Our new FIRST Tech Challenge control system requires that your Driver Station (DS) device be �paired� with your Robot Controller (RC) device.  The FTC apps use Wi-Fi Direct technology to establish this connection between the two devices. If you are having problems pairing your devices, here are some tips: 1.   Make sure you pair the devices using the FTC Driver Station app .    Users should not try to pair the devices from the Android Wi-Fi Direct screen.   Instead they should use the Settings->Pair with Robot Controller screen on the FTC Driver Station App.      2. Make sure your devices are not connected to any other wireless networks.        If you are having difficulty pairing your devices, make sure your devices are not connected to any other Wi-Fi or Wi-Fi Direct networks.   You can use the Android Wi-Fi and Wi-Fi Direct screens to forget any �remembered� groups, then restart the devices and reattempt the pairing...

The Modern Robotics (MR) Core Power Distribution Module (PDM) and the 12V 3000mAh battery are equipped with Tamiya electrical connectors. The PDM�s power input cable has a male Tamiya connector and the 12V battery has a female Tamiya connector.        Figure 1 - The PDM and the 12V Battery have Tamiya electrical connectors. The Tamiya connector is a common type of connector often used in the RC model industry. The Tamiya connector is a keyed type of electrical connector. This means that the shape of the connector prevents a user from improperly connecting two electrical components together. For the PDM, the square shaped component of the Tamiya connector matches the square shaped (positive) receptacle on the battery�s female Tamiya connector. The PDM�s circular shaped component matches the circular shaped (negative) receptacle on battery�s female Tamiya connector. The Tamiya connectors work well, but the internal components can stretch and loosen after repeate...
