How to Get Through 2.007
(and learn a bitand maybe win if you really want to)

First off
Do not be daunted by the tasks ahead! This class is about learning the design process, how to
manufacture, how to communicate, how to design, etc. We wont leave you in the dark!
Dont worry if youve never done anything like this before! I was totally new to the design process and had barely
done any machining when I started 2.007.

How to Get Started(Hint: the next ~14 slides model your first Milestone)
First, figure out what you want to do! (your class objective)
Want to win? Want to make a cool robot? Want to pass the class?
Mark Cote 2006
2.007 Design and Manufacturing2.007 Design and Manufacturing
Strategy Time
Next, come up with some strategies based upon what you want to do
(think FR-DP) What you want to do How youre going to do it
Be detailed a strategy should summarize what you plan on doing in the competition (make a 45 second timeline)
Dont think about concepts yet! The design process starts with good strategies
Strategies YES, plural brainstorming is NOT synonymous with being close-minded (make 3-5)

Quick Note
Even though your first idea might end up being your final machine, Brainstorm!!! Think creatively! Sometimes the craziest ideas inspire the
most innovative, clever solutions Parts of a few different strategies (or
concepts later on) will form your final one
More on this at the end (pics/videos!)

Developing Strategies(think FRDPARRC)
Scoring Gathering balls Transporting them Scoring them
Offense Mess with the other
robot
Defense Protect your
robot/balls/scoring area
Mark Cote 2006

Functional Requirements (What?)
Example: I want to score four
engineering balls and the grad ball in the A-slot and will block my opponent after.
Mark Cote 2006
2.007 Design and Manufacturing2.007 Design and Manufacturing
Design Parameters (How?)
I screwed up my first milestone soHow for this is How would I do this?
Good Example: I will pick up the balls with a grabber,transport them in a corral, line up my machine with the A-slot, and drop them in.
Bad Example: I will use a four-bar linkage lever-winch system to pick up 5 engineering balls in a line, deposit them in a U-shaped corral atop my robots base, and using a leadscrew pushing mechanism will deposit them in the A-slot. TOO SPECIFIC FOR NOW Think broadly!

Sketches and Analysis
Show your idea on paper
Include a timeline,rough power budget (can your motors/battery do this?)
This will get more detailed later in the course
Mark Cote 2006
2.007 Design and Manufacturing2.007 Design and Manufacturing
Analysis (words and numbers)
Your analysis will end up fairly detailed and should include: Sketches Explanations Equations Power Budget Bench Level Experiments Proof of concept Theoretical, analytical, and real world proof

References
Never forget these! Give credit to the people who deserve
it! Saw it on the website In a book On a piece of machinery Discussion with a UA ALWAYS reference your lab notebook

Risks and Countermeasures
Heres your chance to over-analyze! These are physics problems, difficult
engineering steps, concept issues, vulnerabilities in strategies, etc.
Come up with specific problems and give good solutions Not: Design it well so it works
Mark Cote 2006
2.007 Design and Manufacturing2.007 Design and Manufacturing
Example Risks and CMs-car is unstable around ramps; hard to maneuver
-make a suspension system (complex!)-smaller wheelbase-change drive wheel layout-practice driving
-car is too slow -decrease gear ratio-decrease car body friction with the carpet
-car wheels spin out -add sandpaper to the wheels
-cant finish design on time/problems hold up production
-make a bulldozer car to just push balls around and hopefully score
-cant score in A-slot because of driving difficulty
-slow down gear ratio-practice-design a mechanical stop so the car lines up at A-slot

Thats a FRDPARRC!
When you do these, make them detailed and extensive Should be able to explain your
organized ideas to anyone even someone who has a vague idea of the competition
Should include any and all relevant analysis to prove that you can do what you propose

The 2 Forms of 2.007
Logistics and Grades
The Competition
Mark Cote 2006
2.007 Design and Manufacturing2.007 Design and Manufacturing
Logistics and Grades(How to Get an A)
Go to lab! WRITE EVERYTHING YOU THINK OF IN YOUR LAB
NOTEBOOK Organize your Milestones
Think of Milestones as a summary of all of your thinking Your TA should be able to figure out basically all of your thoughts just by looking at
these few pages
Be creative! Creativity spawns innovation
Model your machine (2D and 3D) This makes it so much easier to fabricate
Talk with your TA Theyre the ones grading so show them you care about the design process and your
learning
Mark Cote 2006
2.007 Design and Manufacturing2.007 Design and Manufacturing
The Competition(How to Do Well and Maybe Even Win!)
Make a Robust Design Great versatility and performance against any type of
opponent
Design with the table in mind Do not assume anything
Check if you have a question Do a BLE if you arent sure about something
Make a schedule (early like now) and stick to it
Build in a 3-4 week buffer Think about product engineering lots to do after
theres a prototype
Mark Cote 2006
2.007 Design and Manufacturing2.007 Design and Manufacturing
The Competition(2 of 2)
Finish early and practice a ton Make your robot intuitive
Driving should make sense and be fairly easy to learn
Fix things that could break before they break (especially in the last week)
Dont waste time in lab especially early on Do all the out of lab stuff that you can out of lab
Design, strategize, drill holes (you have a nice drill) Lab is for fabrication, testing, modification, and discussion
with TAs and UAs

The Competition Secrets(If you want to win)
Build a machine the practically drives itself Be ambitious (see pics/videos) Be realistic
You have to build it!!! Find your inner engineers nirvana
Learn to focus winning the competition is 30% robot (you need this though), 20% driving, and 50% mental
Get Lucky (just a bit)

3 Quick Things to Remember
1. Keep it simple! robust designs are versatile! you have to build what you dream up!
2. Write everything down in your design notebook
And I mean everything! It doesnt need to be ridiculously organized but get your ideas on paper!
Taking pictures is a good idea document the process or designing/building your robot
3. Talk with people! Other students, UAs, TAs, profs, the lab guys,
previous students you can learn a ton from people who have been through .007
