Designing Robust Robots Requires:
Logic
Process
Productive Originality Defining why ideas do or do not make sense
Thinking, visualizing, building and testing. Trading on the currency of being focused and working hard.
Creative success comes frommaking a commitment and making It work!
DesirePassion gets you through the hard parts of journey

The Great 8
Select the Best Ideas
Visualize the Ideas
Understand the Problem
Develop Ideas
Evaluate
Build and Test
Create Drawings
Integrate
Mix and Match the Steps, but Understand the Problem

Reduce Risk Factors
Time
The Duplicator
The Adaptive Designer
The Innovator
Risk Comparison with Respect to Knowledge and Time

The 5 Budgets Rule the Design Process
Time Budgets
Weight Budgets
There is never enough so use it wisely. Make GANNT CHARTS
You can’t do everything. Make smart choices about what your robot will do and how it will do it.
Money BudgetsNuff said.
![Page 6: Design Tips Navigational Aids for the Journey of Creation.](https://reader030.fdocuments.us/reader030/viewer/2022032721/56649e575503460f94b4f587/html5/thumbnails/6.jpg)
Knowledge BudgetsAt the start of the project cycle, trade some Time for Knowledge. Work within your knowledge budget.What you don’t know can and will hurt you!
Power BudgetsBig 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
The 5 Budgets Rule the Design Process

Problem
It’s the game…..smarty!
KNOW THE RULES!

Ask Essential Questions About the Game.
How can the game be won?
How can the game be lost?
These are good starter questions.There are thousands more
How long is a game?
How fast do I have to move to score?

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

Create Specifications
Maneuverable
Fast
4 Wheel Drive
Use Pneumatics to Lift Opponents
Differential Steering
What does your machine have to do to play?
Clearly describe what your robot will do and be

Know WHAT your Robot will do
Know HOW your Robot will do it.
Before You Build
Recognize design trade-offsTime/Money/Knowledge/Power/Weight
Anticipate problemsStudy Mechanisms and Materials
Build and Test Assemblies

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.

Visualize the Prize
Use CAD Skills to Parallel the Prototyping Process
Make Sketches of the Ideas
Combine and Analyze the Ideas

Develop Multiple Solutions
Play the solutions against each other using “What if”
scenarios
Search for the best solution, then make it better

Build Test and Evaluate
Build a Drive Train and Test ItBuild things that work, and work and work
Make a Controllable PlatformPut 100 lbs on it
Test and Evaluate the Sub-AssembliesMake modifications and changes

Do the Math
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
(W/H) x CD-10 = Your Machine
