In this chapter, we built a robot that consists of a pair of motors driven by a Raspberry Pi using a motor driver. The robot is also equipped with a camera module to aid steering the robot. It consists of two battery packs to power the Raspberry Pi Zero and motors, respectively. We will also upload a video of the robot's operation to this book's website.
