Robot Building for Beginners, Third Edition

CHAPTER 6 ■ ROBOT LINE-FOLLOWING

Don’t be fooled or overwhelmed by it. This robot breaks down into smaller modules that are easily
recreated. The next sections of this chapter describe the modules and switch functions.

Line-Following Switch

At the rear of the robot is a toggle switch (see Figure 6-9). This switch has three positions: left, center, and right.
