Wiring up the robot
With the robot built and the electronic components attached, it is time to wire it up! The importance of good wiring of a robot is an often-overlooked part of a robot build, but it is critical to your robot’s reliability. Figure 12.6 gives you an overview of the complete wiring that we will discuss in detail in the following paragraphs:
