As the GK said, the Sphero robot ball costs a whopping $130, which seems like a great deal of money for a plastic ball, even if it is high-tech a “robot” and can be controlled via your smart device. For that kind of money, you can find a Nintendo 3DS on sale or a refurbished iPod Touch. Both of which are more engaging to both myself and the Gadgeteer Kid. While well made and with a growing set of associated apps, (IMO) Sphero is more like a $50-60 niche device, definitely not worth three figures.

Multiple Sphero balls can be controlled at one time using separate control devices. One Sphero can also be controlled by multiple devices. Those devices include any Android or iOS device. Sphero balls can also be used as a controller for games on your Android or iOS device by holding it to tilt, turn, and aim.
What happens when you put a couple of robotics engineers in a room and tell them to have fun? Sphero. The Orbotix team is comprised of some really bright engineers who have taken their combined knowledge and turned it into the re-invention of the two-wheeled gyroscopic toy. The insides of the Sphero ball contain a pair of batteries, the wheels to drive the ball, an arm to keep the wheels on the ground, and an army of chips, sensors, and wires to help control and drive the ball.
