Sphero is one of our favourite programmable robots, especially at this time of year when you can take it outdoors. It's a tough spherical robot that is even waterproof.
Sphero SPRK+ is an updated version of the Sphero SPRK edition which introduced a transparent body and the Sphero SPRK educational app.

The SPRK+ has added a scratch-resistant coating and Bluetooth Smart touch to tap pairing which is useful in an educational environment where you have multiple robots in use at the same time. (Pairing multiple Bluetooth devices in a classroom can be a painful experience, so this feature will be very welcome to teachers, librarians and club and camp leaders.)
SPRK+ is available to order. It has been released in time for the start of the new academic year. The SPRK app (available for iOS, Android and Kindle Fire) has also received an update.
Last year's Sphero SPRK robot can sometimes be found for a reduced price. Paying the extra for the features of the SPRK+ won't necessarily make sense for families.
Note that while original Sphero apps work with the SPRK, they haven't yet been updated to work with SPRK+ (we'll keep a look out for updates, apps support for BB-8 was added after its release.)
