DrGraeme's video: 16 How to use the ball as a back wheel for our LEGO EV3 Education set Robot LucyBot

This video tutorial is appropriate for users of the EV3 Education Kit only. It shows how to use the ball as a back "wheel" for your converted Robot LucyBot. It is appropriate for users of the Lego EV3 Education Kit only, because it uses some components that are supplied with the Education Kit, but not with the Home Kit. If you are using the Lego EV3 Home Kit, you should ignore this video tutorial, and go on to Video 17 in this YouTube playlist. Our experience is that both versions of this EV3 Robot LucyBot work equally well with the Tutorials and Challenges that follow. This tutorial do not have Closed Captions. I hope to add these when I have time. Playlist Index: Video 1: Ying Chen introduces this fun series of LEGO EV3 tutorial lessons. Videos 2: Yaya demonstrates how to build your first robot.
