Nearly two years ago, Sphero decided to turn its robot ball into more than a toy. The company launched SPRK, an educational program for kids to build up their coding skills, as a complement to its charming connected device. Then, in 2015, it followed that up with the Sphero SPRK Edition, a redesigned version with a clear shell and a companion app that let users set up commands for the robot to follow. Now Sphero is introducing the second generation of its education-focused ball, dubbed SPRK+. It's a minor but still noteworthy upgrade compared to the original version.
