UI Sketches

Main drive screen

1. Web cam feed at the top (if we do a webcam feed)
2. D-Pad controller touch area below. User swipes (or click/touch) to tell robot which direction to drive in
3. Underneath drive controls, set command delay in seconds
4. Under that, buttons to set other options and build your own autonomous rules

Rule builder

Easy rule builder, adapting Tiago Jesus original desktop interface for smaller, mobile devices https://github.com/tiagojesus/LegoRoversUI
