Chapter 2: Your Boe-Bot’s Servo Motors
This chapter will guide you through connecting, adjusting, and testing the Boe-Bot’s
motors. In order to do that, you will need to understand certain PBASIC commands and
programming techniques that will control the direction, speed, and duration of servo
motions. Therefore, Activities #1, #2, and #5 will introduce you to these programming
tools, and then Activities #3, #4, and #6 will show you how to apply them to the servos.
Since precise servo control is key to the Boe-Bot’s performance, completing these
activities before mounting the servos into the Boe-Bot chassis is both important and
necessary!
INTRODUCING THE CONTINUOUS ROTATION SERVO
The Parallax Continuous Rotation servos shown in Figure 2-1 are the motors that will
make the Boe-Bot’s wheels turn. This figure points out the servos’ external parts. Many
of these parts will be referred to as you go through the instructions in this and the next
chapter.
