Introduction
Robots are made up of mechanical structures and the electrical components that move and control them. Electronics is a
broad category which includes motors, sensors, and programmable controllers or hubs. The REV Robotics Building
System has two kinds of Hubs: Control Hub and the Expansion Hub (Figure 1). The Control Hub has an integrated
computer module running Android and is where the robot code runs, while the Expansion Hub only provides a break out of
additional ports. Please note that every robot must have one Control Hub, but adding an Expansion Hub is optional.
