This tutorial is focused on changing the Wi-Fi settings for a classroom setting. Those participating in FTC, FGC, or another competition should check the latest game manual for rules on device names.
Version 10.2 and newer of the Driver Station App/Robot Controller App now shows a warning if the names used on the Control Hub and Driver Hub do not match the current FTC rules. This is a cosmetic warning that does not prevent normal operation.
Navigate to the Control Hub in the REV Hardware Client. If currently viewing a different device, click Hardware to return to the home screen.
Select the Program and Manage tab once in the Control Hub's menus.
This menu contains the options for programming as well, but for now click on the Manage option.
Here you'll find all the options for updating the Wi-Fi settings. For now we will focus only on the name and password. It's recommended to give each Control Hub an easily recognizable name.
This might be a group name, student names, a color, a number, or similar that fits your classroom needs for assigning robots. This is the name that will be displayed in the REV Hardware Client and as the network to connect to later using the Driver Hub.
The default password is password. Consider allowing student groups to pick their own password to secure their robot. If the password is forgotten, it can be changed here again later.
Click Apply Wi-Fi Settings once all changes have been made. The Wi-Fi Band settings can be left on the default (5 Ghz and auto Wi-Fi Channel) for most classroom environments.
The files on the Control Hub can be backed up using the REV Hardware Client. Remember all programming files and configurations are stored directly on the Control Hub so it is good to regularly back it up!
Select Backup/Restore
Select Backup Files
The saved zip file's name will appear after the backup runs. Click this to open the file location.
It's recommended to move this zip to an easy to find location, such as Documents.
Setting up the DUO Control System for the first time can be broken into 4 steps:
Powering Up
Updating
Managing settings
Connecting the Driver Hub to the Control Hub
Before getting started you will need:
From the kit:
Additional items:
The Control Hub is powered with a 12V Slim Battery. The battery connects to the yellow XT30 port labeled as "Battery".
When first powering on, the light on the Control Hub will illuminate blue then change to green when fully booted.
At this point it's ready for use!
To power on the Driver Hub, hold the power button for a couple seconds until the REV logo appears on the screen. During boot up, a white light will flash and the green light beside the power button will appear.
The Driver Hub will take a few moments to reach the lock screen. The white light will no longer illuminate.
If this is the first time powering on the Driver Hub, the set up screen will appear.
When the Driver Hub is first powered up, or a factory reset is performed, an initial set up process is needed. Start by selecting next on the main screen to continue.
For now, it's recommended to skip the step connecting the Driver Hub to a local Wi-Fi network.
On the next screen, set the date and time before continuing.
Initial set up is complete! Select Finish to go to the Driver Hub's homescreen.
Connect the Control Hub to the Windows computer using the orange USB cable that came with the Control Hub. The USB-C (oval) side connects to the Control Hub while the USB-A (rectangle) connects to the PC.
A different cable, or USB C-to-C cable may be used but MUST be able to do both power and data. Note: Some generic cables only do power.
Open the REV Hardware Client once connected. The Control Hub should appear on the home screen (Hardware tab).
Click on the Control Hub to open the update menu.
There are 3 options for items listed that may need updating:
Control Hub Operating System: This is the main software of the Control Hub. It receives rare updates, but likely will need updating upon first use.
Robot Controller App: This is the software tied to the Robot Controller Console that allows for programming the Control Hub and communication with the Driver Hub. This software updates most frequently!
Hub Firmware: This is the core firmware for the electronics of the Hub to function. It should be up to date on first use and receives very rare updates.
Once you are ready to update you can select "Update All to Latest Version". Be aware the first time updating may take some time depending on your network environment.
The Control Hub can remain connected or be unplugged while updating the Driver Hub next.
Connect the Driver Hub to the Windows computer using the orange USB cable that came with the device. This is the same kind of cable used for the Control Hub.
The USB-C (oval) end connects to the Driver Hub and USB-A (rectangle) end connects to the computer. Once connected, the Driver Hub will appear in the REV Hardware Client similar to the Control Hub.
Clicking the Driver Hub will open the Update menu.
There are two types of software available for updating on the Driver Hub:
Driver Hub Operating System: This is the core Android OS that runs on the Driver Hub. It receives occasional updates and may require updating on first boot up.
Driver Station App: This allows the Driver Hub to communicate with the Control Hub. This app and the Robot Controller App always receive updates at the same time.
Once you are ready to update you can select "Update". Be aware the first time updating may take some time depending on your network environment.
Switch Cable (Recommended)
Locations with restricted internet access, such as a school with a firewall/web filtering, may experience trouble installing the REV Hardware Client or updating devices. Please contact your IT for assistance.
If it's not already open, tap the Driver Station Application on the home screen of the Driver Hub to open it.
Look for the 3 dots in the upper right hand corner of the Driver Station Application to tap open the menu.
In the dropdown menu, select Settings.
Select Pair with Robot Controller
Select Wi-Fi Settings.
From the list of Wi-Fi networks, look for the Control Hub's assigned name that was decided during the last step of set up.
Enter the password to the Wi-Fi network in the password field that was decided during the last step of set up. Then press CONNECT.
Press the back arrow at the bottom of the display until you return to the main driver station screen.
After a couple of seconds, the Driver Station page will indicate the network name, a ping time, and battery voltage. The robot may appear to restart (sound effect will play) before finalizing the connection.
Your Driver Hub is now paired with your Control Hub!
The Driver Station Application allows for the connection of two gamepads. When working with the Driver Hub these gamepads can be plugged into any of the three USB 2.0 ports. Once the gamepads are plugged in, you will need to initialize them.
To initialize the gamepad that will act as User 1 (gamepad1, in code) press the options button and the Xbutton on the gamepad at the same time. To initialize User 2 ( gamepad2, in code) press the options button and the O button at the same time.
The EDU Kit V2 includes a REV USB PS4 Compatible Gamepad. For the Logitech F310 Gaming Controller and Xbox 360 Controller for Windows, press start and A at the same time to initialize User 1 and start and B at the same time to initialize User 2.
