Find me on the Google Play Store! under the name "FTC Neural Net Demo".
This app is an example of using TensorflowInferenceInterface to for object detection with YOLO. It is heavily based on Google's example app, but has been trimmed to only include YOLO. See the full documentation on this project here.
The .pb (protobuf) file in app/src/main/assets is used to store a Tensorflow neural net and currently contains a trained network which detects robots and red and blue wiffle balls.
