-This section explains how to connect a motor, a servo, and a sensor to your REV Robotics Control Hub or REV Robotics Expansion Hub.  While the Control Hub differs from the Expansion Hub because of its built in Android device, the layout of the external motor, servo, and sensor ports are identical for the Control Hub and Expansion Hub.
+This section explains how to connect a motor, a servo, and some sensors to your REV Robotics Control Hub or REV Robotics Expansion Hub.  While the Control Hub differs from the Expansion Hub because of its built in Android device, the layout of the external motor, servo, and sensor ports are identical for the Control Hub and Expansion Hub.
 
 The images in this section use an Expansion Hub to demonstrate how to connect the devices.  The process is identical for a Control Hub.
