Stop robot before hitting a wall using an ultrasonic sensor

This video describes how to program a Lego Mindstorms EV3 robot to stop before it hits a wall. It detects the distance from the wall using an ultrasonic sensor.

The programming is done on a Chromebook using the Lego EV3 Education programming app. Since the Lego EV3 Education programming app on the Chromebook is similar to the same app on the iPad, the example should be usable on the iPad also.
