### Uploading a Custom Webcam Calibration File
The Robot Controller app has built-in calibration information for a variety of commonly available webcams. Users can also create their own custom calibration files and then upload these files to a Control Hub.
A commented example of what the contents of a calibration file should look like can be found in a file called teamwebcamcalibrations.xml, which is included with the FTC Android Studio project folder.
