Sphero

The world's first robotic ball you control with a tilt, tap, or touch on your smartphone or tablet. Sphero 2.0 rolls at speeds of up to 4.5 mph and pairs to your device via Bluetooth with a range of up to 100 feet. Powered by induction charging, Sphero 2.0 is three times brighter than the original and is pet proof, waterproof, and ready for any adventure. We used both the app-controlled and programmable Spheros. The programmable Sphero uses the SPRK app which lets you give your robot orders with visual blocks representing code - their own C-based language called OVAL. SPRK is simple enough for beginners of all ages, yet sophisticated enough for seasoned programmers.
