Autonomous BB-8 Drive System

This is meant to help current BB-8 builders to put their rolling droid’s abilities to the next level. I am currently building a slightly modified model to accommodate for the ultrasonic sensor, but until that is finished, I am posting this because I believe it to be one of the next steps in the BB-8 building community. It uses an ultrasonic sensor to measure distance, this portion is in the dome. It then sends a signal if the BB-8 approaches an obstacle, and the drive-train reacts accordingly. In order to configure the bluetooth modules, I have made a separate instructable linked here, for there are many different versions, and they are hard to configure.”
