Remember the BB-8 App-enabled Droid from Sphero? It is a wonderful robot that recognizes and reacts to your voice. It is already compatible with iOS and Android smartphones, but you can use the Force Band to interact with your robot a whole new way.
You will be able to use the Force to push, pull, and control your BB-8. It has a wireless range of 30 meters. What to practice wielding a lightsaber? No problem. There are also digital Holocrons for you to discover. More info is available here.
