Sphero
You'll find the Sphero robots and the iPads under the 3D printers. Use the tutorial on the right to learn how to start using your Sphero for the first time and how to get to the first three programming challenges.
When you're done using Sphero, make sure to connect the iPad to the charging cable and place Sphero back onto his charger for the next class. You'll know that Sphero is charging when he lights up in a rainbow pattern on his charging station. It may take a few seconds or so for the lights to turn on.
