Title: Developing Models and Prototypes (Steps and Decision Making)

1
Chapter 6
• Developing Models and Prototypes (Steps and
Decision Making)

2
Chapters Sections
• Value of Modeling
• Selecting Modeling Process
• Performing Design Analysis
• Testing and Reviewing a Design

3
Why Engineers Use Modeling?
• To develop a better understanding of the design
problem/possible solution
• To save time and money
• To reach an optimal working solution by refining
design ideas
• To convey ideas and information

4
What are the modeling steps?
1. Selecting a modeling process
2. Performing design analysis of aspects and parts
3. Performing integration testing
4. Revising, refining and critiquing the design

6.1 Selecting a Modeling Process
• Descriptive models sketches models
• Predictive models maths logic
• Scale models
• Geometrical modeling
• wireframe model
• surface model
• solid models model
• Mathematical modeling
• Computer simulation
• Computer animation

6.2 Performing Design Analysis
• Evaluating the sufficiency of a design
• for Autonomous Robot
• Overall algorithm can be simulated
• Body must be rigid and maneuverable
• Various functionalities must be tested
• Speed of robot must satisfy constraint
• Functionality of sensors relative to detectable
objects
• Recovery from errors must be investigated

6.3 Testing The Overall Design
• Testing the integrated overall design
• Making sure that all parts work together
• Then ..

6.4 Revising, Refining and Critiquing The
Design
• By someone other than the original designer
• To avoid ..
• This is my baby syndrome!

16
In Summary
• Modeling is a valuable pursuit that allows all
kinds of analyses (e.g. functional, aesthetic,
financial)
• Various parts and aspects of a design can be
modeled, for
• the purpose of improving and optimizing the
design.
• Integration testing must not be overlooked.
• Its best if the task of designing and of
critiquing are separated
