xvi Making Things Move

will be posted there, or you can search for “dustynrobots” on Thingiverse
(www.thingiverse.com), Ponoko (www.ponko.com), or Shapeways
(www.shapeways.com) for a full listing of everything I have posted.

Along with knowing how to use the Internet, I also expect you to have a working
vocabulary of geometry, trigonometry, and basic algebra skills. If you can solve for
the ? in the equation 2 × ? = 6, and know what sine, cosine, and tangent mean,
relax—that’s about as complicated as we’ll get in this book. You need to know what
words like diameter, circumference, tangent, and perpendicular mean. If any of your
knowledge in this area is a little rusty, do a quick search online to review.

What You Need to Have

Each project in the book has a shopping list of parts and tools, so you can pick and
choose what you need. However, if you want to get a head start, here are some
common tools that will serve you well (see Figure 1):
