An Engineering Challenge(some material excerpted from John V-Neun’s 2009 presentation)

• Functional Requirements• Goals and objectives

• Constraints• Physical (dimensions, weight)• Time• Money

• Tradeoffs

The Engineering Process

1. Define the problem• Make sure it’s the right problem!

2. Generate specifications• Use the requirements and the constraints

3. Set priorities

4. Design concepts• Brainstorming

The Engineering Process

5. Prototype• Goal is to learn

6. Choice• Every choice results in some loss

7. Detailed Design8. Build!9. Document

The Engineering Process for FIRST

• Design• Discuss concepts and Prototype• Analyze and Adjust your design• Prototype…:• Detailed Design• Manufacture

The process is iterative.

Week 1 - Let’s Just Build!

But now…• Robot is too heavy• It’s too big• The parts don’t fit in the allocated space• Too fragile• Not easily fixable• Doesn’t perform the task well• Rework; waste resources

Week 6 - I wish I had designed

FRC Engineering awards and criteriaAward Criteria

Excellence in Engineering Award

• Elegant and Innovative machine feature that has real world application.

• Design, wiring, material, programming, unique machine attribute• Verbally describe the concept, design, manufacturing/assembly and

deployment• Works well in competition. Extraordinarily cerative, functional, practical

Innovation in Control • Innovative control system or application of control components to provide unique machine functions.

• Verbally identify and describe the feature• Demonstrated to judges or in field of play. Not just a cute idea - it

must work and be reliable in the stress of competition

Creativity • Creative design• Creative use of a component• Creative playing strategy• Verbally describe the unique/creative feature. • Highly original in concept• Practical• Engineered, not discovered by accident
