Thoughts on the Design Process
Navigational Aids for the Journey of Creation
3
The Journey of Creation is About
Productive Originality
Create a successful BattleBot by making a
commitment and making it happen
Logic
Understand why ideas do or do not make sense
Process
Thinking, visualizing, building and testing.
Trading on the currency of being focused and
working hard.
Desire
Passion gets you through the hard parts of journey
4
The Great 8
Mix and Match the Steps, but Understand the
Problem
Create Drawings
Integrate
Build and Test
5
The 5 Budgets Rule the Design Process
Time Budgets
There is never enough so use it wisely.
Money Budgets
Nuff said.
Weight Budgets
You cant do everything. Make smart choices about
what your robot will do and how it will do it.
6
The 5 Budgets Rule the Design Process
Knowledge Budgets At the start of the project
cycle, trade some Time for Knowledge. Work within
your knowledge budget.What you dont know can and
will hurt you!
Power Budgets Big motors, high speed and
torturous torque curves need big batteries. Big
batteries impinge on weight budgets. You have to
run hard for 3-5 minutes.
7
Understand the Problem
Its the game..smarty!
KNOW THE RULES!
8
Know the GAME
3D Studio Max 4
Talk about the game.a lot.
9
Ask Essential Questions About the Game.
How can the game be won?
How can the game be lost?
How fast do I have to move to score?
How long is a game?
These are good starter questions. There are
thousands more
10
Brainstorming is About Developing Ideas
Develop and Share Ideas
Lots of Ideas
11
Make Statements About the BattleBot
Write 100 things about the robot, write them,
write them on a plane, write them, write them on
a train, write them, write them until you go
insane!
Copy them in your design notebook
12
Develop Multiple Solutions
13
Create Specifications
Clearly describe what your robot will do and be
Use Pneumatics to Lift Opponents
Maneuverable
Fast
4 Wheel Drive
Differential Steering
What does your machine have to do to play?
14
Before You Build
Know WHAT your Robot will do
Recognize design trade-offs Time/Money/Knowledge/P
ower/Weight
Know HOW your Robot will do it.
Anticipate problems Study Mechanisms and
Materials Build and Test Assemblies
15
What comes first.
These are not questions
What comes before How
16
Ask Essential Questions About the Stuff You Need
to Build a BattleBot.
How do I make wheels and axles move?
How much power can the motors produce?
Think of a few hundred more.
17
Visualize the Prize
Combine and Analyze the Ideas
Make Sketches of the Ideas
Use CAD Skills to Parallel the Prototyping
Process
Build Models of the Idea
18
Build Test and Evaluate
Build a Drive Train and Test It Build things
that work, and work and work
Make a Controllable Platform Put 100 lbs on it
Test and Evaluate the Sub-Assemblies Make
modifications and changes
19
Make a Decision Matrix
Compare Ideas Rationally
4 Wheel Drive
2 Wheel Drive
Time Money Knowledge Power Weight
2 2 2 1 2
1 1 1 2 1

Two wheels have advantages with respect to the 5
Budgets
20
Do the Math
(W/H) x CD-10 Your Machine
W WHAT you want the machine to do
H HOW you expect the machine to do it
CD-10 What the machine CAN DO given
the available time and resources
21
Simple is Often Elegant
E mc2
Good designers understand the power of simple
elegance
22
Use the BBIQ Table Top Prototyping Kit To
Model Ideas
Combine Components
Integrate Assemblies
Test Concepts
23
Model It Test It Evaluate It
Refine the Design
Build It
24
Think
Modify
Build
Test
Evaluate
25
Refine the Design
Deliver a Working Robot on Game Day
Win the Crowd Maximus.

Play with the BattleBot
Take the Time To Make Your Bot Beautiful
You worked for this, enjoy the games
