorming • Creative Thinking • LEGO Design projects • LEGO Robot Competition

  18. LEGO Mindstorms

  19. LEGO Mindstorms RIS 1.5 • Controller (RCX) • Motors • light sensor • touch sensors • programming language

  20. LEGO Design Projects • Given Specifications & Constraints • Mindstorms RCX & Sensors Only • In-class & take-home projects • Performance Based Grading

  21. Outline • Engineering Design • Course overview • Projects • The Student Contract • How to get help

  22. Student Contract • Course format • Course objectives • Teams & responsibilities • Performance evaluations • Grading policy

  23. Teams & Responsibilities • Assigned to teams • Same grade • Each Team Member: • Demonstrate writing, speaking, & graphics • Actively participate • understand of all parts of the product • Respect

  24. Performance Evaluation • Peer evaluation form • Performance Review

  25. Performance Review • Requested by Team Member or TA • for conduct or performance • Deduct points • probation • Re-review • switch teams • eject from course

  26. Merit Pay • 10% of total grade (100 pts) • Incentive Based System • 20% of Team Grade in Merit Pay • Teams Distribute Merit • Peer Evaluations twice during semester Example: Project Score = 125 pts 125 x 20% = 25 pts x 3 team members = 75 pts

  27. Grading Policy Skills Lab Projects Lab Merit Pay Total 400 500 (transferable) 100 1,000

  28. Grading Scale A 90 - 100% b 80 - 89% c 70 - 79% d 60 - 69% f < 60%
