CAD on your team
Do you make CAD models at all? If so, what is it used for? Just documenting
the design that you already built? Or, do you actually design parts of your
robot before you build it?

Why use CAD for Design?
You can avoid problems before they happen Too heavy Dimensions are too big Mechanisms don’t work as you thought they
would Components are “in the way” that nobody
realized until you tried it out It’s cheaper to model in software than in
hardware Parts list for purchasing This is how real businesses design stuff You can make really cool
marketing/documentation as well

But, it’s too hard to model the whole robot – that would take forever!
Don’t model the whole thing Only design the parts that are critical to success, or that
you have concerns about If you are re-using the drive train from last year, don’t model
that, just model the parts that are critical to the game Don’t model in too much detail
Tire treads are not necessary for analyzing your design Use the internet
There is a lot of designs out there that you can use GrabCAD FIRST Parts manufacturers
Divide up the design among multiple team members

Using Fusion360 for your designs
What is Autodesk Fusion360? Cloud-based CAD for collaboration Direct modeling and a simple, modern UI Runs on Windows and Mac Support for mechanical joints to make
mechanism design simple Fusion (and all Autodesk software) is free
for students

Collaboration with a team You don’t have to share computers or thumb
drives to have multiple team members work on the same design
Even a single team member can work on the design at school, at home, anywhere.
Mechanism design Fusion’s Joint command allows you to create
mechanisms very quickly Motion Link and Motion Study
Fusion 360 features of interest:

Interference detection Can determine if parts collide Contact sets also useful for this
Mass properties Can show overall weight, volume, center of
gravity
