CHAPTER 6 ■ ROBOT LINE-FOLLOWINGOf course, you still have the option of modifying the kit as desired, by substituting your own parts or
decorations. In any case, you will need to supply a piece of plastic or container to hold the robot together.
Building Up
You should now understand the line-following course requirements and the basic functional anatomy of
Sandwich.
If you haven’t soldered, drilled, or worked with electronics before, it may seem like a huge leap to get
from here to actually building the robot. Don’t distress. The coming chapters break down each element,
telling you what to buy, how to test, and how to prototype the line-following circuit.
Even if you’ve decided you don’t want to build a line-following robot, please read the next chapters
carefully. Although Sandwich forms the framework for each topic, the subject matter and techniques taught
are applicable to all robots.
