Control Systems¶
The FTC® control system is based around a “Robot Controller” and a “Driver Station”. The Robot Controller is mounted on the robot. It is either embedded within or connected to special “Hub(s)”, which in turn connect to motors, servos, and sensors. The Robot Controller is linked to the Driver Station through Wi-Fi or Wi-Fi Direct.
REV Robotics is the sole manufacturer of legal FTC control system components. The REV Expansion Hub connects to motors, servos, sensors, and a Robot Controller. A REV Control Hub has the same functionality of an Expansion Hub but with a built-in Robot Controller.
More information about the FTC Control System can be found below:
There are two possible control systems that can be run on an FTC robot legally:
REV Control Hub + REV Expansion Hub
RC Phone + REV Expansion Hub(s)
REV Control Hub + REV Expansion Hub¶
This is the standard control system for teams in FTC.
The Control Hub connects to the Expansion Hub through either a RS-485 connection, or a USB-A (Control Hub side) to USB Mini-B (Expansion Hub-side) connection. In either case, proper strain relief and cable management should be used.
For more information on setting up the Control Hub and configuring the robot, head to REV Robotics’ Technical Resources Control Hub Guide .
RC Phone + REV Expansion Hub(s)¶
The Expansion Hub connects to the Robot Controller phone through its USB Mini-B port. The REV Expansion Hub is reliable, as long as proper strain relief and wiring is carried out. This includes the USB Retention Mount, as well as 3D printing XT30 stress relief mounts.
