Spheros are robotic balls (spheros.us) that you can control with an iPad. Spheros are cool because you can make them go in any direction with the app called Macro Lab. Our school purchased some Spheros. We are making mazes, and then programming the Spheros to do the maze. The Sphero can change colors and connect to Bluetooth. You can get Spheros anywhere online and anywhere, pretty much. We also made chariots and raced them on a track. We had a fun time working with the Spheros. You can get Spheros covers in different colors.
