Design Tips
Navigational Aids for the Journey of Creation
3
Designing Robust Robots Requires
Productive Originality
Creative success comes from making a commitment
and making It work!
Logic
Defining 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
Reduce Risk Factors
6
The 5 Budgets Rule the Design Process
Time Budgets
There is never enough so use it wisely. Make
GANNT CHARTS
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.
7
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. Honor the
run time constraints! Analyze your battery and
motor combinations
8
Understand the Problem
Its the game..smarty!
KNOW THE RULES!
9
Know the GAME
And the Rules that Govern the Play
Trinity Fire Fighting
FIRST
BattleBots IQ
Texas Best
BotBall
Talk about the game.a lot.
10
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
11
Brainstorming is About Developing Ideas
Develop and Share Ideas
Lots of Ideas
12
Write Statements About the Bot
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
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 Bot.
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
18
Develop Multiple Solutions
Play the solutions against each other using What
if scenarios
Search for the best solution, then make it better
19
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
20
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
21
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
22
Simple is Often Elegant
E mc2
Good designers understand the power of simple
elegance
23
Combine Subassemblies
Integrate the Parts
24
Test It, Evaluate It
Refine the Design
25
Think
Modify
Build
Test
Evaluate
26
Refine the Design
Deliver a Working Robot on Game Day
Win the Crowd Maximus.

Play With the Bot and Learn to DRIVE
You worked for this, enjoy the games
